Abstract
Two novel plant growth-promoting, rod-shaped, Gram-positive and non-motile rhizobacteria, W1NT and W2RT, were isolated from wetland plants Festuca elata and Nymphoides peltatum, respectively, in China. The results of the 16S rRNA sequence alignment analysis showed that they were related to Microbacterium, with the highest similarity to Microbacterium ketosireducens (98.7 %) and Microbacterium laevaniformans (98.5 %) for strain W1NT, and to Microbacterium terricola (98.1 %) and Microbacterium marinum (98.0 %) for strain W2RT. Phylogenetic analyses based on 16S rRNA gene sequences and 92 conserved concatenated proteins suggested that the two strains belong to the genus Microbacterium and were placed in two separate novel phylogenetic clades. The genome sizes of the two strains were 3.2 and 3.7 Mb, and the G+C contents were 71.7 and 68.5 mol%, respectively. The comparative genome results showed that the average nucleotide identity values between W1NT and W2RT and other species ranged from 73.5 to 83.6 %, and the digital DNA-DNA hybridization values ranged from 19.7 to 26.8 %. These two strains show physiological and biochemical features that differ from those of closely related species. Rhamnose, galactose and glucose were present in the characteristic sugar fractions of strains W1NT and W2RT. The peptidoglycan of strains W1NT and W2RT contained the amino acids ornithine, alanine and aspartic acid. C15 : 0 anteiso, C17 : 0 anteiso and C16 : 0 iso were the predominant cellular fatty acids in W1NT and W2RT. Phosphatidylglycerol and diphosphatidylglycerol are major polar lipid components. Strain W1NT not only formed bacterial biofilms but also had the ability to solubilize phosphorus and produce indole-3-acetic acid. Strain W2RT had siderophore-producing and lignin-degrading properties. Based on their genetic and phenotypic characteristics, strains W1NT and W2RT were classified as novel bacteria in the genus Microbacterium and designated as Microbacterium festucae sp. nov. (type strain W1NT=ACCC 61807T=GDMCC 1.2966T=JCM 35339T) and Microbacterium nymphoidis sp. nov. (type strain W2RT=ACCC 61808T=GDMCC 1.2967T=JCM 35340T).

Abstract
An isolate of Gram-stain-negative and strictly aerobic bacterium, designated KC 17139T, was isolated from Jiaozi Mountain sample in Yunnan, China. Cells were non-motile cocci to oval, catalase-positive and oxidase-positive. Growth occurred at 0-7% NaCl (w/v; optimum, 0%), pH 6.0-8.0 (optimum, pH 7.0) and 15-45 °C (optimum, 28-37 °C). The polar lipids were diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylcholine (PC) and four unidentified aminolipids (UALs). Strain KC 17139T contained summed feature 8 (comprising C18:1 ω7c and/or C18:1 ω6c), C18:1 2OH and C16:0 as major cellular fatty acids (> 5%) and ubiquinone-10 as the sole isoprenoid quinone. The 16S rRNA gene sequence analysis indicated that strain KC 17139T shared highest similarities with Siccirubricoccus phaeus 1-3T (96.7%) and Siccirubricoccus deserti SYSU D8009T (95.0%). Strain KC 17139T clustered with the two Siccirubricoccus type strains, but formed a separate branch in both 16S rRNA gene and genome-scale phylogenetic dendrograms. The genomic DNA G + C content of strain KC 17139T was 71.2%. Genomic comparisons between strain KC 17139T and its close relatives showed the highest digital DNA-DNA hybridisation to S. phaeus (35.5%), highest average nucleotide identity to S. phaeus (88.2%), indicating that strain KC 17139T represents a novel species. On the basis of results of phenotypic, chemotaxonomic and molecular analysis, we report a new bacterium strain KC 17139T belonged to genus Siccirubricoccus, for which the name Siccirubricoccus soli sp. nov. is proposed. The type strain is KC 17139T (= CGMCC 1.18756T = JCM 35132T).

Abstract
A novel actinobacterial strain, designated SYSU K20354T, was isolated from a soil sample collected from a karst cave in Shaoguan city, Guangdong province, southern China. The taxonomic position of the strain was investigated using a polyphasic approach. Cells of the strain were aerobic, Gram-stain-positive and non-motile. On the basis of 16S rRNA gene sequence similarities and phylogenetic analysis, strain SYSU K20354T was most closely related to Agromyces humatus JCM 14319T, and shared the highest sequence identity of 98.3 % based on NCBI database. In addition, 2,4-diaminobutyric acid was the diagnostic diamino acid in cell-wall peptidoglycan. The whole-cell sugars were galactose, glucose, mannose and ribose. The major isoprenoid quinone was MK-12, while the major fatty acids (>10 %) were iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, three unknown glycolipids, three unknown phospholipids and two unknown lipids. The draft genome size of strain SYSU K20354T was 3.96 Mbp with G+C content of 69.7 mol%. Furthermore, the average nucleotide identity and digital DNA-DNA hybridization values between strain SYSU K20354T and A. humatus JCM 14319T were 90.3 and 55.6 %, respectively. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU K20354T represents a novel species of the genus Agromyces, for which the name Agromyces cavernae sp. nov. is proposed. The type strain is SYSU K20354T (=KCTC 49499T= CGMCC 4.7691T).

Abstract
Two novel species of the genus Deinococcus, designated SYSU M49105T and SYSU M42101T, were isolated from freshwater samples of the Pearl River estuary in Guangdong, China. Phylogenetic analysis using 16S rRNA gene sequence indicated that strains SYSU M49105T and SYSU M42101T showed the highest sequence similarities to Deinococcus aetherius JCM 11751 T (93.6%) and Deinococcus multiflagellatus NBRC 112888 T (97.3%), respectively. Cells of both strains were Gram-staining positive, aerobic, coccus-shaped, oxidase-negative and non-motile. The cell wall contained meso-diaminopimelic acid as their diagnostic diamino acid. MK-8 was the predominant respiratory quinone for both strains. The polar lipid profile of SYSU M49105T contained two unidentified phosphoglycolipids, nine unidentified glycolipids, and five unidentified polar lipids. SYSU M42101T had one unidentified phosphoglycolipid, nine unidentified glycolipids, one unidentified aminophospholipid and four unidentified polar lipids. The major fatty acids of strains SYSU M49105T and SYSU M42101T were summed feature 3 (C16:1 ω7c and/ or C16:1 ω6c) and C16:0. The G + C contents of the novel isolates based on genomic DNAs were 69.6% and 67.4%, respectively. On the basis of phenotypic, genotypic and phylogenetic data, strains SYSU M49105T and SYSU M42101T should be considered to represent two novel species in the genus Deinococcus, for which the names Deinococcus aestuarii sp. nov. and Deinococcus aquaedulcis sp. nov. were proposed with the type strains SYSU M49105T (= KCTC 43258 T = CGMCC 1.18609 T) and SYSU M42101T (= KCTC 43257 T = CGMCC 1.18614 T), respectively.

Abstract
A novel species of the genus Roseomonas, designated SYSU M41301T, was isolated from water sample of the Pearl River estuary in Guangdong, China. Polyphasic, taxonomic and phylogenomic analyses were used to determine the taxonomy position of the strain. Phylogenetic analysis using 16S rRNA gene sequence indicated that strain SYSU M41301T showed the highest sequence similarity to Roseomonas stagni KCTC 22213T (97.9 %) and Roseomonas riguiloci KCTC 23339T (96.4 %). The novel species could be differentiated from other species of the genus Roseomonas by its distinct phenotypic and genotypic characteristics. The isolate was Gram-staining-negative, aerobic, short rod-shape, oxidase-positive and non-motile. The predominant respiratory quinone was ubiquinone 8 (Q-8). The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, and one unidentified polar lipid. The major fatty acids (>10 % of total) were 11-methyl C18 : 1 ω7c, summed feature 3 (C16 : 1 ω7c and/ or C16 : 1 ω6c) and summed feature 8 (C18: :1 ω7c and/or C18 : 1 ω6c). The G+C content of the novel isolate based on genomic DNA was 72.0 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU M41301T should be considered to represent a novel species in the genus Roseomonas, for which the name Roseomonas ponticola sp. nov. is proposed with the type strain SYSU M41301T (=KCTC 72726T=CGMCC 1.18613T).

Abstract
During the investigation of exploring potential sources of novel species and natural bioactives, a novel actinomycete, designated strain HIT-DPA4T, was isolated from a soil sample, which was collected from Nanjing, Jiangsu Province, PR China and characterized using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities and the result of phylogenetic analysis, strain HIT-DPA4T was most closely related to Streptomyces cyaneus CGMCC 4.1671 T, and shared the highest sequence similarity of 98.76%. In addition, the cell walls of the species HIT-DPA4T contained LL-diaminopimelic acid as the diagnostic diamino acid and the whole-cell hydrolysates were identified as glucose and ribose, and the principal phospholipids were found to be diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol mannoside and phosphatidylmonomethylethanolamine. MK-9(H6) and MK-9(H4) were predominant menaquinones; and C16:0, anteiso-C15:0 and C15:0 as major cellular fatty acids of the organism HIT-DPA4T. Gene Ontology database analysis and antiSMASH server predicted results displayed that strain HIT-DPA4T was a promising classification units, which has various types of functions and contains multiple biosynthetic gene clusters with the similarity more than 80%. Multilocus sequence analysis (MLSA) of five housekeeping genes (atpD, gyrB, recA, rpoB and trpB) illustrated that Streptomyces luteolifulvus formed a separate branch in the genus Streptomyces. However, a combination of low level of DNA-DNA relatedness and physiological properties indicated that strain HIT-DPA4T can be distinguished from its phylogenetically related species Streptomyces cyaneus CGMCC 4.1671 T. Moreover, gene synteny research could be further differed organism HIT-DPA4T from similarity species. Therefore, the strain is concluded to represent a novel species of the genus Streptomyces, for which the name Streptomyces luteolifulvus sp. nov. is proposed. The type strain is HIT-DPA4T (= CGMCC 4.7558 T = TISTR 2751 T).

Abstract
A novel filamentous Actinobacterium, designated strain FXJ1.1311T, was isolated from soil collected in Ngari (Ali) Prefecture, Qinghai-Tibet Plateau, western PR China. The strain showed antimicrobial activity against Gram-positive bacteria and Fusarium oxysporum. Results of phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FXJ1.1311T belonged to the genus Lentzea and showed the highest sequence similarity to Lentzea guizhouensis DHS C013T (98.04%). Morphological and chemotaxonomic characteristics supported its assignment to the genus Lentzea. The genome-wide average nucleotide identity between strain FXJ1.1311T and L. guizhouensis DHS C013T as well as other Lentzea type strains was <82.2 %. Strain FXJ1.1311T also formed a monophyletic line distinct from the known Lentzea species in the phylogenomic tree. In addition, physiological and chemotaxonomic characteristics allowed phenotypic differentiation of the novel strain from L. guizhouensis. Based on the evidence presented here, strain FXJ1.1311T represents a novel species of the genus Lentzea, for which the name Lentzea tibetensis sp. nov. is proposed. The type strain is FXJ1.1311T (=CGMCC 4.7383T=DSM 104975T).

Abstract
A novel actinomycete, designated as strain WCH-YHL-001T, was isolated from skin biopsy specimens of a patient at West China Hospital, Chengdu, Sichuan Province, PR China. The cells were Gram-positive, aerobic, heterotrophic and non-motile. They formed an extensive substrate with short aerial mycelia, whose branches fragmented into rod-shaped elements. Growth occurred at 10-40 °C, pH 5.0-12.0 and with NaCl concentrations of 0-4.0 % (w/v). The major cellular fatty acids of strain WCH-YHL-001T were C16 : 0, C18 : 1 ω9c, C18 : 0 10-methyl and summed feature 3. The predominant respiratory quinone was MK-8 (H4ω-cycl). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside, unknown phospholipids and unidentified glycolipids. The diagnostic diamino acid of peptidoglycan was meso-diaminopimelic acid. The whole-cell sugar pattern consisted of arabinose and glucose. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain WCH-YHL-001T belonged to the genus Nocardia. The average nucleotide identity (ANI) and in silico DNA-DNA hybridization (isDDH) values between strain WCH-YHL-001T and type strains of Nocardia species were lower than the cut-offs (≥95-96 % for ANI and ≥70 % for isDDH) required to define a bacterial species. The genomic DNA G+C content was 67.8 mol%. Phylogenetic, physiological and chemotaxonomic data suggested that strain WCH-YHL-001T represented a novel species of the genus Nocardia, for which the name Nocardia huaxiensis sp. nov. is proposed, with the type strain WCH-YHL-001T (=GDMCC 4.181T=JCM 34475 T=NBRC 114973T).

Abstract
A Gram-negative, yellow-pigmented, rod-shaped bacterial strain YIM B02567T was isolated from the root of Paris polyphylla Smith var. yunnanensis in China. Strain YIM B02567T grew optimally at 25-30 °C and at pH 7.0 in the absence of NaCl on nutrient agar. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain YIM B02567T belong to the genus Chryseobacterium, and was closely related to Chryseobacterium piperi CTMT and Chryseobacterium soli DSM 19298T. Whole genome sequencing indicated that the genome size was 4,774,612 bp and with a G + C content of 34.5 mol%. Values of the ANI and the dDDH between strain YIM B02567T and its closely related Chryseobacterium species were below 81.72% and 24.7%. Strain YIM B02567T contained menaquinone-6 as the sole isoprenoid quinone, anteiso-C15:0, iso-C17:1 ω9c and iso-C17:0 3-OH as major fatty acids and phosphatidylethanolamine as major polar lipid. Based on the polyphasic analyses, strain YIM B02567T could be differentiated genotypically and phenotypically from recognized species of the genus Chryseobacterium. The isolate, therefore, represents a novel species, for which the name Chryseobacterium paridis sp. nov. is proposed. The type strain is YIM B02567T (= CGMCC 1.18657T).

Abstract
A novel actinobacterium, designated CFH 10395T, was isolated from the foregut of grass carp (Ctenopharyngodon idella), which had been fed with ginseng extract supplement. The taxonomic position was investigated by a polyphasic approach. Cells of CFH 10395T were Gram-staining-positive, aerobic, ovoid-shaped, non-spore-forming and non-motile. On the basis of the results of 16S rRNA gene sequence analysis, CFH 10395T was most closely related to Brachybacterium endophyticum KCTC 49087T, Brachybacterium squillarum JCM 16464T and Brachybacterium paraconglomeratum JCM 17781T (97.85%, 97.51 and 97.29% similarity, respectively). CFH 10395T grew at 4-37 °C, pH 5.0-9.0 and in the presence of up to 10.0 % NaCl (w/v). The dominant menaquinone was MK-7. The whole-cell sugars were rhamnose, glucose, mannose and galactose. meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The major fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The genome size was 3.99 Mbp with a DNA G+C content of 71.9 mol%. On the basis of the results of phylogenetic analysis, physiological properties, chemotaxonomic characteristics, low average nucleotide identity (ANI) and digital DDH (dDDH) results [ANI calculated using MUMmer (ANIm) <87 %, ANI calculated using blast (ANIb) <83 % and dDDH <23 %], it is concluded that CFH 10395T represents a novel species of the genus Brachybacterium, for which the name Brachybacterium subflavum sp. nov., is proposed. The type strain is CFH 10395T (=CGMCC 1.13804T=KCTC 49235T).

Abstract
A novel Gram-staining negative, crescent-like or rod-shaped, non-motile bacterium, designated strain CUG 91378 T, was isolated from a sediment sample of Qinghai Lake, Qinghai Province, China. The strain was red-colored, and catalase- and oxidase-positive. Strain CUG 91378 T was able to grow at 15-37 °C (optimum, 28 °C), pH 7-9 (pH 7.0) and in the presence of up to 3.0% (w/v) NaCl (0-2%). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CUG 91378 T formed a well-supported monophyletic clade with Aquiflexum balticum DSM 16537 T (95.4%) and Aquiflexum aquatile Z0201T (93.2%). The DNA G + C content of CUG 91378 T was 39.0%. Low (< 87%) average nucleotide identity (ANI) and (< 26%) digital DNA-DNA hybridization (dDDH) values were observed between strain CUG 91378 T and its closest species on the phylogenetic trees. The sole respiratory quinone of strain CUG 91378 T was MK-7. The predominant fatty acids (> 5.0%) were iso-C15:0 (19.1%), iso-C16:0 (12.0%), iso-C16:1 H (10.9%), iso-C16:0 3OH (9.2%), iso-C17:0 3OH (7.7%), C17:1ω6c (6.1%) and anteiso-C15:0 (5.8%). Strain CUG 91378 T contained as phosphatidylethanolamine (PE), phosphatidylglycerol (PG) and four unidentified lipids (L1, L2, L3 and L4). Based on the data from the current polyphasic study, the isolate represents a novel species of the genus Aquiflexum for which the name Aquiflexum lacus is proposed. The type strain of the proposed new taxon is CUG 91378 T (= KCTC 62637 T = CGMCC 1.13988 T).

Abstract
Strain CFH S0501T, a novel Gram-stain-positive, aerobic, rod-shaped, endospore-forming and motile micro-organism with peritrichous flagella, was isolated from a sediment sample collected from the Yellow River in Henan Province, PR China. Optimum growth was observed at 28 °C, pH 7.0 and without NaCl. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the strain belonged to the genus Brevibacillus and was closely related to Brevibacillus centrosporus DSM 8445T and Brevibacillus ginsengisoli Gsoil 3088T (with 96.8 and 96.7 % sequence similarity, respectively). The predominant menaquinone was MK-7. Major cellular fatty acids were anteiso-C15 : 0 and iso-C15 : 0. Polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, two unidentified phospholipids and an unidentified polar lipid. The cell-wall peptidoglycan was found to contain meso-diaminopimelic acid. The genome size was 5.26 Mbp with a G+C content of 49.7 mol%. The average nucleotide identity (ANI) and in silico DNA-DNAhybridization (DDH) values between CFH S0501T and the other species of the genus Brevibacillus were found to be low (ANIm <86.11 %, ANIb <70.30 % and DDH <25.00 %). Based on physiological properties, chemotaxonomic characteristics and low ANI and DDH results, strain CFH S0501T is considered to represent a novel species, for which the name Brevibacillus migulae sp. nov. is proposed. The type strain is CFH S0501T (=DSM 29940T=BCRC 80809T).

The strain grew at 4-45 °C, pH 5.0-9.0 and with 0-14.0 % (w/v) NaCl. Cells were positive for catalase, nitrate was not used and H2S was not produced. Major cellular fatty acids were anteiso-C15 : 0 (62.76 %), anteiso-C17 : 0 (12.09 %) and iso-C15 : 0 (9.46 %). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two unidentified phospholipids and three unidentified glycolipids. The menaquinone was MK-9 (H4). The genome size was 4.10 Mbp with a G+C content of 72.4 mol%. The average amino acid identity (ANI) and in silico DNA-DNA hybridization (DDH) values between CFH 91151T and the other species of the genus Isoptericola were found to be low (ANIm <87.19 %, ANIb <84.38 % and DDH <29.30 %). Based on physiological properties, chemotaxonomic characteristics and low ANI and DDH results, strain CFH 91151T is considered to represent a novel species, for which the name Isoptericola halalbus sp. nov. is proposed. The type strain is CFH 91151T (=DSM 105976T=KCTC 49061T).

Abstract
A novel nocardioform strain, CICC 11023T, was isolated from a tissue biopsy of neck lesions of a patient with primary cutaneous nocardiosis and characterized to establish its taxonomic position. The morphological, biochemical, physiological and chemotaxonomic properties of strain CICC 11023T were consistent with classification in the genus Nocardia. Whole-cell hydrolysates were rich in meso-diaminopimelic acid, galactose, arabinose and fructose. Mycolic acids were present. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, one unidentified phospholipid and two unidentified lipids, and the predominant menaquinone was cyclo MK-8 (H4, ω-cyclo). The main fatty acids (>5 %) were C18 : 0 10-methyl (TBSA), C16 : 0, summed feature 4 (C16 : 1 trans 9/C15 : 0 iso 2OH), C15 : 0 and C17 : 0 10-methyl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the isolate is most closely related (>98 % similarity) to the type strains Nocardia ninae OFN 02.72T, Nocardia iowensis UI 122540T and Nocardia alba YIM 30243T, and phylogenetic analysis of gyrB gene sequences showed similarity (89.1–92.2 %) to Nocardia vulneris NBRC 108936T, Nocardia brasiliensis IFM 0236T and Nocardia exalbida IFM 0803T. DNA–DNA hybridization results for strain CICC 11023T compared to Nocardia type strains ranged from 20.4 to 35.4 %. The genome of strain CICC 11023T was 8.78 Mbp with a G+C content of 67.4 mol% overall. The average nucleotide identity (ANI) values between strain CICC 11023T and N. alba YIM 30243T were low (OrthoANIu=77.47 %), and the ANI values between strain CICC 11023T and N. vulneris NBRC 108936 T were low (OrthoANIu=83.75 %). Consequently, strain CICC 11023T represents a novel Nocardia species on the basis of this polyphasic study, for which the name Nocardia colli sp. nov. is proposed. The type strain is CICC 11023T (=KCTC 39837T).

Abstract
A bacteria strain, designated CFH 90008T, was isolated from a salt lake sediment sample collected from Yuncheng city, Shanxi Province, PR China. Strain CFH 90008T was Gram-stain-negative, strictly aerobic, motile with lateral flagella and rod-shaped. Colonies were yellow, circular and smooth. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain CFH 90008T belonged to the genus
Halomonas
, showing highest sequence similarity to
Halomonas daqingensis
DQD2-30T (98.6 %),
Halomonas saliphila
LCB169T (98.5 %),
Halomonas desiderata
FB2T (98.1 %) and
Halomonas kenyensis
AIR-2T (98.0 %). Good growth was observed at 10–50 °C, pH 6.0–9.0 and with NaCl concentration from 1.0 to 12.0 % (w/v). The predominant quinone was Q9. The major fatty acid (>10 %) was C18 : 1 ω7c, C16 : 0 and C16 : 1 ω7c. The genome of strain CFH 90008T was 4.36 Mbp with a genomic DNA G+C content of 66.7 mol%. Based on low average nucleotide identity and DNA–DNAhybridization results, chemotaxonomic characteristics, and differential physiological properties, strain CFH 90008T could not be classified into any recognized species of the genus
Halomonas
. Therefore, a new species, for which the name Halomonas lactosivorans sp. nov. is proposed. The type strain is CFH 90008T (=DSM 103220T=KCTC 52281T).

Abstract
A novel actinobacterium, designated strain CFH S0261T, was isolated from a sediment sample of the Yellow River. The taxonomic position of the strain was investigated by using a polyphasic approach. Cells of strain CFH S0261T were Gram-reaction-positive, aerobic, non-motile. Growth occurs at 15-37 °C, pH 6.0-8.0 and with 0-9.0 % (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain CFH S0261T was a member of the genus Amycolatopsis. The 16S rRNA gene sequence similarity indicated that strain CFH S0261T is most closely related to the type strains of Amycolatopsis niigatensis LC11T (98.95 %), Amycolatopsis echigonensis LC2T (98.81 %) and Amycolatopsis albidoflavus IMSNU 22139T (98.73 %). The whole-genome of CFH S0261T showed a G+C content of 69.5 mol%. The ANI values and in silico DDH values between CFH S0261T and the other species of the genus Amycolatopsis were found to be low (ANIb <90.61 % and DDH <53.40 %). The cell wall diamino acid in the peptidoglycan of strain CFH S0261T was meso-diaminopimelic acid and the whole-cell hydrolysate comprised arabinose, galactose, glucose, rhamnose and ribose. The predominant menaquinone was MK-9(H4). The major cellular fatty acids were C16 : 0, iso-C15 : 0 and iso-C16 : 0. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and four unidentified glycolipids. On the basis of phenotypic, genotypic and phylogenetic data, strain CFH S0261T represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis nivea sp. nov. is proposed. The type strain is CFH S0261T (=KCTC 39515T =CCTCC AA 2014028T).

Abstract
A novel thermophilic bacterium, designated CFH 72773T was isolated from the enrichment of a Jinze hot spring sample which was collected from Dientan town, Tengchong county, Yunnan province, south-western PR China. Cells were Gram-stain-negative, aerobic, non-motile, rod-shaped and non-sporulating. The taxonomic position of the strain was investigated by using a polyphasic approach. Growth occurred at 37-75 °C, pH 6.0-8.0 and with 0-2.0 % (w/v) NaCl. Comparison of the 16S rRNA gene sequences indicated the strain represented a member of the genus Thermus and showed close relationships to the type strains Thermus caliditerrae YIM 77925T (96.3 % similarity) and Thermus igniterrae RF-4T (96.2 % similarity). The whole genome of CFH 72773T consisted of 2.25 Mbp and the DNA G+C content was 69.5 mol%. A total of 2262 genes, including a variety of enzymes for chemolithotrophy and anerobic respiration, were predicted. The strain had a unique negative oxidase activity and could hydrolyze starch at high temperature. Furthermore, various genes related to methane, sulfur, fumarate and nitrate metabolism were found, all these indicated that it is worth studying the novel strain. The predominant menaquinone is MK-8. The predominant cellular fatty acids included iso-C15 : 0, iso-C16 : 0 and iso-C17 : 0. The major polar lipids were comprised of aminophospholipid, glycolipid and two phospholipids. On the basis of low ANI values, different phenotypic and chemotaxonomic characters and phylogenetic analysis, we made a proposal that strain CFH 72773T represents a novel member of the genus Thermus, for which the name Thermus thermamylovorans sp. nov. is proposed. The type strain is CFH 72773T (=CCTCC AB2018244T=KCTC 43129T).

Abstract
A novel actinobacterial strain, designated SYSU K12189T, was isolated from a soil sample collected from a Karst cave in Xingyi county, Guizhou province, south-western China. The taxonomic position of the strain was investigated using a polyphasic approach. Cells of the strain were observed to be aerobic and Gram-stain positive. On the basis of 16S rRNA gene sequence similarities and phylogenetic analysis, strain SYSU K12189T is closely related to the type strains of the genus Microlunatus, Microlunatus parietis 12-Be-011T (98.5% sequence similarity), Microlunatus nigridraconis CPCC 203993T (98.4%) and Microlunatus cavernae YIM C01117T (96.6%), and is therefore considered to represent a member of the genus Microlunatus. DNA-DNA hybridization values between strain SYSU K12189T and related type strains of the genus Microlunatus were < 70%. In addition, LL-diaminopimelic acid was found to be the diagnostic diamino acid in the cell wall peptidoglycan. The major isoprenoid quinone was identified as MK-9(H4), while the major fatty acids (> 10%) were found to be anteiso-C15:0, iso-C15:0, iso-C16:0 and iso-C14:0. The polar lipids were found to contain diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, three glycolipids and two unidentified lipids. The genomic DNA G+C content of strain SYSU K12189T was determined to be 69.4 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU K12189T is concluded to represent a novel species of the genus Microlunatus, for which the name Microlunatus speluncae sp. nov. is proposed. The type strain is SYSU K12189T (= KCTC 39847T = DSM 103947T).

Abstract
A Gram-staining positive and nonmotile strain designated SYSUP0005T was isolated from tubers of Gastrodia elata Blume. The 16S rRNA gene sequence result showed that strain SYSUP0005T shared highest sequence similarity with the type strain of Amycolatopsis cappadoca (95.7%), Amycolatopsis taiwanensis (95.4%), Amycolatopsis pigmentata (95.4%), Amycolatopsis ruanii (95.1%), and Amycolatopsis helveola (94.8%). Growth occurs at 14-37 °C (optimum temperature, 28 °C), at pH 6-9 (optimum, pH 8) and in the presence of up to 6% (w/v) NaCl. Strain SYSUP0005T had meso-diaminopimelic acid in its peptidoglycan. The whole cell sugars were galactose, ribose, and xylose. The predominant menaquinone was MK-9(H4) and minor menaquinones were MK-9(H2) and MK-9(H8). The polar lipids were diphosphatidylglycerol (DPG); phosphatidylmonomethylethanolamine (PME), phosphatidylethanolamine (PE), phosphatidylinositol (PI), unidentified glycolipid (GL), and unidentified phospholipid (PL). The genomic DNA G + C content was 69.6 mol%. The major fatty acids were iso-C16:0, anteiso-C17:0, C16:0, iso-C14:0, C17:1 ω6c, C17:0, and Summed Feature 3 (C16:1 ω7c/C16:1 ω6c). On the basis of the phenotypic, phylogenetic, chemotaxonomic characters, and genomic comparison, SYSUP0005T represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis alkalitolerans sp. nov. is proposed. The type strain is SYSUP0005T (=KCTC 49024T = CGMCC4.7463T).

Abstract
Moutai-flavour Daqu is an important starter to support growth of microorganisms in the fermented process of Moutai-flavour liquor. A novel thermophilic microorganism, designated strain FBKL4.011T, was isolated from Moutai-flavour Daqu samples collected from Guotai distillery in Renhuai, Guizhou province, south-west China. The strain could grow at 45-65 °C (optimum 45 °C). Based on polyphasic analysis, strain FBKL4.011T was affiliated to the genus Thermoflavimicrobium. It formed abundant pale-yellow aerial and substrate mycelium, bearing single endospores (7.0-10.0 µm diameter) on branched long sporophores (5.0 µm diameter). The cell-wall peptidoglycan contained meso-diaminopimelic acid; ribose, glucose and mannose were the primary whole-cell sugars. The major fatty acids were iso-C14 : 0, iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0. The predominant menaquinone were MK-8 and MK-9. The polar phospholipids contained diphosphatidyl glycerol, phosphatidyl ethanolamine, one unidentified phospholipid and one unidentified lipid. The G+C content of the genome was 43.1 mol%. According to the 16S rRNA gene sequence analysis, strain FBKL4.011T was closely related to Thermoflavimicrobium dichotomicum JCM 9688T (95.3 % sequence similarity), and other members within the family Thermoactinomycetaceae (less than 93.0 % sequence similarity). The DNA-DNA hybridisation data showed low relatedness between strain FBKL4.011T and T. dichotomicum JCM 9688T, Laceyella sacchari KCTC 9790T, Laceyella tengchongensis YIM 10002T, Laceyella sediminis RHA1T(36.7±1.1 %, 30.0±1.2 %, 21.3±2.1 % % and 37.6±0.9 %, respectively). Based on data from the polyphasic analysis, strain FBKL4.011T is considered to represent a novel species of the genus Thermoflavimicrobium, for which the name Thermoflavimicrobium daqui sp. nov. is proposed. The type strain is FBKL4.011T(=KCTC 43036T=CICC 24504T).

Abstract
Strain SYSU D60016T, a rod-shaped bacterium that tends to form clusters, was isolated from a soil sample collected from the Gurbantunggut desert, China. Cells were Gram-stain-negative, catalase-negative and oxidase-positive. The 16S rRNA gene sequence of strain SYSU D60016T shared less than 94 % sequence identity with members of the family Hymenobacteraceae. The strain exhibited growth at 15-50 °C, pH 6-8 and in the presence of up to 3 % (w/v) NaCl. Its chemotaxonomic features included MK-7 as the respiratory menaquinone, iso-C15 : 0 and summed feature 4 (iso-C17 : 1 I and/or anteiso-C17 : 1 B) as major cellular fatty acids and phosphatidylethanolamine as the main polar lipid. The DNA G+C content was determined to be 50.1 % (genome). Analyses of the phylogenetic data and differences in the chemotaxonomic and biochemical features from related genera in the family Hymenobacteraceae indicated that strain SYSU D60016T merits representation of a novel species of a novel genus in the family Hymenobacteraceae. The name Botryobacter ruber gen. nov., sp. nov. is, therefore, proposed to represent the phylogenetic position of strain SYSU D60016T in the family Hymenobacteraceae. The type strain of the proposed new taxon is SYSU D60016T (=KCTC 52794T=NBRC 112957T).

Abstract
A motile, rod-shaped and yellow coloured proteobacterium, designated strain SYSU D60017T, was isolated from a desert soil sample. The bacterium was found to be an obligately aerobic, mesophilic and neutrophilic chemo-heterotroph. Cells were observed to be Gram-stain negative, catalase positive and oxidase positive. The major cellular fatty acids were identified as C19:0ω8c cyclo and Summed Feature 8 (C18:1ω7c and/or C18:1ω6c). The main respiratory quinone identified was ubiquinone-10. The DNA G + C content was determined to be 63.8% based on draft genome sequence data. The polar lipids detected were identified as diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and five unidentified polar lipids. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SYSU D60017T is a member of the order Rhizobiales, but forms a distinct phylogenetic lineage. The differences in the phenotypic characteristics from members of related genera and its distinct phylogenetic position suggested that the isolate SYSU D60017T represents a novel species of a novel genus within the order Rhizobiales, for which the name Flaviflagellibacter deserti gen. nov., sp. nov. is proposed. The type strain of the new taxon is SYSU D60017T (= CGMCC 1.16444T = NBRC 112958T).

Abstract
A Gram-stain-negative, non-motile, short rod and aerobic bacterium, designated strain SYSU M10001T, was isolated from a water sample collected from the coastal region of Pearl River Estuary, Guangdong Province, PR China. Strain SYSU M10001T showed optimal growth at 28 °C, pH 7.0 and in the absence of NaCl. Phylogenetic analyses based on 16S rRNA gene sequences and concatenation of 20 protein markers revealed a distinct lineage for strain SYSU M10001T in the order Rhizobiales. Strain SYSU M10001T showed highest 16S rRNA gene sequence similarities to Hyphomicrobium nitrativorans NL23T (91.1 %) and Hyphomicrobium hollandicum IFAM KB-677T (91.1 %). The respiratory ubiquinone was Q-8. The polar lipids of the strain comprised diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminophospholipid, two unidentified phospholipids and three unidentified lipids. The predominant cellular fatty acids identified were C19 : 0cyclo ω8c, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The G+C content was determined to be 65.5 % (genome). On the basis of differences in the phenotypic, physiological and biochemical characteristics, and results of the phylogenetic analyses, strain SYSU M10001T is proposed to represent a novel species in a novel genus for which the name Aestuariivirga litoralis gen. nov., sp. nov. The type strain of the type species Aestuariivirga litoralis is SYSU M10001T (=NBRC 112960T=KCTC 52945T). Besides, the distinct phylogenetic lineage and the distinct chemotaxonomic profile among the families in the order Rhizobiales indicated that strain SYSU M10001T should represent a new family for which the name Aestuariivirgaceae fam. nov. is proposed.

Abstract
A Gram-stain positive, aerobic, non-motile and short-rod-shaped strain, CFH S00084T, was isolated from a sediment sample of the Yellow River in Henan Province, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CFH S00084T clustered within members of Microbacterium and was most closely related to the type strains Microbacterium yannicii JCM 18959T and Microbacterium arthrosphaerae DSM 22421T (98.97 % and 98.36 % similarity, respectively). The strain grew optimally at 25-37 °C, at pH 7.0 and in 0-3 % (w/v) NaCl. The major whole-cell sugars were rhamnose and glucose. The cell-wall peptidoglycan mainly contained glycine, alanine and ornithine. The menaquinones of strain CFH S00084T were MK-13, MK-12 and MK-11. The major fatty acids detected were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The genome of strain CFH S00084T was 4.03 Mbp with a G+C content of 70.5 mol%. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between CFH S00084T and the other species of the genus Microbacterium were found to be low (ANIm <85 %, ANIb <75 % and dDDH <24 %). The phylogenomic analysis provided evidence for clear phylogenetic divergence between strain CFH S00084T and its closely related type strains. On the basis of the differential physiological properties, chemotaxonomic characteristics and low ANI and dDDH results, strain CFH S00084T is considered to represent a novel species for which the name Microbacteriumureisolvens sp. nov. is proposed. The type strain is CFH S00084T (=KCTC 39802T=DSM 103157T).

Abstract
A Gram-positive and aerobic actinobacterium, strain SYSU D8006T, was isolated from a desert sand sample collected from Gurbantunggut desert, China. Phenotypically, the strain was found to grow at 14-50 °C, pH 6.0-9.0 and in the presence of up to 4% (w/v) NaCl. The chemotaxonomic features of strain SYSU D8006T included menaquinone MK-9(H4) as the respiratory quinone, diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside as known polar lipids, iso-C15:0, iso-C16:0, C17:1ω8c and C18:1ω9c as the predominant fatty acids, and arabinose, galactose and glucose as the whole cell sugars. Strain SYSU D8006T shared the highest 16S rRNA gene sequence identity with Blastococcus jejuensis DSM 19597T (98.2%). Based on the analyses of the phenotypic, genotypic and phylogenetic characteristics, strain SYSU D8006T is characterized to represent a novel species of the genus Blastococcus, for which the name Blastococcus deserti sp. nov. is proposed. The type strain is SYSU D8006T (= CGMCC 1.15935T = KCTC 49026T = CPCC 204618T).

Abstract
A novel actinobacterium, designated strain SYSU K10002T, was isolated from a soil sample collected from a karst cave in Xingyi county, Guizhou province, south-western China. The taxonomic position of the strain was investigated using a polyphasic approach. Cells of the strain were aerobic and Gram-stain-positive. On the basis of 16S rRNA gene sequence similarities and phylogenetic analysis, strain SYSU K10002T was most closely related to the type strains of Nocardiaaltamirensis NBRC 108246T (99.0 % sequence similarity) and Nocardiatenerifensis NBRC 101015T (98.8 %) and is therefore considered to represent a member of the genus Nocardia. DNA-DNA hybridization values between strain SYSU K10002T and the closely related type strains of the genus Nocardia were less than 70 %. In addition, meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The whole-cell sugars were arabinose, ribose and galactose. The major isoprenoid quinone was MK-8(H4,ω-cycl), while the major fatty acids (>10 %) were C16 : 0, C18 : 1ω9c and C18 : 0 10-methyl. The polar lipids contained diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and an unidentified glycolipid. Mycolic acids were present. The genomic DNA G+C content of strain SYSU K10002T was 67.4 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU K10002T represents a novel species of the genus Nocardia, for which the name Nocardiaaurea sp. nov. is proposed. The type strain is SYSU K10002T (=KCTC 39849T=DSM 103986T).

Abstract
A novel actinomycete, designated strain NX62T, was isolated from desert soil obtained from Isolaginsha, Ningxia Hui Autonomous Region, China. Its taxonomic position was determined using a polyphasic approach. The strain shows the typical morphological and chemotaxonomic features of members of the genus Lentzea: slight to dark yellow substrate mycelia and white to greyish white aerial hyphae fragmenting into rod-shaped elements; meso-diaminopimelic acid in the cell wall peptidoglycan; MK-9(H4) and MK-9(H2) as menaquinones; diphosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine and phosphatidylinositol as main polar lipids; iso-C16:0 and iso-C17:0 as major cellular fatty acids; and DNA G+C content of 70.1 mol%. 16S rRNA gene sequence analysis indicated that strain NX62T shows high similarity to Lentzea cavernae SYSU K10001T (99.3%) and Lentzea albida IFO 16102T (98.9%), and formed a monophyletic clade with L. cavernae SYSU K10001T in the phylogenetic tree. Based on a comparison of the phenotypic properties and the low level of DNA-DNA relatedness, strain NX62T can be distinguished from phylogenetically related Lentzea species. Therefore, it is concluded that strain NX62T represents a novel species of the genus Lentzea, for which the name Lentzea isolaginshaensis sp. nov. is proposed. The type strain is NX62T (= CGMCC 4.7522T = KCTC 49179T).

Abstract
A non-motile, coccobacilli-shaped and yellow-coloured bacterium, designated strain SYSU D60003T, was isolated from a desert soil sample. Cells were Gram-stain-positive, catalase-negative and oxidase-positive. The whole cell hydrolysates contained ll-diaminopimelic acid as the diagnostic amino acid. The major fatty acids were C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and iso-C16 : 0. The respiratory menaquinones were MK-9(H8), MK-9(H4) and MK-9(H6). The DNA G+C content was determined to be 70.2 % (genome). The polar lipids detected were diphosphatidylglycerol, an unidentified glycolipid and seven unidentified polar lipids. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SYSU D60003T belonged to the order Acidimicrobiales (class Acidimicrobiia), but formed a clade closely linked to members of the genus Ilumatobacter. Data from a polyphasic taxonomy study suggested that the isolate represents a novel species of a novel genus in the order Acidimicrobiales, for which the name Desertimonas flava gen. nov., sp. nov. is proposed. The type strain of the proposed new taxon is SYSU D60003T (=KCTC 39917T=NBRC 112924T). Additionally, the new taxon along with the genus Ilumatobater (family unassigned) were distinctly separated from the related families Acidimicrobiaceae, Iamiaceae and 'Microtrichaceae' in the phylogenetic trees, besides presenting a unique 16S rRNA gene signature nucleotides. Therefore, we propose a new family Ilumatobacteraceae fam. nov. within the order Acidimicrobiales to accommodate members of these two genera.

Abstract
Strain SYSU D8008T was isolated from a desert sand sample collected from Saudi Arabia. The strain was observed to be Gram-stain positive, non-motile and aerobic. It can grow at 15-37 °C, pH 6.0-10.0 and can tolerant up to 7% (w/v) NaCl. Pairwise comparison of the 16S rRNA gene sequence indicated that strain SYSU D8008T shares high sequence similarities with Georgenia deserti SYSU D8004T (96.8%) and Georgenia halophila YIM 93316T (96.8%). Menaquinone MK-8(H4) was detected as the respiratory isoprenologue. The polar lipid profile of strain SYSU D8008T was found to consist of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two phosphatidylinositol mannosides, an unidentified glycolipid and an unidentified phospholipid. Strain SYSU D8008T was found to contain anteiso-C15:0 and iso-C15:0 as the predominant fatty acids. Galactose, glucose and rhamnose were detected as the whole cell sugars. Based on the phenotypic, genotypic and phylogenetic characteristics, strain SYSU D8008T can be differentiated from other closely related members of the genus Georgenia. The strain SYSU D8008T, therefore, is concluded to represent a novel species of the genus Georgenia, for which the name Georgenia alba sp. nov. is proposed. The type strain is SYSU D8008T (= CGMCC 1.15800T = KCTC 39988T).

Abstract
A Nocardia-like actinobacterial strain, designated YIM TG2190T, was isolated from rhizosphere soil of Psammosilene tunicoides collected from Gejiu, Yunnan province, China. The cells of strain YIM TG2190T were observed to be Gram-stain positive and non-motile. The strain forms extensively branched substrate mycelia that fragments into rod-shaped elements. The 16S rRNA gene sequence analysis showed that strain YIM TG2190T is closely related to Nocardia nova (97.5%), Nocardia jiangxiensis (97.1%) and Nocardia miyunensis (96.8%). Growth occurs at 4-30 °C (optimum 28 °C), pH 6.0-8.0 (optimum pH 7.0) and the strain can tolerate NaCl (w/v) up to 3% (optimum 0-1%). The cell walls were found to contain meso-diaminopimelic acid. The whole-cell sugars were identified as glucose, mannose, ribose, galactose, arabinose and fucose. The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol mannosides, phosphatidylglycerol and an unidentified phospholipid. The menaquinones detected were MK-9 (H2) and MK-8 (H4). The major fatty acids (> 5%) were found to be C16:0 (33.9%), summed feature 3 (21.7%), C18:0 10-methyl TBSA (13.7%) and C18:1ω9c (7.0%). The DNA G+C content was determined to be 61.1 mol%. DNA-DNA relatedness between the strain YIM TG2190T and N. nova CGMCC 4.1705T, N. jiangxiensis CGMCC 4.1905T and N. miyunensis CGMCC 4.1904T were 46.9 ± 2.6, 36.8 ± 1.3, and 35.7 ± 2.6%, respectively, values which are less than the threshold value (70%) for the delineation of prokaryotic genomic species. The phenotypic, chemotaxonomic and phylogenetic data indicates that strain YIM TG2190T represents a novel species of the genus Nocardia, for which the name Nocardia zhihengii sp. nov. is proposed. The type strain is YIM TG2190T (=KCTC 39596T = DSM 100515T).

Abstract
A Gram-stain-positive, aerobic, motile with peritrichous flagella, rod-shaped bacterium, designated CFH S0170T, was isolated from a soil sample collected from Catba island in Ha Long Bay, Hai Phong City, Vietnam. Comparison of the 16S rRNA gene sequences showed that strain CFH S0170T belonged to the genus Paenibacillus and showed closest relationship with Paenibacillus vulneris CCUG 53270T (98.1 % similarity). Phylogenetic analysis demonstrated that the novel candidate formed a coherent branch with P. vulneris CCUG 53270T and Paenibacillus yunnanensis YN2T. Furthermore, the novel strain shared 87.2 % rpoB gene sequence similarity with P. vulneris CCUG 53270T. Growth of strain CFH S0170T occurred at 10-40 °C, pH 6.0-8.0 and with 0-2.0 % (w/v) NaCl. Strain CFH S0170T contained mannose, glucose and rhamnose as the major whole-cell sugars. The cell-wall peptidoglycan contained meso-diaminopimelic acid, glutamic acid, lysine and aspartic acid. The polar lipid profile contained diphosphatidylglycerol, phosphatidylethanolamine, glycolipids and phospholipids. The dominant cellular fatty acids included anteiso-C15 : 0 and C15 : 0. The genomic DNA G+C content was 50.9 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic analysis, strain CFH S0170T is affiliated to the genus Paenibacillus, but could be distinguished from other valid species of this genus. It is concluded that strain CFH S0170T should be considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus esterisolvens sp. nov. is proposed. The type strain is CFH S0170T (=KCTC 33624T=BCRC 80802T).

Abstract
Strain SYSU D8004T was isolated from a sample collected from an arid area in Saudi Arabia. The isolate was Gram-stain-positive, non-motile, aerobic and non-spore-forming. It could grow at 4-45 °C, at pH 6.0-10.0 and in the presence of up to 17 % (w/v) NaCl. Pairwise comparison of the 16S rRNA gene sequences indicated that strain SYSU D8004T shared highest sequence similarity with Georgenia halophila YIM 93316T (96.5 %). Menaquinone MK-8(H4) was detected as the respiratory quinone. The polar lipid profile of strain SYSU D8004T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two phosphatidylinositol mannosides, two unidentified phospholipids and an unidentified glycolipid. Strain SYSU D8004T contained anteiso-C15 : 0, iso-C15 : 0 and C14 : 0 as the predominant fatty acids (>10 %). Galactose, glucose and rhamnose were detected as whole-cell sugars. Based on analyses of the phenotypic, genotypic and phylogenetic characteristics, it was determined that strain SYSU D8004T could be differentiated from other closely related members of the genus Georgenia. Strain SYSU D8004T is therefore considered to represent a novel species of the genus Georgenia, for which the name Georgenia deserti sp. nov. is proposed. The type strain is SYSU D8004T (=CGMCC 1.15793T=KCTC 39987T).

Abstract
Strains SYSU D8007T and SYSU D8014T were isolated from desert soil collected from Saudi Arabia. The two isolates were Gram-stain-positive, non-motile, aerobic and non-spore-forming. These strains were able to grow at 4-45 °C and in the presence of up to 8 % (w/v) NaCl. Strain SYSU D8007T could grow at pH 6.0-10.0, and strain SYSU D8014T at pH 5.0-10.0. They shared highest 16S rRNA gene sequence similarities with Microbacterium marinilacus YM11-607T and Microbacterium paludicola US15T. Menaquinones MK-11 and MK-12 were detected as the respiratory quinones. The polar lipid profiles of strains SYSU D8007T and SYSU D8014T consisted of diphosphatidylglycerol and phosphatidylglycerol, but differed in the number of unidentified glycolipids. Strain SYSU D8007T contained anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 as the predominant fatty acids, while strain SYSU D8014T contained anteiso-C15 : 0 and anteiso-C17 : 0 as the major fatty acids (>10 %). While glucose, rhamnose and ribose were detected in strain SYSU D8007T as the whole-cell sugars, galactose, glucose and rhamnose were present in strain SYSU D8014T. The genomic DNA G+C content of strains SYSU D8007T and SYSU D8014T was 72.2 and 73.6 mol%, respectively. Based on phenotypic, genotypic and phylogenetic characteristics, it can be concluded that strains SYSU D8007T and SYSU D8014T represent two novel species of the genus Microbacterium, for which the names Microbacterium album sp. nov. and Microbacterium deserti sp. nov. are proposed, respectively. The type strains are SYSU D8007T (=CGMCC 1.15794T=KCTC 39990T) and SYSU D8014T (=CPCC 204619T=KCTC39991T).

Abstract
Strain SYSU D8009T was isolated from a desert sample collected from Saudi Arabia. The taxonomic position of the isolate was investigated by a polyphasic approach. The novel isolate was Gram-stain-negative, non-motile, aerobic and non-spore-forming. It was able to grow at 4-45 °C and pH 4.0-8.0, and exhibited NaCl tolerance of up to 1.5 % (w/v). Strain SYSU D8009T shared the closest 16S rRNA gene sequence similarities with members of the family Acetobacteraceae, with a value of less than 96.0 %. In the phylogenetic dendrograms, the strain clustered with the genera Paracraurococcus, Craurococcus and Crenalkalicoccus within the family Acetobacteraceae but with a distinct lineage, thereby demonstrating that the strain should be classified within the family Acetobacteraceae. The respiratory ubiquinone was found to be Q-10. The polar lipids of the strain comprised diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and four unidentified aminolipids. The predominant cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The genomic DNA G+C content of strain SYSU D8009T was determined to be 71.6 mol%. Based on the results of the phylogenetic analyses and differences in the physiological and biochemical characteristics, strain SYSU D8009T merits representation of a novel species of a new genus within the family Acetobacteraceae, for which the name Siccirubricoccus deserti gen. nov., sp. nov. is proposed. The type strain of Siccirubricoccus deserti sp. nov. is SYSU D8009T (=CGMCC 1.15936T=KCTC 62088T).

Abstract
A novel actinobacterial strain, designated SYSU K10005T, was isolated from a soil sample collected from a karst cave in Xingyi county, Guizhou province, south-west China. The taxonomic position of the strain was investigated using a polyphasic approach. Cells of the strain were aerobic and Gram-stain-positive. On the basis of 16S rRNA gene sequence analysis, strain SYSU K10005T was most closely related to the type strains of the genus Nonomuraea, and shared highest sequence similarity of 98.4 % with Nonomuraea candida HMC10T. DNA-DNA hybridization values between the two strains were less than 70 %. The whole-cell hydrolysates of strain SYSU K10005T contained meso-diaminopimelic acid (diagnostic diamino acid), and arabinose, madurose and rhamnose (whole-cell sugars). The major isoprenoid quinone was MK-9(H4), while the major fatty acids were iso-C16 : 0, 10-methyl C17 : 0, C17 : 1ω8c and C17 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, hydroxyl-phosphatidylethanolamine, lyso-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, an unidentified lipid, two unidentified ninhydrin-positive phosphoglycolipids and two unidentified phospholipids. The genomic DNA G+C content of strain SYSU K10005T was 64.2 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU K10005T can be characterized to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea cavernae sp. nov. is proposed. The type strain is SYSU K10005T (=KCTC 39805T=CGMCC 4.7368T).
