Abstract
A Gram-stain-positive, rod-shaped, non-spore-forming and non-motile bacterium, designated WY-20T, was isolated from a lakeside soil sample collected in Jiangxi Province, PR China. Growth was observed at 20-42 °C (optimum 30 °C), pH 5.0-8.0 (optimum pH 7.0) and salinity of 0-3.0% (w/v; optimum 0.5%). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain WY-20T belongs to the genus Nocardioides and showed the highest sequence similarity (98.1%) to N. phosphati WYH11-7T, followed by N. cavernaquae K1W22B-1T (97.8%), N. marmoriterrae JOS5-1T (97.2%) and N. jensenii NBRC 14755T (97.1%). The average nucleotide identity and digital DNA-DNA hybridization values between strains WY-20T and N. phosphati WYH11-7T were 83.5% and 26.2%, respectively. The predominant fatty acids (≥ 10% of the total fatty acids) were C18:1ω9c, C17:0, C16:0, summed feature 8 (C18:1ω7c and/or C18: 1ω6c) and C17:1ω9c. The major menaquinone was MK-8 (H4). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and two unidentified phospholipids. In addition, meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Based on phenotypic, genotypic and phylogenetic pieces of evidence, strain WY-20T represents a novel species in the genus Nocardioides, for which the name Nocardioides jiangxiensis sp. nov. is proposed. The type strain is WY-20T (= GDMCC 4.317T = KACC 23379T).

Abstract
Three Gram-stain-positive, non-motile, short rod-shaped, catalase-positive and oxidase-negative actinomycete strains (SOB44T, SOB72T and SOB77T) were isolated from a deep-sea sediment sample collected from the Western Pacific Ocean. Cells of the three strains showed optimum growth at 30 °C and pH 7.0. Strains SOB44T, SOB72T and SOB77T could tolerate up to 10, 9 and 9 % (w/v) NaCl concentration and grow at pH 5.0-12.0, 5.0-11.0 and 5.0-11.0, respectively. Phylogenetic results based on 16S rRNA gene sequences showed that the three isolates belonged to the genus Nocardioides and were identified as representing three novel species based on 78.0-93.1 % average nucleotide identity and 21.3-50.0 % DNA-DNA hybridization values with closely related reference strains. Strains SOB44T, SOB72T and SOB77T showed highest 16S rRNA gene sequence similarity to Nocardioides salarius CL-Z59T (99.2 %), Nocardioides deserti SC8A-24T (99.2 %) and Nocardioides marmotae zg-579T (98.5 %), respectively. All three strains had MK-8(H4) as the respiratory quinone, iso-C16 : 0 as the major fatty acid, and phosphatidylglycerol, diphosphatidylglycerol and phosphatidylinositol as the major polar lipids. The diagnostic diamino acid in the cell-wall peptidoglycan of all three isolates was ll-diaminopimelic acid. The DNA G+C contents of strains SOB44T, SOB72T and SOB77T were 71.1, 72.9 and 72.9 mol%, respectively. Based on the phenotypic, phylogenetic and genotypic data, strains SOB44T, SOB72T and SOB77T clearly represent three novel taxa within the genus Nocardioides, for which the names Nocardioides cremeus sp. nov. (type strain SOB44T=JCM 35774T= MCCC M28400T), Nocardioides abyssi sp. nov. (type strain SOB72T=JCM 35775T=MCCC M28318T) and Nocardioides oceani sp. nov. (type strain SOB77T=JCM 35776T=MCCC M28544T) are proposed.

Abstract
Six Gram-stain-positive, aerobic and irregular-rod-shaped actinobacteria (ZJ1313T, ZJ1307, MC1495T, Y192, 603T and X2025) were isolated from the Qinghai-Tibet Plateau of China and were characterized using a polyphasic taxonomic method. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the six new strains formed three distinct clusters within the genus Nocardioides, and strains ZJ1313T and ZJ1307 were most closely related to N. solisilvae JCM 31492T (16S rRNA gene sequence similarity, 98.0 %), MC1495T and Y192 to N. houyundeii 78T (98.5 %), and 603T and X2025 to N. dokdonensis JCM 14815T (97.6 %). The digital DNA-DNA hybridization values of strains ZJ1313T, MC1495T and 603T among each other and with type strains of their closest relatives were all below the 70 % cut-off point, but values within each pair of new strains were all higher than the threshold. The major fatty acids of these strains were iso-C16 : 0, C17 : 1 ω8c or C18 : 1 ω9c. MK-8(H4) was the predominant respiratory menaquinone and ʟʟ-2,6-diaminopimelic acid was the diagnostic diamino acid. All the strains shared diphosphatidylglycerol (predominant), phosphatidylglycerol, phosphatidylcholine and phosphatidylinositol as the common polar lipids, with minor difference in the types of unidentified phospholipids, glycolipids and lipids. The G+C contents based on genomic DNA of strains ZJ1313T, MC1495T and 603T were 72.5, 72.1 and 73.2 mol%, respectively. The above results suggested that strain pairs ZJ1313T/ZJ1307, MC1495T/Y192 and 603T/X2025 represent three new species of genus Nocardioides, for which the names Nocardioides ochotonae sp. nov. (ZJ1313T=GDMCC 4.177T=KCTC 49537T=JCM 34185T), Nocardioides campestrisoli sp. nov. (MC1495T=GDMCC 4.176T=KCTC 49536T=JCM 34307T) and Nocardioides pantholopis sp. nov. (603T=CGMCC 4.7510T=DSM 106494T) are proposed accordingly.

Abstract
In the present study, four bacterial strains, two (S-713T and 406) isolated from faecal samples of Tibetan antelopes and the other two (S-531T and 1598) from leaves of dandelion collected on the Qinghai-Tibet Plateau of PR China, were analysed using a polyphasic approach. All four isolates were aerobic, rod-shaped, non-motile, oxidase-negative, Gram-stain-positive and catalase-positive. According to four phylogenetic trees, strain pairs S-713T/406 and S-531T/1598 form two independent branches belonging to the genus Nocardioides, and are closest to Nocardioides lianchengensis, Nocardioides dokdonensis, Nocardioides salarius, Nocardioides marinisabuli, Nocardioides psychrotolerans and Nocardioides szechwanensis. Although sharing MK8-(H4) as their major isoprenoid quinone, strains S-713T and S-531T contained C18 : 1 ω9c (24.64 and 16.34 %) and iso-C16 : 0 (9.74 and 29.38 %), respectively, as their main fatty acids, with remarkable differences in their biochemical profiles but only slight ones in their optimal growth conditions. The chromosomes of strains S-713T and S-531T were 4 207 844 bp (G+C content, 73.0 mol%) and 4 809 817 bp (G+C content, 72.5 mol%), respectively. Collectively, the two strain pairs represent two separate novel species of the genus Nocardioides, for which the names Nocardioides dongkuii sp. nov. and Nocardioides lijunqiniae sp. nov. are proposed, with S-713T (=JCM 33698T=CGMCC 4.7660T) and S-531T (=JCM 33468T=CGMCC 4.7659T) as the respective type strains.

Abstract
A Gram-stain positive, asporogenous, aerobic, white -coloured bacterium, designated 18JY15-6T, was isolated from soil from Jeju Island, Korea. Pairwise analysis of the 16S rRNA gene sequence of strain 18JY15-6T indicated high similarity to Nocardioides phosphati DSM 104026T (97.4%), Marmoricola terrae KACC 17308T (96.7%) and Nocardioides jensenii KCTC 0074BPT (96.6%). Phylogenetic analysis revealed that strain 18JY15-6T formed a distinct lineage within the family Nocardioidaceae and is closely related to members of the genus Nocardioides. Genome sequencing of strain 18JY15-6T revealed 3221 total genes, including 3162 protein coding genes, 59 RNA and 31 pseudogenes. Growth was observed at 18-37 °C (optimal 30 °C) in R2A medium at pH 7.0. The major cellular fatty acids of strain 18JY15-6T were identified as C16:0, C18:1ω9c, C18:0 10-methyl, tuberculostearic and C17:0. The fatty acid profile of strain 18JY15-6T was more dissimilar when compared with M. terrae. The only respiratory quinone present was found to be MK-8(H4). The major polar lipids are diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. The results of phylogenetic, biochemical and chemotaxonomic characterisation allow the differentiation of strain 18JY15-6T from N. phosphati WYH11-7T, M. terrae JOS5-1T and N. jensenii NBRC 14755T which supports the conclusion that this strain represents a novel species of the genus Nocardioides, for which we propose the name Nocardioides jejuensis sp. nov. The type strain of Nocardioides jejuensis is 18JY15-6T (= KCTC 49105T = JCM 33182T).

Abstract
The cultivation of microbial species remains a primary challenge in microbiology and obtaining pure cultures is essential for the study of microbial physiology and function. When isolating microorganisms from aquaculture environments, Vibrio are the most dominate isolates on the media that are commonly used. In order to expand our ability to study microbial species, an easy-operation and low-cost medium that can reduce the interference of Vibrio strains and increase the cultivability of other bacteria is urgently needed. We compared viable cell counts on conventional media (CM; including Marine Agar 2216 and LB media) and diluted media (DM; including 1/10-Marine Agar 2216, 1/10-LB). We also assessed the diversity of cultivable microorganisms under high and low nutrient conditions by a plate-wash strategy coupled with high-throughput sequencing of the V4 hypervariable region of the 16S rRNA gene. The results show that microbial communities from DM, especially 1/10-Marine Agar 2216, are more diverse than those obtained from CM. Vibrio isolates were reduced on DM. PICRUSt analysis revealed that nutrient composition is a significant contributor to the diversity and function of the cultivable microbial communities. Bacteria grown on CM possess more pathogenic characteristics, whereas DM favors the growth of bacteria that have multiple metabolic functions. Collectively, our data provide strong evidence that dilution of CM influences the cultivability of bacteria from aquaculture seawater. It also supports that DM can expand the range of microbial species that can be cultivated. This study also provides insights for media design in microbial cultivation from aquaculture systems.

Abstract
BACKGROUND Pontimonas salivibrio strain CL-TW6T (=KCCM 90105 = JCM18206) was characterized as the type strain of a new genus within the Actinobacterial family Microbacteriaceae. It was isolated from a coastal marine environment in which members of Microbactericeae have not been previously characterized. RESULTS The genome of P. salivibrio CL-TW6T was a single chromosome of 1,760,810 bp. Genomes of this small size are typically found in bacteria growing slowly in oligotrophic zones and said to be streamlined. Phylogenetic analysis showed it to represent a lineage originating in the Microbacteriaceae radiation occurring before the snowball Earth glaciations, and to have a closer relationship with some streamlined bacteria known through metagenomic data. Several genomic characteristics typical of streamlined bacteria are found: %G + C is lower than non-streamlined members of the phylum; there are a minimal number of rRNA and tRNA genes, fewer paralogs in most gene families, and only two sigma factors; there is a noticeable absence of some nonessential metabolic pathways, including polyketide synthesis and catabolism of some amino acids. There was no indication of any phage genes or plasmids, however, a system of active insertion elements was present. P. salivibrio appears to be unusual in having polyrhamnose-based cell wall oligosaccharides instead of mycolic acid or teichoic acid-based oligosaccharides. Oddly, it conducts sulfate assimilation apparently for sulfating cell wall components, but not for synthesizing amino acids. One gene family it has more of, rather than fewer of, are toxin/antitoxin systems, which are thought to down-regulate growth during nutrient deprivation or other stressful conditions. CONCLUSIONS Because of the relatively small number of paralogs and its relationship to the heavily characterized Mycobacterium tuberculosis, we were able to heavily annotate the genome of P. salivibrio CL-TW6T. Its streamlined status and relationship to streamlined metagenomic constructs makes it an important reference genome for study of the streamlining concept. The final evolutionary trajectory of CL-TW6 T was to adapt to growth in a non-oligotrophic coastal zone. To understand that adaptive process, we give a thorough accounting of gene content, contrasting with both oligotrophic streamlined bacteria and large genome bacteria, and distinguishing between genes derived by vertical and horizontal descent.

Abstract
A novel actinobacterial strain, designated NCCP-696T, was isolated from the Thal desert in Punjab, Pakistan, and characterized by using a polyphasic taxonomy approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NCCP-696T belongs to the genus Nocardioides and showed the highest level of sequence similarity with respect to Nocardioides panacisoliGsoil 346T (98.2 %) and less than 96.4 % to the strains of other species of the genus Nocardioides. Cells of strain NCCP-696T were Gram-positive, aerobic, non-motile rods and formed cream-coloured colonies. The strain was positive for oxidase and catalase. Growth occurred at 20-42 °C (optimum 30-37 °C) at pH 5.5-9.0 (optimum pH 7.0) and with 0-4 % NaCl (optimum 0-2 %, w/v). Strain NCCP-696T contained Iso-C16 : 0, C18 : 1ω9c, C17 : 1ω8c and C17 : 0 as the predominant fatty acids and was found to have LL-2,6-diaminopimelic acid in the cell-wall peptidoglycan. The polar lipid profile consisted of phosphatidylinositol, phosphatidylglycerol and one unknown phospholipid. The major menaquinone was MK-8(H4) (98.7 %) while a minor amount (1.3 %) of MK-9(H2) was also detected. The DNA G+C content of the genomic DNA was 71.6 mol%. The DNA-DNA hybridization value of the isolate against the closely related type strain Nocardioides panacisoliGsoil 346T was 56.3±1.4. On the basis of the phylogenetic inference, chemotaxonomic characteristics and phenotypic data, strain NCCP-696T should be classified as a novel species, for which the name Nocardioides thalensis sp. nov. is proposed. The type strain is NCCP-696T (=DSM 103833T=CCTCC AB 2016296T).

Abstract
A Gram-staining positive, non-spore forming, non-pigmented and non-motile bacterium, designated as NCCP-1340(T), was isolated from a hot water spring, Tatta Pani, Pakistan. Cells of strain NCCP-1340(T) were observed to be aerobic, rod shaped, catalase and urease positive but H2S production and oxidase negative. Growth was observed at pH 6.0-8.0 (optimum pH 7.0) and at 20-40 °C (optimum 37 °C). The strain could tolerate 0-8 % NaCl (optimum 2 %, w/v). Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain NCCP-1340(T) belongs to the genus Nocardioides and is closely related to Nocardioides iriomotensis JCM 17985(T) (96.8 %), Nocardioides daedukensis KCTC 19601(T) (96.6 %), Nocardioides jensenii KCTC 9134(T) (96.1 %) and Nocardioides daejeonensis KCTC 19772(T) (96.1 %). The DNA-DNA relatedness values of strain NCCP-1340(T) with N. iriomotensis JCM 17985(T), N. daedukensis KCTC 19601(T) and N. jensenii KCTC 9134(T) were found to be less than 53 %. The DNA G+C content of strain NCCP-1340(T) was determined to be 71.8 mol %. The affiliation of strain NCCP-1340(T) to the genus Nocardioides was further supported by chemotaxonomic data which showed the presence of MK-8(H4) as major menaquinone system; iso-C16:0, C17:0, C16:0 10-methyl, iso-C15:0 and C 15:0 as major cellular fatty acids; and diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and unidentified glycolipids and polar lipids in the polar lipids profile. The cell wall peptidoglycan contained LL-diaminopimelic acid as the diagnostic amino acid. On the basis of physiological and biochemical characteristics and the phylogenetic analyses, strain NCCP-1340(T) can be distinguished from the closely related taxa and thus represents a novel species of the genus Nocardioides, for which the name Nocardioides pakistanensis sp. nov. is proposed with the type strain NCCP-1340(T) (= DSM 29942(T) = JCM 30630(T)).

Abstract
A Gram-stain-positive, non-motile, strictly aerobic, non-spore-forming and short rod-shaped bacterial strain, CL-GY44T, was isolated from coastal seawater, Korea. Analysis of the 16S rRNA gene sequence of strain CL-GY44T revealed a clear affiliation with the genus
Nocardioides
. Based on phylogenetic analysis, strain CL-GY44T showed the closest phylogenetic relationship with
Nocardioides ginsengagri
BX5-10T and
Nocardioides plantarum
NCIMB 12834T. Strain CL-GY44T was not able to grow in the presence of NaCl but grew with 0–5.5 % sea salts. The optimum temperature and pH for growth were 30 °C and pH 7.0. The major cellular fatty acids of strain CL-GY44T were C17 : 1ω6c, iso-C16 : 0, C16 : 0 and iso-C15 : 0 and the major menaquinone was MK-8(H4). The cell-wall analysis showed that strain CL-GY44T contained ll-diaminopimelic acid. The genomic DNA G+C content was 71.6 mol%. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain CL-GY44T could be clearly distinguished from members of the genus
Nocardioides
. Thus, strain CL-GY44T should be classified as representing a novel species in the genus
Nocardioides
, for which the name Nocardioides marinquilinus sp. nov. is proposed. The type strain is CL-GY44T ( = KCCM 90109T = JCM 18459T).

Abstract
A Gram-staining-negative, non-motile, spore-forming, rod-shaped, marine bacterial strain, CL-KR2(T), was isolated from tropical seawater near Kosrae, an island in the Federated States of Micronesia. Analysis of the 16S rRNA gene sequence of strain CL-KR2(T) revealed a clear affiliation with the genus Gracilimonas. Based on phylogenetic analysis, strain CL-KR2(T) showed the closest phylogenetic relationship to Gracilimonas tropica CL-CB462(T), with 16S rRNA gene sequence similarity of 96.6 %. DNA-DNA relatedness between strain CL-KR2(T) and G. tropica CL-CB462(T) was 6.7 % (reciprocal 9.5 %). Strain CL-KR2(T) grew in the presence of 1-20 % sea salts and the optimal salt concentration was 3.5-5 %. The temperature and pH optima for growth were 35 °C and pH 7.5. The major cellular fatty acids (≥10.0 %) of strain CL-KR2(T) were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) and iso-C17 : 1ω9c and the only isoprenoid quinone was MK-7. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unidentified phospholipid, two unidentified glycolipids and two unidentified lipids. The genomic DNA G+C content of strain CL-KR2(T) was 43.2 mol%. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain CL-KR2(T) could be distinguished from the only member of the genus Gracilimonas with a validly published name. Thus, strain CL-KR2(T) should be assigned to a novel species in the genus Gracilimonas, for which the name Gracilimonas rosea sp. nov. is proposed. The type strain is CL-KR2(T) ( = KCCM 90206(T) = JCM 18898(T)).

Abstract
Two Gram-positive, rod-shaped, non-spore-forming bacteria (strains RHLT1-17T and RHLT2-1T) were isolated from Hailuogou glacier in Szechwan province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the strains belonged to the genus
Nocardioides
and shared 97.8 % sequence similarity with each other and 97.6 and 98.4 % sequence similarity, respectively, with
Nocardioides kribbensis
KSL-2T. Strain RHLT1-17T grew at 0–35 °C and strain RHLT2-1T grew at 0–25 °C. The major cellular fatty acids of strain RHLT1-17T were C17 : 1ω8c (32.69 %) and iso-C16 : 0 (21.74 %). The major cellular fatty acids of strain RHLT2-1T were C18 : 1ω9c (28.72 %), summed feature 3 (17.14 %; comprising C16 : 1ω7c and/or C16 : 1ω6c), iso-C16 : 0 (14.35 %), C16 : 0 (9.96 %) and iso-C14 : 0 (8.34 %). Both strains contained ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan and MK-8(H4) as the predominant menaquinone. On the basis of data obtained using a polyphasic approach, two novel species, Nocardioides szechwanensis sp. nov. (type strain RHLT1-17T = CGMCC 1.11147T = NBRC 108562T) and Nocardioides psychrotolerans sp. nov. (type strain RHLT2-1T = CGMCC 1.11156T = NBRC 108563T), are proposed.

N. salarius
,
N. marinisabuli
,
N. basaltis
and
N. dokdonensis
. The chemotaxonomic properties of strain D94-1T were consistent with those of the genus
Nocardioides
: the cell-wall peptidoglycan type was based on ll-diaminopimelic acid, the predominant menaquinone was MK-8(H4) and the major fatty acids were iso-C16 : 0 (29.15 %) and anteiso-C17 : 0 (21.0 %). The DNA G+C content was 71.8 mol%. On the basis of the evidence presented in this study, strain D94-1T represents a novel species of the genus
Nocardioides
, for which the name Nocardioides lianchengensis sp. nov. is proposed. The type strain is D94-1T ( = DSM 24663T = CGMCC 4.6858T).

Abstract
The taxonomic relationship between Nocardioides salarius CL-Z59(T) and Nocardioides basaltis J112(T) was established. The 16S rRNA gene sequences of the type strains showed 99.6 % similarity. The ΔT(m) for genomic DNA-DNA hybridization of N. salarius CL-Z59(T) and N. basaltis J112(T) was 0.6-1.6 °C, indicating that both strains belong to a single species. Phenotypic and chemotaxonomic characteristics showed no pronounced differences between the two species. Based on the results of the polyphasic approach, it is proposed that N. basaltis J112(T) is a later heterotypic synonym of N. salarius CL-Z59(T). An emended description of the species N. salarius is given.

Abstract
A Gram-positive, non-motile, rod-shaped, psychrophilic actinomycete, designated strain Cr7-14T, was isolated from alpine glacier cryoconite. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Cr7-14T was related to members of the genus Nocardioides and shared highest 16S rRNA gene sequence similarities with the type strains of Nocardioides furvisabuli (98.6 %), Nocardioides ganghwensis (98.2 %), Nocardioides oleivorans (98.1 %) and Nocardioides exalbidus (97.6 %). The predominant cellular fatty acids of strain Cr7-14T were C17 : 1ω8c (39.5 %) and iso-C16 : 0 (32.4 %). The major menaquinone was MK-8(H4). The diagnostic diamino acid in the cell-wall peptidoglycan was ll-2,6-diaminopimelic acid. The predominant cell-wall sugars were galactose and rhamnose. The polar lipid pattern contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol, four unknown glycolipids and two unknown polar lipids. The genomic DNA G+C content was 71.9 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness data, a novel species, Nocardioides alpinus sp. nov., is proposed, with Cr7-14T ( = DSM 23325T = LMG 26053T = CGMCC 1.10697T) as the type strain.

Abstract
A Gram-positive, rod-shaped, non-spore-forming bacterium (Gsoil 485(T)) was isolated from the soil of a ginseng field located in Pocheon province in South Korea. This bacterium was characterized in order to determine its taxonomic position by using the polyphasic approach. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 485(T) was shown to belong to the family Nocardioidaceae and related to Nocardioides koreensis (96.8% 16S rRNA gene sequence similarity), Nocardioides basaltis (96.7%), Nocardioides salarius (96.7%), and Nocardioides sediminis (96.5%). The sequence similarity with other species that had validly published names within the genus Nocardioides was less than 96.4%. Strain Gsoil 485(T) was characterized chemotaxonomically as having LL-2,6-diaminopimelic acid in a cell-wall peptidoglycan, MK-8(H(4)) as the predominant menaquinone, and iso-C(16:0), C(18:1) ω9c as the major fatty acids. The G+C content of genomic DNA was 71.6 mol%. The chemotaxonomic properties and phenotypic characteristics supported the affiliation of strain Gsoil 485(T) to the genus Nocardioides. The results of both physiological and biochemical tests allowed for genotypic differentiation of strain Gsoil 485(T) from the recognized Nocardioides species. Therefore, strain Gsoil 485(T) is considered to represent the novel species, for which the name Nocardioides ginsengisegetis sp. nov. is proposed, with the type strain Gsoil 485(T) (KACC 14269(T) =KCTC 19469(T) =DSM 21349(T)).

Abstract
A short coccoid- to rod-shaped, motile, mesophilic actinobacterium, strain MSL-22T, was isolated from soil on Bigeum Island, Korea. A polyphasic study was undertaken to establish the taxonomic position of this strain. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MSL-22T formed an evolutionary lineage within the radiation of the genus Nocardioides. In particular, it formed a monophyletic lineage with Nocardioides jensenii KCTC 9134T with which it shared the highest sequence similarity of about 97.3%. However, DNA–DNA relatedness demonstrated that strain MSL-22T was distinct from its closest phylogenetic neighbours. The cell-wall peptidoglycan of strain MSL-22T contained ll-diaminopimelic acid. The predominant menaquinone was MK-8(H4). Strain MSL-22T had a cellular fatty acid profile containing straight-chain, branched, unsaturated and 10-methyl fatty acids, with iso-C16 : 0 as the major fatty acid. The DNA G+C content of the strain was 68.7 mol%. On the basis of phenotypic and phylogenetic evidence, the strain is separate from previously described members of the genus Nocardioides and represents a novel species in this genus, for which the name Nocardioides mesophilus sp. nov. is proposed. The type strain is MSL-22T (=DSM 19432T=KCTC 19310T).

Abstract
A Gram-positive, rod-shaped, non-spore-forming bacterium (Gsoil 346T) was isolated from the soil of a ginseng field in South Korea and was characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequences, strain Gsoil 346T was shown to belong to the genus Nocardioides in the family Nocardioidaceae, with the most closely related species being Nocardioides aquiterrae GW-9T (96.6 % 16S rRNA gene sequence similarity); however, the strain clustered in a distinct branch of the phylogenetic tree with Nocardioides kongjuensis A2-4T (96.2 %), Nocardioides aromaticivorans H-1T (96.1 %), Nocardioides nitrophenolicus NSP41T (96.1 %) and Nocardioides simplex ATCC 15799T (95.9 %). Strain Gsoil 346T was characterized chemotaxonomically and found to have ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, phosphatidylinositol and phosphatidylglycerol as the major polar lipids, MK-8(H4) as the predominant menaquinone and iso-C16 : 0, C18 : 1
ω9c and C17 : 1
ω8c as the major fatty acids. The G+C content of the genomic DNA of the novel strain was 73.0 mol%. These chemotaxonomic properties supported the placement of strain Gsoil 346T in the genus Nocardioides. The results of physiological and biochemical tests, along with the phylogenetic analysis, allowed strain Gsoil 346T to be differentiated genotypically and phenotypically from recognized species of the genus Nocardioides. Therefore, strain Gsoil 346T represents a novel species, for which the name Nocardioides panacisoli sp. nov. is proposed, with Gsoil 346T (=KCTC 19470T=DSM 21348T) as the type strain.
