Abstract
A yellow pigmented, Gram-stain-positive, motile, facultatively anaerobic and irregular rod-shaped bacteria (strain M0-14T) was isolated from a till sample collected from the foreland of a high Arctic glacier near the settlement of Ny-Ålesund in the Svalbard Archipelago, Norway. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that M0-14T formed a lineage within the family Cellulomonadaceae, suborder Micrococcineae. M0-14T represented a novel member of the genus Pengzhenrongella and had highest 16S rRNA gene sequence similarity to Pengzhenrongella sicca LRZ-2T (97.3 %). Growth occurred at 4-25 °C (optimum 4-18 °C), at pH 6.0-9.0 (optimum pH 7.0), and in the presence of 0-5 % (w/v) NaCl. The predominant menaquinone was MK-9(H4) and the major fatty acids were anteiso-C15 : 0, C16 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). The major polar lipids were phosphatidylglycerol, phosphatidylinositol mannosides, phosphatidylinositol, one undefined phospholipid and five undefined phosphoglycolipids. The cell-wall diamino acid was l-ornithine whereas rhamnose and mannose were the cell-wall sugars. Polyphosphate particles were found inside the cells of M0-14T. Polyphosphate kinase and polyphosphate-dependent glucokinase genes were detected during genomic sequencing of M0-14. In addition, the complete pstSCAB gene cluster and phnCDE synthesis genes, which are important for the uptake and transport of phosphorus in cells, were annotated in the genomic data. According to the genomic data, M0-14T has a metabolic pathway related to phosphorus accumulation. The DNA G+C content of the genomic DNA was 70.8 %. On the basis of its phylogenetic relationship, phenotypic properties and chemotaxonomic distinctiveness, strain M0-14T represents a novel species of the genus Pengzhenrongella, for which the name Pengzhenrongella phosphoraccumulans sp. nov. is proposed. The type strain is M0-14T (= CCTCC AB 2012967T = NRRL B-59105T).

Abstract
Two novel strains were isolated from wetland soils in Goyang, Republic of Korea. The two Gram-stain-positive, facultatively anaerobic, rod-shaped bacterial-type strains were designated MW4T and MW9T. Phylogenomic analysis based on whole-genome sequences suggested that both strains belonged to the genus Cellulomonas. The cells of strain MW4T were non-motile and grew at 20-40 °C (optimum, 35 °C), at pH 6.0-10.0 (optimum, pH 8.0) and in the presence of 0-1.0% NaCl (optimum, 0 %). The cells of strain MW9T were non-motile and grew at 20-40 °C (optimum, 35 °C), at pH 5.0-9.0 (optimum, pH 8.0) and in the presence of 0-1.0% NaCl (optimum, 0 %). The average nucleotide identity (77.1-88.1 %) and digital DNA-DNA hybridization values (21.0-34.8 %) between the two novel strains and with their closely related strains fell within the range for the genus Cellulomonas. The novel strains MW4T and MW9T and reference strains possessed alkane synthesis gene clusters (oleA, oleB, oleC and oleD). Phylogenomic, phylogenetic, average nucleotide identity, digital DNA-DNA hybridization, physiological and biochemical data indicated that the novel strains were distinct from other members of the family Cellulomonadaceae. We propose the names Cellulomonas alba sp. nov. (type strain MW4T=KACC 23260T=TBRC 17645T) and Cellulomons edaphi sp. nov. (type strain MW9T=KACC 23261T=TBRC 17646T) for the two strains.

Abstract
A novel Gram-positive, aerobic, rod-shaped, non-motile, endospore-forming salt-tolerant bacterium strain (80T), was isolated from woodland soil collected near Kanas lake in the Altay region of Xinjiang, PR China. The strain grew at 15-45 °C, pH6.0-9.0 and with 0-14 % (w/v) NaCl. The complete genome size of the novel strain was 4 031 766 bp including a circle chromosome and a circle plasmid. The genomic DNA G+C content was 38.99 mol %. Phylogenetic analysis based on 16S rRNA gene sequence and genome showed that strain 80T has the highest similarity to Radiobacillus deserti TKL69T. However, the novel strain showed an average nucleotide identity value of 78.65 % (lower than 95 %) and a digital DNA-DNA hybridization value of 22.30 % with R. deserti TKL69T based on the genome sequences. The major fatty acids were anteiso-C15 : 0, iso-C15 : 0, anteiso-C17:0 and C16 : 1 ω7c alcohol. The only respiratory quinone was MK-7. The cell wall peptidoglycan was meso-diaminopimelic acid. Diphosphatidylglycerol, phosphatidylglycerol, one unidentified phospholipid, one unidentified aminophospholipid and two unidentified glycolipids were identified as the major polar lipids. The phylogenetic, phenotypic and chemotaxonomic analyses showed that strain 80T represents a novel species of the genus Radiobacillus and the name Radiobacillus kanasensis sp. nov. is proposed. The type strain is 80T (=GDMCC 1.2844T=JCM 35077T).

Abstract
Six Gram-stain-positive, aerobic or facultative anaerobic, catalase-positive, urease- and oxidase-negative, rod-shaped bacteria (zg-ZUI157T/zg-ZUI40, zg-ZUI222T/zg-ZUI199 and zg-ZUI188T/ zg-ZUI168) were characterized by a polyphasic approach. Optimal growth of the six strains was observed at pH 7.0 and 28 °C. Phylogenetic analyses based on the 16S rRNA gene and 247 core genes revealed that they belong to genus
Cellulomonas
. The three type strains have low digital DNA-DNA hybridization (19.3–30.1%) and average nucleotide identity values (78.0-85.5%) with all available genomes in the genus
Cellulomonas
, and a DNA G+C content range of 73.0-74.6 mol%. The major fatty acids detected in strain pairs zg-ZUI157T/zg-ZUI40 and zg-ZUI 222T/zg-ZUI199 were C16:0, anteiso-C15:0 and anteiso A-C15:1, and C16:0, anteiso-C15:0, anteiso A-C15:1 and anteiso-C17:0 in strain pair zg-ZUI188T/zg-ZUI168. Diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol mannosides were the major polar lipids detected in the three novel species. MK-9(H4) was the predominant quinone detected in strains zg-ZUI222T (87.4 %) and zg-ZUI188T (91.4 %), and MK-9(H4) (49.1 %) and MK-8 (43.4 %) in strain zg-ZUI157T. The cell-wall sugars detected in the three novel species mainly contained rhamnose. The cell-wall peptidoglycan type of the three novel species was A4β, with an inferred l-Orn–d-Asp interpeptide bridge for strains zg-ZUI157T and zg-ZUI222T, and l-Orn–d-Glu for strain zg-ZUI188T. Based on the results of the phenotypic, phylogenetic, genomic hybridization, average nucleotide identity and chemotaxonomic analyses, the six strains should be classified as belonging to three novel
Cellulomonas
species, for which the names Cellulomonas dongxiuzhuiae sp. nov. (zg-ZUI157T=GDMCC 1.2559T=KCTC 49678T), Cellulomonas wangleii sp. nov. (zg-ZUI222T=GDMCC 1.2501T=KCTC 49675T) and Cellulomonas fengjieae sp. nov. (zg-ZUI188T=GDMCC 1.2563T=KCTC 49674T) are proposed.

Chitin-Active Lytic Polysaccharide Monooxygenases Are Rare in Cellulomonas Species. Appl Environ Microbiol 2022; 88:e0096822.

Abstract
Cellulomonas flavigena is a saprotrophic bacterium that encodes, within its genome, four predicted lytic polysaccharide monooxygenases (LPMOs) from Auxiliary Activity family 10 (AA10). We showed previously that three of these cleave the plant polysaccharide cellulose by oxidation at carbon-1 (J. Li, L. Solhi, E.D. Goddard-Borger, Y. Mattieu et al., Biotechnol Biofuels 14:29, 2021, https://doi.org/10.1186/s13068-020-01860-3). Here, we present the biochemical characterization of the fourth C. flavigena AA10 member (CflaLPMO10D) as a chitin-active LPMO. Both the full-length CflaLPMO10D-Carbohydrate-Binding Module family 2 (CBM2) and catalytic module-only proteins were produced in Escherichia coli using the native general secretory (Sec) signal peptide. To quantify chitinolytic activity, we developed a high-performance anion-exchange chromatography-pulsed amperometric detection (HPAEC-PAD) method as an alternative to the established hydrophilic interaction liquid ion chromatography coupled with UV detection (HILIC-UV) method for separation and detection of released oxidized chito-oligosaccharides. Using this method, we demonstrated that CflaLPMO10D is strictly active on the β-allomorph of chitin, with optimal activity at pH 5 to 6 and a preference for ascorbic acid as the reducing agent. We also demonstrated the importance of the CBM2 member for both mediating enzyme localization to substrates and prolonging LPMO activity. Together with previous work, the present study defines the distinct substrate specificities of the suite of C. flavigena AA10 members. Notably, a cross-genome survey of AA10 members indicated that chitinolytic LPMOs are, in fact, rare among Cellulomonas bacteria. IMPORTANCE Species from the genus Cellulomonas have a long history of study due to their roles in biomass recycling in nature and corresponding potential as sources of enzymes for biotechnological applications. Although Cellulomonas species are more commonly associated with the cleavage and utilization of plant cell wall polysaccharides, here, we show that C. flavigena produces a unique lytic polysaccharide monooxygenase with activity on β-chitin, which is found, for example, in arthropods. The limited distribution of orthologous chitinolytic LPMOs suggests adaptation of individual cellulomonads to specific nutrient niches present in soil ecosystems. This research provides new insight into the biochemical specificity of LPMOs in Cellulomonas species and related bacteria, and it raises new questions about the physiological function of these enzymes.

Abstract
Two lactic acid bacterial strains (IMAU80584T and IMAU92037) were isolated from naturally fermented dairy products (kurut and yoghurt) in China and Russia. Based on sequence analysis of the 16S rRNA gene it was revealed that these strains belonged to
Lentilactobacillus rapi
. However, phylogenetic tree analyses of two housekeeping genes, rpoA (encoding RNA polymerase alpha subunit) and pheS (encoding phenylalanyl-tRNA synthase alpha subunit), and 88 core genes, indicated the two strains were separated into an independent monophyletic branch from
L. rapi
DSM 19907T, forming an infra-specific subgroup. The average nucleotide identity and digital DNA–DNA hybridization values between IMAU80584T and
L. rapi
DSM 19907T were 93.1 and 52.8 %, respectively. Strains IMAU80584T and IMAU92037 are distinguished from
L. rapi
DSM 19907T because they have different polar lipids and fatty acids. The novel subgroup strains could not ferment gluconate potassium. The DNA G+C content of strain IMAU80584T was 42.3 mol%. The major cellular fatty acids were C16 : 0, C18 : 1
ω9t and summed feature 5 (C18 : 0 ante and/or C18 : 2
ω6c and/or C18 : 2
ω9c). Therefore, based on the results of polyphasic taxonomic analysis, IMAU80584T and IMAU92037 could be considered as a novel subspecies in the species
L. rapi
with the proposed name
Lentilactobacillus rapi
subsp. dabitei subsp. nov. The type strain is IMAU80584T (=GDMCC 1.2566T=JCM 34647T).

Abstract
A bacterial strain, designated TRM 80801T, was isolated from the Karelinea in Taklamakan desert, Xinjiang Uygur Autonomous Region, north-west China. Cells were Gram-stain-positive, aerobic, non-motile, short rods. Strain TRM 80801T grew at 4-50 °C, with optimum growth at 28 °C, and grew at pH 6.0-11.0 and 1-15 % (w/v) NaCl. Phylogenetic analyses of the 16S rRNA gene sequences placed strain TRM 80801T within the genus Microbacterium with the highest similarities to Microbacterium suaedae YZYP 306T (98.97 %) and Microbacterium indicum BBH6T (98.17 %), respectively. The DNA G+C content of TRM 80801T is 69.38 mol%. The cell-wall peptidoglycan contained the amino acids ornithine, glutamic acid, glycine and alanine, the diagnostic diamino acid was ornithine. The acyl type of the peptidoglycan was glycolyl. Whole-cell sugars were ribose, mannose, glucose, rhamnose and galactose. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The predominant menaquinones were MK-10, MK-11 and MK-12. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol. The whole-genome average nucleotide identity (ANI) value between strain TRM 80801T and Microbacterium suaedae YZYP 306T is 70.2 %. On the basis of the evidence presented in this study, strain TRM 80801T is representative of a novel species in the genus Microbacterium, for which the name Microbacterium karelineae sp. nov. is proposed. The type strain is TRM 80801T (=CCTCC AB 2019248T=KCTC 49357T).

Abstract
A Gram-positive, smooth, sub-transparent, faint yellow,0.5-0.7 µm diameter, rod shaped aerobic or facultative aerobic strain P40-2Twas isolated from livestock farms in Northeast China. Strain P40-2T grew at 25-40 °C (optimum 30-38 °C), and in 0-4% (w/v) NaCl (optimum 0%) in LB medium. Based on 16S rRNA gene sequence analysis, strain P40-2T belongs to the class Cellulomonas and is most closely related to C. denverensis strain W6929, C. pakistanensis strain NCCP-11and C. hominis strain CE40.DNA-DNA hybridization rate of strain P40-2T was 29%, and the ANI with C.denverensisstrainW6929 was 85.33%. The genome is 3437431 bp long with a G + C content of 71.99%. Of the 3177 predicted genes, 3119 were protein-coding genes and 58 were RNA encoding genes. The chemotaxonomic data: menaquinone was MK-9(H4), anteiso-C15: 0, C16:0 and anteiso-C17: 0 were the major cellular fatty acids, and the main cell-wall amino acids were ornithine,alanine, glycine and glutamate. The cell wall peptidogly can sugars included glucose, rhamnose, galactose and mannose. The polar lipid present were DPG, PG, PE, and PIM. On the basis of DNA-DNA relatedness, phylogenetic position, complete genome sequence and physiological characteristics, strain P40-2T can be differentiated from other species of the genus Cellulomonas with validly published names and thus represents a novel species, for which the name Cellulomonas taurus is proposed. The type strain is Cellulomonas taurus P40-2T (= CGMCC No.1.17732T).The acute toxicity test in mice showed that LD50 of strain P40-2T was rather high with 1.5 × 1011 CFU/mouse, which indicated low pathogenicity. Drug susceptibility showed that strainP40-2T was resistant to most antibiotics and only sensitive to six antibiotics. Strain P40-2T contained a variety of hydrolytic enzymes including the ability to hydrolyze cellulose, β-glucan, chitin, xylan, and casein. Microbial flocculant MBF-P40 for sewage was prepared with strain P40-2T, after strain P40-2T was confirmed that had good flocculation effect. MBF-P40 was used to prepare flocculation rate of 99.40%. MBF-P40 treatmented sewage from eight different sources. Flocculation rate for pig farm wastewater was 96.07%, COD removal rate is 71.05%, ammonia nitrogen removal rate is 18.22%. The result shows that MBF-P40 has a good flocculation effect, and good prospect of development and application for wastewater treatment.

Abstract
A novel Gram-stain-positive, yellow, short-rod-shaped or coccoid bacterial strain, W204T, was isolated from a soil sample collected from Jiadengyu national forest park in China and characterized using a polyphasic approach. The cell-wall peptidoglycan contained ornithine as the diagnostic diamino acid. 16S rRNA gene sequence analysis indicated that strain W204T was closely related to Ornithinimicrobium flavum CPCC 203535T (97.4 %, similarity), Serinicoccus profundi CGMCC 4.5582T (96.9 %), Serinicoccus sediminis GP-T3-3T (96.8 %), Serinicoccus hydrothermalis JLT9T (96.7 %), Ornithinimicrobium cerasi CPCC 203383T (96.6 %) and Ornithinimicrobium kibberense K22-20T (96.6 %). However, the digital DNA-DNA genome hybridization value between strain W204T and the closest related strain O. flavum CPCC 203535T was 21.90 %. Complete genome analyses revealed that the size of the genome was 3.54 Mb and the genomic DNA G+C content was 70.79 mol%. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, an unidentified glycolipid, an unidentified phospholipid and an unidentified lipid. The major menaquinone was MK-8(H4). The predominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and C16 : 0. The phenotypic, chemotaxonomic and phylogenetic data suggested that strain W204T should be classified as representative of a novel species of the genus Ornithinimicrobium, for which the name Ornithinimicrobium pratense sp. nov. is proposed. The type strain is W204T (=GDMCC 1.1391T=KCTC 49237T).

Abstract
Two Gram-stain-positive, facultatively anaerobic, motile, aerobic, rod-shaped and non-spore-forming actinobacteria, strains AO-9T and AO-18, were isolated from paddy soil collected from Daejeon, Republic of Korea. Colonies were smooth, lemon-yellow and circular and 0.5-0.8×2.0-2.4 µm in diameter after 3 days of incubation at 28 °C on tryptic soy agar. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains AO-9T and AO-18 belonged to the genus Cellulomonas, showing the highest sequence similarities to Cellulomonas marina FXJ8.089T (96.6 %), Cellulomonas endophytica SYSUP0004T (96.5 %), Cellulomonas gelida DSM 20111T (96.2 %), Cellulomonas uda DSM 20107T (96.1 %), Cellulomonas rhizosphaerae NEAU-TCZ24T (96.1 %), Cellulomonas composti TR7-06T (96.0 %), Cellulomonas persica JCM 18111T (96.0 %) and less than 96 % to other closely related species. The DNA-DNA hybridization values between strains AO-9T and AO-18 were 87 %. The average nucleotide identity and digital DNA-DNA hybridization values between strain AO-9T and type strains of related species of the genus Cellulomonas were 84.0-85.8 % and 20.3-20.9 %, respectively. The major cellular fatty acids are anteiso-C15:0 (49.9 %), C14:0 (12.9 %) and iso-C14:0 (12.1 %). The predominant isoprenoid quinone was MK-9 (H4). The polar lipid profile consists of diphosphatidylglycerol, phosphatidylglycerol and one unidentified lipid. The DNA G+C content was 72.9 mol%. Based on its distinctive phenotypic, phylogenetic and chemotaxonomic characteristics, the two strains are considered to represent novel species of the genus Cellulomonas, for which the name Cellulomonas citrea sp. nov. is proposed. The type strain is AO-9T (=KACC 19069T=NBRC 112523T).

Abstract
Two Gram-stain-positive, catalase-positive and oxidase-negative, aerobic, non-motile, cellobiose-utilizing, short-rod-shaped strains (Z28T and Z29) were isolated from faeces of Tibetan antelope (Pantholops hodgsonii) collected on the Qinghai-Tibet Plateau. Strain Z28T shared 98.1, 98.0, 97.8 and 97.4 % 16S rRNA gene similarity, 24.1, 22.8, 23.2 and 26.3 % digital DNA-DNA hybridization relatedness and 80.8, 80.0, 80.7 and 80.9 % average nucleotide identity values with Cellulomonas oligotrophica DSM 24482T, Cellulomonas flavigena DSM 20109T, Cellulomonas iranensis DSM 14785T and Cellulomonas terrae JCM 14899T, respectively. Results from further phylogenetic analyses based on the 16S rRNA gene and 148 core genes indicated that strains Z28T and Z29 were closest to C. oligotrophica DSM 24482T and C. flavigena DSM 20109T, but clearly separated from the currently recognized species of the genus Cellulomonas. The genomic DNA G+C content of strain Z28T was 75.3 mol%. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C15 : 1 A, C16 : 0 and anteiso-C17 : 0. Ribose and mannose were detected as the whole-cell sugars. The major respiratory quinone was MK-9(H4) and ornithine was the diamino acid of the cell wall. The polar lipids present in strain Z28T were phosphatidylethanolamine, five phospholipids, two aminophospholipids, aminolipid and three unidentified lipids. Comparison of phenotypic and phylogenetic features between the two strains and the related organisms revealed that Z28T and Z29 represent a novel species of the genus Cellulomonas, for which the name Cellulomonas shaoxiangyii sp. nov. is proposed. The type strain is Z28T (=CGMCC 1.16477T=DSM 106200T).

Abstract
Two previously undescribed, Gram-stain-positive, rod-shaped strains, 410T and 553, were isolated from faeces of the Tibetan antelope (Pantholops hodgsonii) from the Tibet-Qinghai Plateau, PR China. The optimum growth conditions of the two novel strains were 1 % (w/v) NaCl, 37 °C and pH 7. The end products from glucose fermentation included ethanol and lactic acid. Based on results of 16S rRNA gene sequence comparison and phylogenetic and phylogenomic analyses, strains 410T and 553 were classified into the genus Actinomyces, and were closely related to Actinomyces ruminicola (97.6 %), Actinomyces oricola (93.5 %) and Actinomyces dentalis (90.8 %). The genomic G+C content of strain 410T was 67.4 mol%. Digital DNA-DNA hybridization values between strain 410T and each of the closely related species were under 70 %. The respiratory quinones were MK-10 (68 %) and MK-9 (32 %). The main cellular fatty acids of the isolates were C16 : 0, followed by C18 : 1 ω9c. The major polar lipids were diphosphatidylglycerol and phosphatidylinositol-mannoside. The whole-cell sugars contained rhamnose, ribose and glucose. The diagnostic amino acids of cell-wall peptidoglycan included alanine, glutamic acid, lysine and ornithine. The results of biochemical, chemotaxonomic and genotypic analyses revealed that the two novel strains represent a novel species of genus Actinomyces, for which the name Actinomyces qiguomingii sp. nov. is proposed. The type strain is 410T (=CGMCC 1.16361T= DSM 106201T).

Abstract
Cellulomonas spp. are often believed to be of low virulence. There are only a few reports of human infections. We report the first case of endocarditis caused by Cellulomonas in an intravenous drug abuser. The diagnosis of infective endocarditis (IE) in this case was definite using the Duke criteria. The course of the disease was complicated with a heart failure and possible mycotic aneurysm in the left leg. After the end of antimicrobial therapy aortic valve replacement was done because of severe heart failure.

Abstract
Two novel bacterial strains, designated Kc1T and Kc5T, were isolated from soil in Japan. Cells of the novel strains were Gram-reaction-positive, aerobic or facultatively anaerobic, motile rods. Phylogenetic analyses based on 16S rRNA gene sequences indicated that both strains belonged to the genus
Cellulomonas
. The 16S rRNA gene sequences of strains Kc1T and Kc5T showed closest similarity to that of
Cellulomonas terrae
DB5T (98.1 % and 98.4 % similarity, respectively), and the 16S rRNA gene similarity between the two novel strains was 97.8 %. In both strains, the major menaquinone was MK-9(H4), the predominant polar lipids were diphosphatidylglycerol and phosphatidylinositol mannosides, and the peptidoglycan contained ornithine and glutamic acid. Cell-wall sugars were identified as rhamnose, galactose and mannose in strain Kc1T and rhamnose and glucose in strain Kc5T. The DNA G+C contents of strains Kc1T and Kc5T were 73.6 mol% and 75.8 mol%, respectively. Based on the chemotaxonomic and physiological data and the results of DNA–DNA hybridizations, the two strains represent two novel species within the genus
Cellulomonas
, for which the names Cellulomonas soli sp. nov. (type strain Kc1T = DSM 24484T = JCM 17535T) and Cellulomonas oligotrophica sp. nov. (type strain Kc5T = DSM 24482T = JCM 17534T) are proposed.

Abstract
A Gram-positive, aerobic, motile, rod-shaped bacterium, designated strain T26T, was isolated from subsurface soil of Tianjin coal mine, China. Colonies were yellow–white, convex, circular, smooth and non-transparent on R2A agar. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain T26T was closely related to members of the genus
Cellulomonas
and a member of the genus

with 96.8–94.7 % and 96.7 % gene sequence similarities, respectively. The peptidoglycan type of strain T26T was A4β, containing l-ornithine–d-glutamic acid as the interpeptide bridge. The cell-wall sugars were rhamnose, galactose, xylose and inositol. The major fatty acids (>10 %) were anteiso-C15 : 0 (33.6 %), anteiso-C15 : 1 A (22.1 %), C16 : 0 (14.4 %) and C14 : 0 (12.1 %). The predominant respiratory quinone was MK-9(H4) and the genomic DNA G+C content was 74.4 mol%. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol-mannosides and phosphatidylinositol. Comparison of phenotypic and phylogenetic characteristics between strain T26T and related organisms revealed that the new isolate represented a novel species of the genus
Cellulomonas
, for which the name Cellulomonas carbonis sp. nov. is proposed. The type strain is T26T ( = CGMCC 1.10786T = KCTC 19824T = CCTCC AB2010450T).

Abstract
An alkalitolerant and moderately halophilic strain, designated KB23T, characterized by optimal growth at pH 8.0–9.0 and in the presence of 5–7 % (w/v) NaCl, was isolated from a reed (Phragmites australis) periphyton sample originating from an extremely shallow, alkaline soda pond located in Hungary. Cells of strain KB23T were Gram-stain-positive, motile straight rods. Strain KB23T was facultatively anaerobic, catalase-positive, oxidase-negative and contained peptidoglycan type A4β (l-Orn–d-Asp). MK-9(H4) was the predominant isoprenoid quinone and anteiso-C15 : 0, C16 : 0 and anteiso-C15 : 1 were the major cellular fatty acids. The DNA G+C content of strain KB23T was 74.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that this strain belongs to the genus Cellulomonas and that it is related most closely to Cellulomonas
flavigena DSM 20109T (97.35 % similarity), Cellulomonas
terrae DB5T (96.81 %), Cellulomonas
iranensis OT (96.75), Cellulomonas
chitinilytica X.bu-bT (96.60 %), Cellulomonas
persica IT (96.53 %), Cellulomonas
composti TR7-06T (96.45 %), Cellulomonas
biazotea DSM 20112T (96.34 %) and Cellulomonas
fimi DSM 20113T (96.20 %). According to these results, together with DNA–DNA hybridization and physiological data, strain KB23T is considered to represent a novel species of the genus Cellulomonas, for which the name Cellulomonas phragmiteti sp. nov. is proposed. The type strain is KB23T ( = DSM 22512T = NCAIM B002303T).

Abstract
Epizootic rabbit enteropathy (ERE) emerged and spread in Europe within the last 13 years causing major economical loss. The aims of the study was to evaluate antibiograms of TEC4, an inoculum composed of an extract of intestinal content of affected rabbits, and to test the potential of different antibiotic-based TEC4 fractions to reproduce the disease. Twenty nine different antibiotic discs were incubated for determining bacteria resistance. In a complementary study, nine tubes of liquid medium were inoculated with TEC4, incubated and added individually with amoxicillin/clavulanic acid, bacitracin, ceftiofur, doxycycline, novobiocin, streptomycyin, tylosin, vancomycin and 0.9% saline solution as control. The content of each tube was washed by centrifugation and suspended in saline. The three most effective antibiotics are florfenicol, amoxycillin/clavulanic acid and tylosin. A high concentration of Clostridium sordelli and Bacillus firmus were isolated in all fractions. Species never cultured from TEC4 were identified as Fusobacterium necrogenes (in vancomycin fraction), Cellulomonas sp (in novobiocin fraction) and Bacteroides distasonis (in doxycycline fraction). The ERE was reproduced when bacitracin, doxycycline and 0.9% fractions were inoculated. Rabbits showed ERE clinical signs with the specific drop in daily weight gain.
