Two novel Gram-staining-positive, rod-shaped, endospore-forming and moderately thermophilic bacteria, designated strains DX-3T and GIESS002, were isolated from sludge composts from Guangdong Province, China. Analysis of 16S rRNA gene sequences revealed that the isolates were closely related to each other with extremely high similarity (99.6 %), and were members of the family Bacillaceae . However, these two isolates formed a novel phylogenetic branch within this family. Their closest relatives were the members of the genera Ornithinibacillus , Oceanobacillus and Virgibacillus . Cells of both strains were facultatively anaerobic and catalase- and oxidase-positive. The cell-wall peptidoglycan type was A1γ (meso-diaminopimelic acid direct). The predominant isoprenoid quinone was MK-7. The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major cellular fatty acid was iso-C15 : 0. The DNA G+C content was 43.2–43.7 mol%. The results of a polyphasic taxonomic study indicated that strains DX-3T and GIESS002 represent a novel species in a new genus in the family Bacillaceae , order Bacillales , for which the name Compostibacillus humi gen. nov., sp. nov. is proposed. The type strain is DX-3T ( = KCTC 33104T = CGMCC 1.12360T).

A Gram-staining-positive, aerobic, non-motile, irregular coccus, designated strain YIM M13146T, was isolated from a sediment sample collected from the South China Sea at a depth of 2439 m, and its taxonomic position was determined by a polyphasic approach. Optimal growth of the strain was observed at 30 °C (range 5–40 °C), pH 7.0 (pH 6.0–9.0) and 0–1 % NaCl (0–6 %, w/v) on/in tryptic soy agar/broth. Strain YIM M13146T had the major cellular fatty acid anteiso-C15 : 0, the predominant respiratory menaquinone MK-9(H4), peptidoglycan type A3γ (ll-DAP–Gly) containing alanine, glycine, glutamic acid and ll-diaminopimelic acid (ll-DAP) and the polar lipids phosphatidylcholine, diphosphatidylglycerol, one unknown phospholipid and several glycolipids. The G+C content of the DNA was 67.2 mol%. Phenotypic and chemotaxonomic characteristics together with 16S rRNA gene sequence analyses showed that strain YIM M13146T was distinct from its close phylogenetic relatives in the genera Propioniferax and Granulicoccus of the family Propionibacteriaceae . Hence, a new genus and species, Mariniluteicoccus flavus gen. nov., sp. nov., is proposed. The type strain of Mariniluteicoccus flavus is YIM M13146T ( = DSM 25892T = CCTCC AB 2012055T).

Eight facultatively anaerobic rod-shaped bacteria were isolated from raw milk and two other dairy products. Results of phylogenetic analyses based on 16S rRNA gene sequences showed that the isolates are placed in a distinct lineage within the family Propionibacteriaceae with Propioniciclava sinopodophylli and Propioniciclava tarda as the closest relatives (94.6 and 93.5 % similarity, respectively). The cell-wall peptidoglycan contained meso-diaminopimelic acid, alanine and glutamic acid and was of the A1γ type (meso-DAP-direct). The major cellular fatty acid was anteiso-C15 : 0 and the major polar lipids were diphosphatidylglycerol, phosphatidyglycerol and three unidentified glycolipids. The quinone system contained predominantly menaquinone MK-9(H4). The G+C content of the genomic DNA of strain VG341T was 67.7 mol%. The whole-cell sugar pattern contained ribose, rhamnose, arabinose and galactose. On the basis of phenotypic and genetic data, eight strains (VG341T, WS4684, WS4769, WS 4882, WS4883, WS4901, WS4902 and WS4904) are proposed to be classified as members of a novel species in a new genus of the family Propionibacteriaceae , for which the name Brevilactibacter flavus gen. nov., sp. nov. is proposed. The type strain is VG341T (=WS4900T=DSM 100885T=LMG 29089T) and seven additional strains are WS4684, WS4769, WS4882, WS4883, WS4901, WS4902 and WS4904. Furthermore, we propose the reclassification of P. sinopodophylli as Brevilactibacter sinopodophylli comb. nov.

Genomic Characterization

A Gram-stain-negative, oxidase-positive, catalase-positive, aerobic, orange-pigmented, rod-shaped and non-motile bacterium designated strain MMS17-SY002T was isolated from island soil. The isolate grew at 20–37 °C (optimum, 30 °C), at pH 6.0–9.5 (optimum, pH 7) and in the presence of 0.5–4.0 % (w/v) NaCl (optimum, 2.0 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MMS17-SY002T was mostly related to the genus Muriicola of the family Flavobacteriaceae and had highest sequence similarity of 96.82 % to Muriicola marianensis A6B8T and Muriicola jejuensis EM44T, but formed a distinct phylogenetic line within the genus. Chemotaxonomic analyses showed that menaquinone 6 was the predominant isoprenoid quinone, the major fatty acids were iso-C15 : 1 G and iso-C15 : 0, and the diagnostic polar lipid was phosphatidylethanolamine. The genomic DNA G+C content was 42.4 mol%. Strain MMS17-SY002T could be distinguished from related species by the combination of trypsin, α-chymotrypsin, acid phosphatase, naphthol-AS-BI-phosphohydrolase, α-galactosidase, β-galactosidase and β-glucosidase activities. The orthologous average nucleotide identity between the genomes of strain MMS17-SY002T and M. jejuensis and that between the strain and M. marianensis A6B8T were 73.26 and 73.33%, respectively, thus confirming the separation of the strain from related species at species level. Based on the phenotypic, phylogenetic, chemotaxonomic and genomic characterization, MMS17-SY002T should be recognized as a novel species of the genus Muriicola , for which the name Muriicola soli sp. nov. is proposed. The type strain is MMS17-SY002T (=KCTC 62790T=JCM 32370T).
