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).

A Gram-positive, non-spore-forming bacterium (GW-12028T) of unknown origin showing filamentous growth and producing spherical sporangia was studied for its taxonomic allocation. The 16S rRNA gene sequence analysis and subsequent similarity studies showed that strain GW-12028T belongs to the genus Streptosporangium , and is most closely related to Streptosporangium pseudovulgare DSM 43181T (99.9 %) and Streptosporangium nondiastaticum DSM 43848T (99.6 %) and more distantly related to Streptosporangium fragile IFO 14311T (98.4 %) and other species of the genus Streptosporangium (95.8 to 98 %). Chemotaxonomic analyses showed that the peptidoglycan diamino acid was meso-diaminopimelic acid. Whole-cell hydrolysates contained madurose as the diagnostic sugar and exhibited a quinone system that contained predominantly menaquinones with nine isoprenoic units in the side chain [MK-9, MK-9(H2), MK-9(H4)]. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phoshatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannosides, four unidentified glycolipids, a phospholipid and an aminolipid. The polyamine pattern contained the major compounds spermine and spermidine. The major fatty acids were 10-methyl C17 : 0, iso-C16 : 0 and C15 : 0. These chemotaxonomic traits are common to other species of the genus Streptosporangium . DNA–DNA hybridizations and physiological and biochemical tests in comparison with the type strains of the most closely related species, S. nondiastaticum and S. pseudovulgare , allowed genotypic and phenotypic differentiation of strain GW-12028T. This strain represents a novel species, for which we propose the name Streptosporangium sandarakinum sp. nov., with the type strain GW-12028T ( = LMG 27062T  = DSM 45763T).

Strain F2AT, isolated from the cricket Acheta domesticus, was subjected to a polyphasic taxonomic characterization. Cells of the strain were rod-shaped, Gram-stain-negative and catalase- and oxidase-positive. It did not assimilate any carbohydrates. The strain's 16S rRNA gene sequence showed highest similarity to Entomomonas moraniae QZS01T (96.4 %). The next highest similarity values were found to representatives of related genera (<93 %). The genome size of strain F2AT was 3.2 Mbp and the G+C content was 36.4 mol%. Average nucleotide identity values based on blast and MUMmer and average amino acid identity values between strain F2AT and E. moraniae QZS01T were 74.29/74.43, 83.88 and 74.70 %, respectively. The quinone system predominantly contained ubiquinone Q-8. In the polar lipid profile, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified phospholipid were detected. The polyamine pattern consisted of the major compounds putrescine and spermidine. Major fatty acids were C18 : 1 ω7c and C16 : 0 and the hydroxyl acids were C12 : 0 3-OH, C14 : 0 2-OH and C14 : 0 3-OH. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. Due to its association with the only species of the genus Entomomonas but its distinctness from E. moraniae we here propose the novel species Entomomonas asaccharolytica sp. nov. F2AT (=CCM 9136T=LMG 32211T).

A Gram-stain-positive, rod-shaped, motile bacterial strain, designated 3-2-2T, was isolated from field topsoil collected from a western suburb of Nanyang city, Henan province, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 3-2-2T was a member of the genus Bacillus and most closely related to Bacillus fortis R-6514T (98.9 % similarity), Bacillus terrae RA9T (98.0 %) and Bacillus fordii R-7190T (97.7 %). A draft genome sequence determined for strain 3-2-2T revealed a DNA G+C content of 42.2 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between 3-2-2T and the closely related Bacillus species ranged 79.4–84.2 % and 23.4–24.6 %. The major fatty acids of strain 3-2-2T were iso-C15 : 0, anteiso-C15 : 0, iso-C14 : 0 and iso-C16 : 0. The major isoprenoid quinone was MK-7. meso-Diaminopimelic acid was detected in the peptidoglycan. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid and an unidentified lipid. The results of phylogenetic analyses, in silico genomic comparisons, and chemotaxonomic and phenotypic analyses clearly indicated that strain 3-2-2T represents a novel species within the genus Bacillus , for which the name Bacillus acidinfaciens sp. nov. is proposed. The type strain is 3-2-2T (=CGMCC 1.13685T=LMG 30839T).

Three Gram-stain-negative, non-motile, oxidase- and catalase-positive, rod-shaped, black, facultative phototrophic bacterial strains, RG-N-1aT, DMA-N-7a and RA-N-9 were isolated from the water sample from Lake Fertő/Neusiedler See (Hungary). Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the strains form a distinct linage within the family Rhodobacteraceae and their closest relatives are Tabrizicola piscis K13M18T (96.32%) followed by Cypionkella psychrotolerans PAMC 27389T (96.25%). The novel bacterial strains prefer alkaline environments and grow optimally at 23–33 °C in the presence of NaCl (1–2 w/v%). Bacteriochlorophyll a was detected. Cells contained exclusively ubiquinone Q-10. The major cellular fatty acids were C18 : 1ω7c, C19 : 1iso ω5c, C18 : 0 3-OH and C18 : 1ω7c 11-methyl. The polar lipid profile contains diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified phospholipid and four unidentified lipids. The assembled draft genome of RG-N-1aT had 33 contigs with N50 values 315 027 nt, 96× genome coverage, total length of 4 326 551 bp and a DNA G+C content of 64.9%. Genome-based calculations (genome-to-genome distance and DNA G+C percentage) and pairwise amino acid identity (AAI <73.5%) indicate that RG-N-1aT represents a novel genus. RG-N-1aT (=DSM 108317T=NCAIM B.02647T) is suggested as the type strain of a novel genus and species in the family Rhodobacteraceae , for which the name Fertoeibacter niger gen. nov., sp. nov. is proposed.
