Cells of bacterial strains 4 G-K06T and 4MSK11T, isolated from soil samples collected from monsoon evergreen broad-leaved forest of the Dinghushan Mountain (112° 31′ E 23° 10′ N), Guangdong Province, PR China, were Gram-stain-negative, aerobic, non-spore-forming, non-motile and rod-shaped. Strain 4 G-K06T grew at 10–37 °C, pH 3.5–7.5 and 0–3.5 % (w/v) NaCl; while 4MSK11T grew at 4–42 °C, pH 3.5–7.5 and 0–2.5 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed strain 4 G-K06T formed a clade with Dyella flagellata 4 M-K16T, Dyella acidisoli 4M-Z03T, Dyella humi DHG40T and Dyella nitratireducens DHG59T, while strain 4MSK11T formed a clade with Dyella caseinilytica DHOB09T and Dyella mobilis DHON07T, both within the genus Dyella . The result of the partial atpD, gyrB and lepA gene sequence analysis supported the conclusion based on 16S rRNA gene sequence analysis, which showed that these two strains represent two novel species of Dyella . The average nucleotide identity and digital DNA–DNA hybridization value for the whole genomes were 75.0–79.0 and 20.3–22.6 % between strains 4 G-K06T, 4MSK11T and those described Dyella species with genome sequences; while the DNA–DNA hybridization rates between strains 4 G-K06T, 4MSK11T and closely related Dyella species (without genome sequence) were 29.5–41.8 %. The major cellular fatty acids of these two strains were iso-C15 : 0, iso-C16 : 0 and iso-C17 : 1 ω9c, while the major polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several unidentified phospholipids and aminophospholipids. The only ubiquinone of these two strains was ubiquinone-8. The DNA G+C contents of 4 G-K06T and 4MSK11T were 60.4 and 61.3 mol%, respectively. On the basis of the evidence presented here, strains 4 G-K06T and 4MSK11T represent two novel species of the genus Dyella , for which the names Dyella monticola sp. nov. (type strain 4 G-K06T=LMG 30268T=GDMCC 1.1188T) and Dyella psychrodurans sp. nov. (type strain 4MSK11T=KCTC 62280T=GDMCC 1.1185T) are proposed.

A Gram-stain-negative bacterium, designated strain Marseille-Q3039T, was isolated from subgingival dental plaque of a woman with gingivitis in Marseille, France. Strain Marseille-Q3039T was found to be an anaerobic, motile and spore-forming crescent-shaped bacterium that grew at 25–41.5 °C (optimum, 37 °C), pH 5.5–8.5 (optimum, pH 7.5) and salinity of 5.0 g l−1 NaCl. The results of 16S rRNA gene sequence analysis revealed that strain Marseille-Q3039T was closely related to Selenomonas infelix ATCC 43532T (98.42 % similarity), Selenomonas dianae ATCC 43527T (97.25 %) and Centipedia periodontii DSM 2778T (97.19 %). The orthologous average nucleotide identity and digital DNA–DNA hybridization relatedness between strain Q3039T and its closest phylogenetic neighbours were respectively 84.57 and 28.2 % for S. infelix ATCC 43532T and 83.93 and 27.2 % for C. periodontii DSM 2778T. The major fatty acids were identified as C13 : 0 (27.7 %), C15 : 0 (24.4 %) and specific C13 : 0 3-OH (12.3 %). Genome sequencing revealed a genome size of 2 351 779 bp and a G+C content of 57.2 mol%. On the basis of the results from phenotypic, chemotaxonomic, genomic and phylogenetic analyses and data, we concluded that strain Marseille-Q3039T represents a novel species of the genus Selenomonas , for which the name Selenomonas timonae sp. nov. is proposed (=CSUR Q3039=CECT 30128).

‘Bacillus macroides’ ATCC 12905T ( = DSM 54T = LMG 18474T), isolated in 1947 from cow dung, was not included in the Approved Lists of Bacterial Names and so it lost standing in bacteriological nomenclature. Reinvestigation of the strain, including DNA–DNA relatedness experiments, revealed that ‘Bacillus macroides’ is genomically distinct from its closest relatives Lysinibacillus xylanilyticus , Lysinibacillus boronitolerans and Lysinibacillus fusiformis (as determined by 16S rRNA gene sequence analysis, with pairwise similarity values of 99.2, 98.8 and 98.5 %, respectively, with the type strains of these species). Further analysis showed that ‘Bacillus macroides’ shares the A4α l-Lys–d-Asp peptidoglycan type with other members of the genus Lysinibacillus and can thus be attributed to this genus. These results, combined with additional phenotypic data, justify the description of strain LMG 18474T ( = DSM 54T = ATCC 12905T) as Lysinibacillus macroides sp. nov., nom. rev.

The taxonomic position of a novel aerobic, Gram-positive actinobacteria, designated strain RB5T, was determined using a polyphasic approach. The strain, isolated from the gut of the fungus-farming termite Macrotermes natalensis, showed morphological, physiological and chemotaxonomic properties typical of the genus Streptomyces . Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbour of RB5T was Streptomyces polyrhachis DSM 42102T (98.87 %). DNA–DNA hybridization experiments between strain RB5T and S. polyrhachis DSM 42102T resulted in a value of 27.4 % (26.8 %). The cell wall of strain RB5T contained ll-diaminopimelic acid as the diagnostic amino acid. Mycolic acids and diagnostic sugars in whole-cell hydrolysates were not detected. The strain produced the following major phospholipids: diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannoside and phosphatidylserine. The menaquinone profile showed hexa- and octahydrogenated menaquinones containing nine isoprene units [MK-9(H6) and MK-9(H8)]. The strain exhibited a fatty acid profile containing the following major fatty acids: 12-methyltridecanoic acid (iso-C14 : 0) 12-methyltetradecanoic acid (anteiso-C15 : 0), 13-methyltetradecanoic acid (iso-C15 : 0) and 14-methylpentadecanoic acid (iso-C16 : 0). Here, we propose a novel species of the genus Streptomyces – Streptomyces smaragdinus with the type strain RB5T (=VKM Ac-2839T=NRRL B65539T).
