A yellow-coloured bacterial strain, designated HB2T, isolated from stratum water was investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was a member of the genus Luteimonas , its three closest neighbours being Luteimonas aquatica BCRC 17731T (97.5 % similarity), Luteimonas marina JCM 12488T (97.3 %) and Luteimonas aestuarii DSM 19680T (96.9 %). Strain HB2T could clearly be distinguished from these type strains based on phylogenetic analysis, DNA–DNA hybridization, fatty acid composition and a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strain HB2T represents a novel species of the genus Luteimonas , for which the name Luteimonas huabeiensis sp. nov. is proposed. The type strain is HB2T ( = DSM 26429T = CICC 11005sT).

A Gram-stain-negative bacterium, designated SP-35T, was isolated from compost and was subjected to a taxonomic study. This isolate was short-rod-shaped and non-spore-forming. Phylogenetic analysis based on 16S rRNA sequence comparison indicated the isolate was related to the genus Comamonas . 16S rRNA gene sequence analysis showed that its closest neighbours were the type strains Comamonas odontotermitis Dant 3-8T (96.8 % similarity), Comamonas testosteroni DSM 50244T (96.5 %), Comamonas guangdongensis CY01T (95.9 %) and Comamonas composti YY287T (95.6 %). Using phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data and a range of physiological and biochemical characteristics we could clearly distinguish strain SP-35T from type strains of the genus Comamonas . The genomic DNA G+C content of strain SP-35T was 63.1 mol%. The predominant cellular fatty acids were C16 : 0, C17 : 0 cyclo, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidlyglycerol. Differences in phenotypic and phylogenetic characteristics support the classification of strain SP-35T as a representative of a novel species in the genus Comamonas , for which the name Comamonas serinivorans sp. nov. is proposed. The type strain is SP-35T ( = DSM 26136T = JCM 18194T).

A novel endophytic actinomycete, designated strain NEAU-LZS-5T, was isolated from the leaf of candelabra aloe (Aloe arborescens Mill) and characterized using a polyphasic approach. Analysis of the 16S rRNA gene sequence showed that strain NEAU-LZS-5T belongs to the genus Streptomyces and exhibited 99.51 and 97.37 % similarity to Streptomyces sedi YIM 65188T and Streptomyces specialis GW41-1564T, respectively, whereas low similarity values (<97 %) distinguished strain NEAU-LZS-5T from all other species of the genus Streptomyces with validly published names. Two tree-making algorithms also supported the position that strain NEAU-LZS-5T formed a distinct clade with Streptomyces sedi YIM 65188T and Streptomyces specialis GW41-1564T. However, levels of DNA–DNA relatedness between strain NEAU-LZS-5T and Streptomyces sedi YIM 65188T and Streptomyces specialis GW41-1564T were 45.59 and 31.90 %, respectively. A comparative study between strain NEAU-LZS-5T and the type strains of closest related species of the genus Streptomyces revealed that it differed from them in morphological, physiological and biochemical characteristics. Therefore, strain NEAU-LZS-5T represents a novel species of the genus Streptomyces , for which the name Streptomyces zhaozhouensis sp. nov. is proposed. The type strain is NEAU-LZS-5T ( = CGMCC 4.7095T = DSM 42101T).

A novel actinobacterium, designated strain BR-34T, was isolated from rhizosphere soil of bamboo (Phyllostachys nigro var. henonis) sampled in Damyang, Korea. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Catenulispora . The strain contained iso-C16 : 0 as the major fatty acid and MK-9(H4), MK-9(H6) and MK-9(H8) as major isoprenoid quinones. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BR-34T formed a cluster separate from members of the genus Catenulispora and was related most closely to Catenulispora acidiphila ID139908T (97.4 % similarity), Catenulispora rubra Aac-30T (97.3 %), Catenulispora yoronensis TT N02-20T (97.3 %) and Catenulispora subtropica TT 99-48T (97 %). However, the level of DNA–DNA relatedness between strain BR-34T and C. acidiphila ID139908T was only 45.32 %. Based on DNA–DNA relatedness, morphological and phenotypic data, strain BR-34T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Catenulispora , for which the name Catenulispora graminis sp. nov. is proposed. The type strain is BR-34T ( = KACC 15070T = NBRC 107755T).

A novel actinobacterium, strain A8036T, isolated from soil, was investigated by using a polyphasic taxonomic approach. The organism formed extensively branched substrate hyphae that generated spiral chains of spores with irregular surfaces. The cell wall contained meso-diaminopimelic acid (type III) and cell-wall sugars were glucose, madurose, mannose and ribose. The predominant menaquinones were MK-9(H6) and MK-9(H4). The phospholipids were diphosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major cellular fatty acids were iso-C16 : 0, C17 : 1 cis9, C16 : 0, C15 : 0 and 10-methyl C17 : 0. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of strain A8036T were Actinomadura meyerae DSM 44715T (99.23 % similarity), Actinomadura bangladeshensis DSM 45347T (98.9 %) and Actinomadura chokoriensis DSM 45346T (98.3 %). However, DNA–DNA relatedness and phenotypic data demonstrated that strain A8036T could be clearly distinguished from the type strains of all closely related Actinomadura species. Strain A8036T is therefore considered to represent a novel species of the genus Actinomadura , for which the name Actinomadura geliboluensis sp. nov. is proposed. The type strain is A8036T ( = DSM 45508T = KCTC 19868T).

Strain VN07A0015T was isolated from soil collected on Cat Ba Island, Vietnam. The taxonomic position of strain VN07A0015T was near Streptomyces aomiensis M24DS4T (98.5 % 16S rRNA gene sequence similarity) and Streptomyces scabrisporus NBRC 100760T (95.6 %), and it clustered within them; however, this cluster was distant from the type strains of other species of the genus Streptomyces . The aerial mycelia of strain VN07A0015T were greyish and formed imperfect spiral spore chains (retinaculiaperti type) with smooth-surfaced spores. The morphological features of strain VN07A0015T were different from those of the type strains of S. aomiensis and S. scabrisporus . The chemotaxonomic characteristics of strain VN07A0015T were typical for all members of the genus Streptomyces , which possessed ll-type diaminopimelic acid, menaquinone MK-9(H6, H8) and the major fatty acids iso-C16 : 0 and iso-C15 : 0. DNA–DNA relatedness between strain VN07A0015T and S. aomiensis NBRC 106164T was less than 30 %. In addition, some physiological and biochemical traits differed from those of S. aomiensis . Therefore, we propose that strain VN07A0015T be classified in the genus Streptomyces as a representative of Streptomyces catbensis sp. nov. (type strain VN07A0015T = VTCC-A-1889T = NBRC 107860T).

Genomic Relatedness

Two species of the genus Deinococcus , namely Deinococcus wulumuqiensis Wang et al. 2010 and Deinococcus xibeiensis Wang et al. 2010, were simultaneously proposed and described in the same publication. However, the identical 16S rRNA gene sequence of the two type strains strongly raised the probability of their relatedness at the species level. Thus, the genomic relatedness of the two species of the genus Deinococcus was investigated here to clarify their taxonomic status. The high (99.9 %) average nucleotide identity (ANI) between the genome sequences of the two type strains suggested that the two species are synonymous. Additional phenotypic data including enzymic activities and substrate-utilization profiles showed no pronounced differences between the type strains of the two species. Data from this study demonstrated that the two taxa constitute a single species. According to Rule 42 of the Bacteriological Code, we propose that D. xibeiensis Wang et al. 2010 should be reclassified as a subjective heterotypic synonym of D. wulumuqiensis Wang et al. 2010.

The taxonomic status of a bacterium, strain DC-8T, isolated from activated sludge, was determined using a polyphasic taxonomic approach. The cells of strain DC-8T were Gram-negative, non-motile, non-spore-forming and rod-shaped. The isolate grew at temperature range of 10–40 °C (optimum 30–35 °C), pH range of 5.0–10.0 (optimum 6.5–8.0) and NaCl concentrations of 0–5 % (optimum 0–1 %). The predominant menaquinone of strain DC-8T was MK-7 and major fatty acids were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c; 39.7 %), iso-C15 : 0 (33.7 %) and C16 : 0 (5.2 %). The DNA G+C content was 39.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain DC-8T was a member of the genus Sphingobacterium . Strain DC-8T shared the highest similarity with Sphingobacterium siyangense SY1T (98.4 %), Sphingobacterium multivorum IAM 14316T (98.3 %), Sphingobacterium canadense CR11T (98.0 %) and Sphingobacterium detergens 6.2ST (97.9 %) and shared less than 97 % similarity with other members of the genus Sphingobacterium . DNA–DNA hybridization experiments showed that the DNA–DNA relatedness values between strain DC-8T and its closest phylogenetic neighbours were below 70 %. Based on the phylogenetic analysis, DNA–DNA hybridization, whole-cell fatty acid composition as well as biochemical characteristics, strain DC-8T was clearly distinguished from all recognized species of the genus Sphingobacterium and should be classified as a representative of a novel species of the genus Sphingobacterium , for which the name Sphingobacterium caeni sp. nov. is proposed. The type strain is DC-8T ( = CCTCC AB 2012020T = KACC 16850T).

A bacterial strain, designated NSW-5T, was isolated from a water sample taken from Niao-Song Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain NSW-5T were strictly aerobic, Gram-stain-negative, non-motile and polymorphic, being straight, vibrioid, curved and spiral-shaped rods surrounded by a thick capsule and forming light pink-coloured colonies. Some rings consisting of several cells were present. Growth occurred at 10–40 °C (optimum, 25 °C), with 0–3.0 % NaCl (optimum, 0 %) and at pH 6.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NSW-5T belonged to the genus Arcicella with sequence similarities of 98.6, 98.0 and 97.3 % with Arcicella aquatica NO-502T, Arcicella rosea TW5T and Arcicella aurantiaca TNR-18T, respectively. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 20.8 %), C16 : 0 (14.6 %), iso-C15 : 0 (13.8 %), C16 : 1ω5c (12.5 %) and C18 : 0 (11.4 %), and the only respiratory quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized glycolipids, aminolipids, phospholipids and aminophospholipids. The DNA G+C content of strain NSW-5T was 44.1 mol%. The DNA–DNA relatedness of strain NSW-5T with respect to recognized species of the genus Arcicella was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain NSW-5T should be classified as a representative of a novel species, for which the name Arcicella rigui sp. nov. is proposed. The type strain is NSW-5T ( = KCTC 23307T = BCRC 80260T). Emended descriptions of the genus Arcicella and of Arcicella aquatica , Arcicella rosea and Arcicella aurantiaca are also proposed.

‘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.

A newly isolated facultatively methylotrophic bacterium (strain 3tT) was investigated. Cells of the isolate were Gram-stain-negative, asporogenous, non-motile rods that multiplied by binary fission. The strain utilized methanol, methylamine and a variety of multicarbon compounds as carbon and energy sources. Growth occurred at pH 6.5–8.5 (optimally at 7.0–7.5) and at 10–45 °C (optimally at 30–37 °C). The major fatty acids of methanol-grown cells were C16 : 1ω7c and C16 : 0. The predominant phospholipids were phosphatidylethanolamine and phosphatidylglycerol. The major ubiquinone was Q-8. Strain 3tT possessed pyrroloquinoline quinone (PQQ)-linked methanol dehydrogenase and assimilated C1 units at the level of formaldehyde and CO2 via the serine cycle. The DNA G+C content of the strain was 63.6 mol% (T m). On the basis of 16S rRNA gene sequence similarity (98.1 %) and rather low DNA–DNA relatedness (30 %) with the type strain of the type species of the genus Methyloversatilis ( Methyloversatilis universalis FAM5T), and physiological and biochemical characteristics, the isolate was classified as a representative of a new species of the genus and named Methyloversatilis thermotolerans 3tT ( = VKM B-2692T = CCUG 61694T = DSM 25156T).
