A coccoid- to ovoid-shaped, Gram-positive, non-motile bacterial strain, designated phenol-AT, was isolated from an oil-contaminated coastal sand sample collected from Pingtung County, southern Taiwan, and characterized by use of a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that the novel strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus Brachybacterium in the family Dermabacteraceae, class Actinobacteria. The closest neighbours were Brachybacterium rhamnosum LMG 19848T (96.9 % 16S rRNA gene sequence similarity), Brachybacterium nesterenkovii DSM 9573T (97.0 %) and Brachybacterium muris C3H-21T (96.3 %). The peptidoglycan type of strain phenol-AT was variation A4γ with meso-diaminopimelic acid as the diagnostic cell-wall diamino acid. The isolate contained MK-7 as the major component of the quinone system. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, and unidentified phospholipids and glycolipids. The predominant fatty acid was anteiso-C15 : 0 (59.5 %); significant amounts of iso-C16 : 0 (9.4 %), iso-C14 : 0 (9.5 %) and anteiso-C17 : 0 (10.8 %) were also present. The isolate was also distinguished from recognized members of the genus Brachybacterium on the basis of several phenotypic and biochemical characteristics. It is evident from the genotypic, chemotaxonomic and phenotypic data that isolate phenol-AT represents a novel species of the genus Brachybacterium, for which the name Brachybacterium phenoliresistens sp. nov. is proposed. The type strain is phenol-AT (=LMG 23707T=BCRC 17589T).

A Gram-positive, non-motile, rod-shaped actinomycete strain, designated SSW1-57T, was isolated from a dried seaweed sample from the coast of Jeju Island, Republic of Korea and subjected to a polyphasic taxonomic study. A neighbour-joining tree based on 16S rRNA gene sequences showed that the organism was related to members of the family Nocardioidaceae and formed a separate branch at the base of a taxon encompassing members of the genus Aeromicrobium, whereas it occupied an intermediate position between Aeromicrobium alkaliterrae–Aeromicrobium marinum and Aeromicrobium erythreum–Aeromicrobium fastidiosum clusters in maximum-parsimony and maximum-likelihood trees. The phylogenetic association of the isolate with the genus Aeromicrobium was supported by the following chemotaxonomic properties: ll-diaminopimelic acid in the peptidoglycan, MK-9(H4) as the major menaquinone and major fatty acids cis-9-octadecenoic acid, hexadecanoic acid, 10-methyl octadecanoic acid and 2-hydroxy hexadecanoic acid. The polar lipid profile contained phosphatidylinositol, diphosphatidylglycerol and phosphatidylglycerol. Levels of 16S rRNA gene sequence similarity between the novel organism and the type strains of the four recognized Aeromicrobium species were in the range 96.5–96.7 %. On the basis of phylogenetic analyses and phenotypic data, it is proposed that the organism should be classified as representing a novel species of the genus Aeromicrobium, with the name Aeromicrobium tamlense sp. nov. The type strain is SSW1-57T (=JCM 13811T=NRRL B-24466T).

A bacterial strain designated LTC-2T was isolated from a freshwater lake in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain LTC-2T were Gram-reaction-negative, facultatively anaerobic, poly-β-hydroxybutyrate-accumulating, motile by means of a monopolar flagellum, non-spore-forming, slightly curved rods surrounded by a thick capsule and formed creamy white colonies. Growth occurred at 10–37 °C (optimum, 20–30 °C), at pH 6.0–9.0 (optimum, pH 7.0–8.0) and with 0–1.0 % NaCl (optimum, 0 %). The predominant fatty acids were C18 : 1ω7c, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The major isoprenoid quinone was Q-10 and the DNA G+C content was 58.5 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, two uncharacterized phospholipids and two uncharacterized aminophospholipids. The major polyamines were putrescine, homospermidine and spermidine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain LTC-2T forms a distinct lineage with respect to closely related genera in the family Rhodospirillaceae , most closely related to the genera Elstera and Dongia , and the levels of 16S rRNA gene sequence similarity with respect to the type species of related genera were less than 94 %. On the basis of the genotypic and phenotypic data, strain LTC-2T represents a novel genus and species of the family Rhodospirillaceae , for which the name Lacibacterium aquatile gen. nov., sp. nov. is proposed. The type strain is LTC-2T ( = BCRC 80445T = LMG 26999T = KCTC 32017T).

A novel Gram-stain-positive, aerobic, motile, non-spore-forming coccus-shaped actinomycete, designated strain YIM 121300T, was isolated from alkaline sediment in Yuanjiang, Yunnan province, south-west China. Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain YIM 121300T was affiliated to the genus Kineococcus, and was closely related to Kineococcus aurantiacus IFO 15268T (97.3 % similarity). 16S rRNA gene sequence similarity to other species of the genus Kineococcus was < 97 %. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The whole-cell sugars contained arabinose, galactose, glucose, mannose and ribose. The predominant menaquinone was MK-9(H2). Mycolic acids were not detected. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown phospholipid. The predominant fatty acids were anteiso-C15 : 0 and anteiso-C15 : 1 A. The G+C content of the genomic DNA was 75.1 mol%. DNA–DNA relatedness (55 ± 4 % to K. aurantiacus IFO 15268T) and differential phenotypic data demonstrated that strain YIM 121300T was distinguished from all related species of the genus Kineococcus. On the basis of data from the present polyphasic study, the organism should be assigned to a novel species of the genus Kineococcus, for which the name Kineococcus gypseus sp. nov. is proposed. The type strain is YIM 121300T ( = CCTCC AA 2013232T = DSM 27627T).

A Gram-positive, non-motile, spherical, non-spore-forming bacterial strain, DS-52T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. It grew optimally at 25 °C and pH 6.0–7.0. Strain DS-52T had meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, and galactose, mannose, xylose and rhamnose as whole-cell sugars. It contained MK-8(H4) and MK-9(H4) as the predominant menaquinones and anteiso-C15 : 0, iso-C15 : 0 and C17 : 0 as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyldimethylethanolamine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-52T is most closely related to the genus Nakamurella of the suborder Frankineae. Strain DS-52T exhibited 16S rRNA gene sequence similarity values of 96.5 % to Nakamurella multipartita JCM 9543T and 92.0–93.9 % to other members of the suborder Frankineae. The diagnostic diamino acid type and polar lipid profile of strain DS-52T were the same as those of the genus Nakamurella. However, strain DS-52T could be clearly distinguished from the genus Nakamurella by differences in predominant menaquinones, major fatty acids and cell-wall sugars. Accordingly, based on combined phenotypic, chemotaxonomic and phylogenetic data, strain DS-52T (=KCTC 19127T=CIP 108919T) is proposed as the type strain of a novel species in a new genus, Humicoccus flavidus gen. nov., sp. nov.

A facultatively anaerobic, chitinolytic bacterium, strain KL-9T, was isolated from a freshwater lake in Taiwan and characterized by using a polyphasic taxonomic approach. Cells of strain KL-9T were Gram-negative, rod-shaped, motile by means of a single polar flagellum and non-spore-forming. Growth occurred at 15–40 °C (optimum, 30–37 °C), at pH 7.0–9.0 (optimum, pH 8.0) and with 0–1.0 % NaCl (optimum, 0 %). The predominant fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The major isoprenoid quinone was Q-8. The DNA G+C content of strain KL-9T was 64.6 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidyldimethylethanolamine and several uncharacterized phospholipids and aminolipids. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain KL-9T formed a distinct lineage with respect to closely related genera within the class Betaproteobacteria , being most closely related to members of the genera Leeia , Chitinimonas , Silvimonas and Andreprevotia . Levels of 16S rRNA gene sequence similarity with respect to the type strains of type species of these genera were below 91 %. On the basis of genotypic and phenotypic data, strain KL-9T is thus considered to represent a novel species of a new genus within the class Betaproteobacteria , for which the name Chitinivorax tropicus gen. nov., sp. nov. is proposed. The type strain of Chitinivorax tropicus is KL-9T ( = BCRC 80168T = LMG 25530T).
