Two novel, Gram-stain-variable, moderately thermophilic, acidophilic, rod-shaped, endospore-forming bacteria, G45-16T and G45-17, were isolated from acid mine water of Zijin copper mine in Fujian Province, China. Phylogenetic analysis of 16S rRNA gene sequences showed that they were closely related to Alicyclobacillus acidoterrestris ATCC 49025T with sequence similarities of 96.8 %. Cells grew aerobically at 20–45 °C (optimum, 40 °C), at pH 2.5–5.5 (optimum, pH 3.5) and in the presence of 0–4.0 % (w/v) NaCl. Strains contained MK-7 as the major menaquinone and the major cellular fatty acids were ω-cyclohexane C19 : 0 and ω-cyclohexane C17 : 0. The DNA G+C content was 51.3 and 49.8 mol% (T m) for G45-16T and G45-17, respectively. On the basis of phenotypic, chemotaxonomic and phylogenetic comparisons with their relatives and DNA–DNA relatedness values, it is concluded that strains G45-16T and G45-17 represent a novel species within the genus Alicyclobacillus, for which the name Alicyclobacillus fodiniaquatilis sp. nov. is proposed; the type strain is G45-16T ( = CGMCC 1.15049T = NBRC 111483T).

The polar lipids present included phosphatidylethanolamine, one unknown aminophospholipid, two unknown aminolipids and five unknown polar lipids. The DNA G+C content of this strain was 54 mol%. Based on phenotypic, genotypic and chemotaxonomic data, strain PR1012KT represents a novel species in the genus Spirosoma, for which the name Spirosoma aerolatum sp. nov. is proposed.

Strain 15-4T, a Gram-stain-negative, rod-shaped, non-motile bacterial strain that produced flexirubin-type pigments, was isolated from Tibet Province, China, and characterized by using a polyphasic taxonomic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the family Chitinophagaceae, phylum ‘Bacteroidetes’, and was related to members of the genus Niabella, with sequence similarities ranging from 94.1 to 96.4 %. Strain 15-4T contained MK-7 as the predominant menaquinone and its DNA G+C content was 46.9 mol%. The major fatty acids of strain 15-4T were iso-C15 : 0 (41.3 %), iso-C15 : 1 G (14.9 %), iso-C17 : 0 3-OH (13.2 %) and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH, 16.0 %). These chemotaxonomic data supported the affiliation of strain 15-4T to the genus Niabella. However, a number of physiological and biochemical features enabled the isolate to be differentiated phenotypically from recognized species of the genus Niabella. On the basis of the evidence presented, it is proposed that strain 15-4T represents a novel species, Niabella tibetensis sp. nov.; the type strain is 15-4T ( = CCTCC AB 209167T = NRRL B-59394T). On the basis of these data, an emended description of the genus Niabella is also proposed.

A Gram-negative, aerobic, rod-shaped, motile Brevundimonas-like bacterial strain, J22T, was isolated from black sand collected from Soesoggak, Jeju Island, Korea. Growth of strain J22T was observed in R2A medium at temperatures between 10 and 42 °C (optimum 30 °C), between pH 6.5 and 10.5 (optimum pH 7.5) and at a NaCl concentration between 0 and 4 % (w/v) (optimum 0–1 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain J22T belonged to the genus Brevundimonas, with high sequence similarities of >97 % to the sequence of the type strains Brevundimonas alba CB88T, Brevundimonas lenta DS-18T, Brevundimonas variabilis CB17T, Mycoplana bullata TK0051T, Brevundimonas kwangchunensis KSL-102T, Brevundimonas intermedia CB63T, Brevundimonas subvibrioides CB81T and Brevundimonas bacteroides CB7T. Strain J22T exhibited DNA–DNA relatedness values of less than 22.2 % with the phylogenetically related species of the genus Brevundimonas. The DNA G+C content of strain J22T was 66.3 mol%. The predominant cellular fatty acids were C18 : 1 ω7c, C16 : 0 and C16 : 1 ω9c; C12 : 0 3-OH was present, which chemotaxonomically characterizes the members of the genus Brevundimonas. Phylogenetic, genomic and biochemical characteristics served to differentiate this isolate from recognized members of the genus Brevundimonas. Strain J22T (=KCTC 22177T=JCM 15911T) should be classified as a novel species in the genus Brevundimonas, for which the name Brevundimonas basaltis sp. nov. is proposed.

A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated, non-gliding and rod-shaped bacterial strain, SSK2-2T, was isolated from the place where the ocean and a freshwater spring meet at Jeju island, South Korea. Strain SSK2-2T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain SSK2-2T fell within the clade comprising the type strains of species of the genus Maribacter, joining the type strain of Maribacter sedimenticola with which it shared 99.4 % similarity. Sequence similarities to the type strains of other Maribacter species were 94.6–98.2 %. Strain SSK2-2T contained MK-6 as the predominant menaquinone and iso-C17 : 0 3-OH, iso-C15 : 0, iso-C15 : 1 G, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0) as the major fatty acids. The major polar lipids of strain SSK2-2T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain SSK2-2T was 38.2 mol% and mean levels of DNA–DNA relatedness with the type strains of four phylogenetically related species of the genus Maribacter were 11–24 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain SSK2-2T is separate from other Maribacter species. On the basis of the data presented, strain SSK2-2T is considered to represent a novel species of the genus Maribacter, for which the name Maribacter confluentis sp. nov. is proposed. The type strain is SSK2-2T ( = KCTC 42604T = CECT 8869T).

A Gram-stain-positive, rod-shaped, non-spore-forming bacterium (strain HLT3-15T) was isolated from the ice tongue surface of the Hailuogou glacier in Szechwan Province, PR China. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain HLT3-15T belonged to the genus Nocardioides. The highest levels of sequence similarities were found with Nocardioides hwasunensis CGMCC 4.6881T and Nocardioides ganghwensis CGMCC 4.6875T (98.5 % and 98.3 %, respectively). However, DNA–DNA relatedness demonstrated that strain HLT3-15T was distinct from its closest phylogenetic neighbours. The major cellular fatty acids of strain HLT3-15T were C17 : 1ω8c and iso-C16 : 0. Strain HLT3-15T contained ll-2,6-diaminopimelic acid as the diamino acid in the cell-wall peptidoglycan and MK-8(H4) as the predominant menaquinone. On the basis of a polyphasic approach, a novel species, Nocardioides glacieisoli sp. nov., is proposed with HLT3-15T ( = CGMCC 1.11097T = NBRC 109781T) as the type strain.
