Five strains with strong chitinolytic activity were isolated from a soil sample collected from southern Taiwan. The strains shared more than 92 % DNA–DNA similarity, indicating membership of the same genospecies. This close relationship was supported by high similarities in fatty acid composition and biochemical characteristics. A 16S rRNA gene sequence analysis indicated that the isolates were members of the class ‘Betaproteobacteria’, in which they formed an individual subline of descent that was distantly related (<94 % similarity) to lineages defined by Formivibrio citricus DSM 6150T and Iodobacter fluviatilis DSM 3764T. On the basis of the phylogenetic and phenotypic distinctness of these novel chitin-degrading organisms, a new genus, Chitinibacter, is proposed, with Chitinibacter tainanensis (type strain, S1T=BCRC 17254T=DSM 15459T) as the type species.

Three novel heterotrophic, Gram-negative, yellow-pigmented, aerobic, gliding, oxidase- and catalase-positive bacteria were isolated from algae collected in the Gulf of Peter the Great, Sea of Japan. 16S rRNA gene sequence analysis revealed that the strains studied represented members of the family Flavobacteriaceae and showed 93·5–93·8 % similarity with their closest relative, Psychroserpens burtonensis. The DNA G+C content of the strains was 34–37 mol%. The major respiratory quinone was MK-6. The predominant fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C15 : 1, iso-C16 : 0-3OH and iso-C17 : 0-3OH. On the basis of their phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the newly described bacteria have been assigned to the new genus Winogradskyella gen. nov., as Winogradskyella thalassocola sp. nov. (type strain, KMM 3907T=KCTC 12221T=LMG 22492T=DSM 15363T), Winogradskyella epiphytica sp. nov. (type strain, KMM 3906T=KCTC 12220T=LMG 22491T=CCUG 47091T) and Winogradskyella eximia sp. nov. (type strain, KMM 3944T (=KCTC 12219T=LMG 22474T).

Five Gram-negative, motile, spiral-shaped strains were isolated from a sulfide spring (D-412T), active sludge of wastewater (D-419T, D-420, D-424) and industrial wastewater (D-416). Comparative 16S rRNA gene sequence analysis showed that the isolates belong to the family Comamonadaceae, within the class Betaproteobacteria, but fall into a distinct cluster. On the basis of phenotypic, chemotaxonomic and phylogenetic data, a new genus, Giesbergeria gen. nov., is proposed, including five species. The type species of the genus is Giesbergeria voronezhensis sp. nov. (type strain D-419T=DSM 12825T=CIP 107340T=VKM B-2350T) and other novel members of the genus are Giesbergeria kuznetsovii sp. nov. (type strain D-412T=DSM 12827T=VKM B-2352T), Giesbergeria giesbergeri comb. nov. (basonym Aquaspirillum giesbergeri), Giesbergeria sinuosa comb. nov. (basonym Aquaspirillum sinuosum) and Giesbergeria anulus comb. nov. (basonym Aquaspirillum anulus). Using the same criteria, isolate D-416 (=DSM 12826) was identified as a strain of [Aquaspirillum] metamorphum. Strain D-416, the type strain of [A.] metamorphum and the type strain of [Aquaspirillum] psychrophilum form a distinct cluster within the family Comamonadaceae (97–97·2 % 16S rRNA gene sequence similarity) and share phenotypic and chemotaxonomic properties. Therefore, it is proposed that these strains are reclassified as members of a new genus, Simplicispira gen. nov., as Simplicispira metamorpha comb. nov. (the type species) and Simplicispira psychrophila comb. nov., respectively.

In the course of phylogenetic analyses of the taxa within the suborder Pseudonocardineae, it was observed that Saccharothrix tangerinus MK27-91F2T was misplaced in the genus Saccharothrix. After a detailed examination of nucleotide signatures in the 16S rRNA gene sequence along with the morphological and chemotaxonomic characteristics of this strain, which are different from those of all species of Saccharothrix as well as the other genera within the suborder, it was concluded that this strain represents a new genus, for which the name Umezawaea gen. nov. is proposed. Pseudosporangia are produced on the aerial mycelium, the whole-cell sugar pattern consists of galactose, mannose and ribose, phosphatidylethanolamine, phosphatidylinositol and lyso-phosphatidylethanolamine are the predominant phospholipids and MK-9(H4) is the predominant menaquinone. The type species of the proposed new genus is Umezawaea tangerina gen. nov., comb. nov., with the type strain MK27-91F2T (=NRRL B-24463T =DSM 44720T =FERM P-16053T =JCM 10302T =NBRC 16184T).

Sixty-two strains of thermophilic aerobic endospore-forming bacteria were subjected to polyphasic taxonomic study including 16S rRNA gene sequence analysis, polar lipid and fatty acid analysis, phenotypic characterization, and DNA–DNA hybridization experiments. Distinct clusters of the species Geobacillus stearothermophilus , Geobacillus thermodenitrificans , Geobacillus toebii and Geobacillus thermoglucosidasius were formed, allowing their descriptions to be emended, and the distinctiveness of the poorly represented species Geobacillus jurassicus , Geobacillus subterraneus and Geobacillus caldoxylosilyticus was confirmed. It is proposed that the name Geobacillus thermoglucosidasius be corrected to Geobacillus thermoglucosidans nom. corrig. Bacillus thermantarcticus clustered between Geobacillus species on the basis of 16S rRNA gene sequence analysis, and its transfer to the genus Geobacillus as Geobacillus thermantarcticus comb. nov. (type strain LMG 23032T = DSM 9572T = strain M1T = R-35644T) is proposed. The above-mentioned species, together with Geobacillus thermoleovorans and Geobacillus thermocatenulatus , form a monophyletic cluster representing the genus Geobacillus . The distinctiveness of ‘Geobacillus caldoproteolyticus’ was confirmed and it is proposed that it be accommodated, along with Geobacillus tepidamans , in the genus Anoxybacillus as Anoxybacillus caldiproteolyticus sp. nov. (type strain DSM 15730T = ATCC BAA-818T = LMG 26209T = R-35652T) and Anoxybacillus tepidamans comb. nov. (type strain LMG 26208T = ATCC BAA-942T = DSM 16325T = R-35643T), respectively. The type strain of Geobacillus debilis was not closely related to any members of the genera Anoxybacillus and Geobacillus , and it is proposed that this species be placed in the new genus Caldibacillus as Caldibacillus debilis gen. nov. comb. nov. The type strain of the type species, Caldibacillus debilis, is LMG 23386T ( = DSM 16016T = NCIMB 13995T = TfT = R-35653T).

A Gram-stain-positive, rod-shaped, spore-forming and strictly anaerobic bacterium, designated UB-B.2T, was isolated from an industrial effluent anaerobic digester sample. It grew optimally at 30 °C and pH 7.0. Comparative analysis of the 16S rRNA gene sequence confirmed that strain UB-B.2T was closely related to Clostridium hathewayi DSM 13479T (97.84 % similarity), a member of rRNA gene cluster XIVa of the genus Clostridium , and formed a coherent cluster with other related members of the Blautia ( Clostridium ) coccoides rRNA group in phylogenetic analyses. The end products of glucose fermentation by strain UB-B.2T were acetate and propionate. The G+C content of the DNA was 51.4 mol%. Although strain UB-B.2T showed 97.8 % 16S rRNA gene sequence identity to the type strain of C. hathewayi , it exhibited only 38.4 % relatedness at the whole-genome level. It also showed differences from its closest phylogenetic relative, C. hathewayi DSM 13479T, in phenotypic characteristics such as hydrolysis of aesculin, starch and urea and fermentation end products. Both strains showed phenotypic differences from the members of rRNA gene cluster XIVa of the genus Clostridium . Based on these differences, C. hathewayi DSM 13479T and strain UB-B.2T were identified as representatives of a new genus of the family Clostridiaceae . Thus, we propose the reclassification of Clostridium hathewayi as Hungatella hathewayi gen. nov., comb. nov., the type species of the new genus (type strain DSM 13479T = CCUG 43506T = MTCC 10951T). Strain UB-B.2T ( = MTCC 11101T = DSM 24995T) is assigned to the novel species Hungatella effluvii gen. nov., sp. nov as the type strain.

The reclassification of Leptotrichia goodfellowii as Pseudoleptotrichia goodfellowii gen. nov., comb. nov. is proposed because of the separate phylogenetic position on the basis of the results of 16S rRNA gene sequence analysis, the genomic differences from all other Leptotrichia species and phenotypic differences from Leptotrichia species. The species Pseudoleptotrichia goodfellowii is the type species of the genus. The type strain is LB 57T, CCUG 32286 T, DSM 19756T.

A Gram-stain-negative bacterial strain, 10-17T, was isolated from traditional sourdough in Heilongjiang Province, China. The bacterium was characterized by a polyphasic approach, including 16S rRNA gene sequence analysis, RNA polymerase β subunit (rpoB) gene sequence analysis, DNA gyrase (gyrB) gene sequence analysis, initiation translation factor 2 (infB) gene sequence analysis, ATP synthase β subunit (atpD) gene sequence analysis, fatty acid methyl ester analysis, determination of DNA G+C content, DNA–DNA hybridization and an analysis of phenotypic features. Strain 10-17T was phylogenetically related to Enterobacter hormaechei CIP 103441T, Enterobacter cancerogenus LMG 2693T, Enterobacter asburiae JCM 6051T, Enterobacter mori LMG 25706T, Enterobacter ludwigii EN-119T and Leclercia adecarboxylata LMG 2803T, having 99.5 %, 99.3 %, 98.7 %, 98.5 %, 98.4 % and 98.4 % 16S rRNA gene sequence similarity, respectively. On the basis of polyphasic characterization data obtained in the present study, a novel species, Enterobacter xiangfangensis sp. nov., is proposed and the type strain is 10-17T ( = LMG 27195T = NCIMB 14836T = CCUG 62994T). Enterobacter sacchari Zhu et al. 2013 was reclassified as Kosakonia sacchari comb. nov. on the basis of 16S rRNA, rpoB, gyrB, infB and atpD gene sequence analysis and the type strain is strain SP1T( = CGMCC 1.12102T = LMG 26783T).

An aerobic, Gram-negative, rod-shaped bacterium with polar flagella, strain CC-AFH3T, was isolated from an oil-contaminated site located in Kaohsiung county, Taiwan. Strain CC-AFH3T grew at 20–40 °C, pH 5.0–10.0 and <2 % (w/v) NaCl. 16S rRNA gene sequence analysis indicated that strain CC-AFH3T showed the greatest degree of similarity to Herbaspirillum soli SUEMI10T (96.5 %), H. aurantiacum SUEMI08T (96.3 %), H. canariense SUEMI03T (96.0 %), H. psychrotolerans PB1T (95.4 %) and members of other Herbaspirillum species (94.1–95.2 %), and lower similarity to members of other genera (<94 %). Phylogenetic analyses also positioned the novel strain in the genus Herbaspirillum as an independent lineage. The major fatty acids in strain CC-AFH3T were C10 : 0 3-OH, C12 : 0, C14 : 0 2-OH, C16 : 0, iso-C15 : 0 3-OH, C17 : 0 cyclo, C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c. The major polar lipids of strain CC-AFH3T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine. The predominant quinone was ubiquinone 8 (Q-8) and the DNA G+C content was 63.4 mol%. On the basis of 16S rRNA gene sequence analysis in combination with physiological and chemotaxonomic data, strain CC-AFH3T represents a novel species in a new genus, for which we propose the name Noviherbaspirillum malthae gen. nov., sp. nov.; the type strain of Noviherbaspirillum malthae is CC-AFH3T ( = BCRC 80516T = JCM 18414T). We also propose the reclassification of Herbaspirillum soli , Herbaspirillum aurantiacum , Herbaspirillum canariense and ‘Herbaspirillum psychrotolerans’ as Noviherbaspirillum soli comb. nov. (type strain SUEMI10T = LMG 26149T = CECT 7840T), Noviherbaspirillum aurantiacum comb. nov. (type strain SUEMI08T = LMG 26150T = CECT 7839T), Noviherbaspirillum canariense comb. nov. (type strain SUEMI03T = LMG 26151T = CECT 7838T) and Noviherbaspirillum psychrotolerans comb. nov. (type strain PB1T = DSM 26001T = LMG 27282T), respectively. An emended description of Herbaspirillum seropedicae is also presented.

A cream-coloured, Gram-stain-negative, aerobic, non-motile, rod- to irregular shaped bacterium, strain 119/4T, was isolated from a choana swab of a white stork nestling on sheep blood agar. 16S rRNA gene sequence analysis and subsequent comparisons showed that it was a member of the family Rhodobacteraceae, showing 94.9 % similarity to the type strain of Gemmobacter tilapiae and 94.6 % similarity to that of Gemmobacter nectariphilus , but also similarly low sequence similarity to the type strains of Rhodobacter viridis (94.8 %), Rhodobacter veldkampii (94.6 %) and Paenirhodobacter enshiensis (94.6 %). Reconstruction of phylogenetic trees showed that strain 119/4T clustered close to species of the genus Gemmobacter . The quinone system contained high amounts of ubiquinone Q-10 with traces of Q-8, Q-9 and Q-11, and the fatty acid profile consisted mainly of C18 : 1ω7c, C16 : 1ω7c/iso-C15 : 0 2-OH and C10 : 0 3-OH. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phoshatidylglycerol and phosphatidylcholine. Major polyamines were putrescine and spermidine. On the basis of 16S rRNA gene sequence analysis and chemotaxonomic and physiological data, strain 119/4T represents a novel species of the genus Gemmobacter , for which the name Gemmobacter intermedius sp. nov. is proposed. The type strain is 119/4T ( = CIP 110795T = LMG 28215T = CCM 8510T).

As part of a study of the diversity of planctomycetes, two novel strains, designated OJF2T and OJF8, were isolated from the sediments of a freshwater aquarium. The organisms were chemoheterotrophic, spherical and pink-pigmented, had an optimum growth temperature of about 30–35 °C and an optimum pH for growth of around 7.5–8.5. The predominant fatty acids were C18 : 1ω9c and C16 : 0. The two strains were able to assimilate several sugars and organic acids. 16S rRNA gene sequence analysis confirmed the affiliation of these organisms to the phylum ‘Planctomycetes’; they showed highest similarity to the type strains of Singulisphaera acidiphila (92.4 %) and Isosphaera pallida (91.9 %). On the basis of physiological, biochemical and chemotaxonomic characteristics, strains OJF2T and OJF8 are considered to represent a novel species of a new genus of the order Planctomycetales, for which the name Aquisphaera giovannonii gen. nov., sp. nov. is proposed. The type strain of Aquisphaera giovannonii is OJF2T ( = CECT 7510T  = DSM 22561T).
