A coryneform strain, 06-1773OT (=WAL 19168T), derived from a groin abscess sample was characterized using phenotypic and molecular taxonomic methods. Comparative analyses revealed more than 3 % divergence of the 16S rRNA gene sequence and about 10 % divergence of the partial rpoB gene sequence from the type strain of Corynebacterium glucuronolyticum. The strain could also be differentiated from C. glucuronolyticum by a set of phenotypic properties. A DNA–DNA relatedness study between strain WAL 19168T and C. glucuronolyticum CCUG 35055T showed a relatedness value of 13.3 % (13.7 % on repeat analysis). The genotypic and phenotypic data show that the strain merits classification within a novel species of Corynebacterium. We propose the name Corynebacterium pyruviciproducens sp. nov. for the novel species. The type strain is 06-1773OT (=WAL 19168T =CCUG 57046T =ATCC BAA-1742T).

The taxonomic position of an actinomycete isolated from a brown hypermagnesian ultramafic soil was examined using a polyphasic approach. The organism, which was designated SBHS Strp1T, was found to have chemical and morphological properties typical of Amycolatopsis strains. It was most closely associated with Amycolatopsis kentuckyensis, Amycolatopsis lexingtonensis, Amycolatopsis rifamycinica, Amycolatopsis pretoriensis and Amycolatopsis tolypomycina on the basis of 16S rRNA gene sequence data, and showed a unique pattern of phenotypic properties that distinguished it from the type strains of these taxa. The combined genotypic and phenotypic data show that the organism merits description as a novel species of Amycolatopsis. The name proposed for the novel species is Amycolatopsis plumensis sp. nov.; the type strain is SBHS Strp1T (=DSM 44776T=NRRL B-24324T).

Comparative 16S rRNA gene sequence analysis indicates that two distinct sublineages exist within the genus Alcaligenes: the Alcaligenes faecalis lineage, comprising Alcaligenes aquatilis and A. faecalis (with the three subspecies A. faecalis subsp. faecalis, A. faecalis subsp. parafaecalis and A. faecalis subsp. phenolicus), and the Alcaligenes defragrans lineage, comprising A. defragrans. This phylogenetic discrimination is supported by phenotypic and chemotaxonomic differences. It is proposed that the A. defragrans lineage constitutes a distinct genus, for which the name Castellaniella gen. nov. is proposed. The type strain for Castellaniella defragrans gen. nov., comb. nov. is 54PinT (=CCUG 39790T=CIP 105602T=DSM 12141T). Finally, on the basis of data from the literature and new DNA–DNA hybridization and phenotypic data, the novel species Castellaniella denitrificans sp. nov. (type strain NKNTAUT=DSM 11046T=CCUG 39541T) is proposed for two strains previously identified as strains of A. defragrans.

Two bacterial strains isolated from different hospitals in Japan were subjected to a polyphasic analysis. Strains IFM 0803T and IFM 10383 were found to have morphological, biochemical, physiological and chemotaxonomic properties consistent with their classification in the genus Nocardia. Strains IFM 0803T and IFM 10383 clustered with the type strain of Nocardia xishanensis, showing 16S rRNA gene sequence similarities of 98.6–98.9 % with this species. The novel strains could be distinguished from N. xishanensis by a range of phenotypic properties. Based on their phenotypic and phylogenetic characteristics, the two isolates are proposed as members of a novel species of the genus Nocardia, Nocardia exalbida sp. nov., with the type strain IFM 0803T (=NBRC 100660T=JCM 12667T=DSM 44883T).

A yellow-coloured, aerobic, Gram-negative, rod-shaped bacterial strain, designated B-IT, was isolated from the water of a shrimp (Litopenaeus vannamei) mariculture pond in Taiwan. No species with a validly published name showed 16S rRNA gene sequence similarity of more than 96.5 % to this novel isolate. The highest sequence similarities displayed by strain B-IT (93.2–96.1 %) were to members of the genus Tenacibaculum. The phenotypic properties of this organism were consistent with its classification in the genus Tenacibaculum. The novel isolate could be distinguished from all Tenacibaculum species by several phenotypic characteristics. The major fatty acids were iso-C15 : 0 (22 %), summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH; 21.3 %), iso-C17 : 0 3-OH (12.7 %) and iso-C15 : 1 (8.7 %). The G+C content of the genomic DNA was 35.2 mol%. Hence, genotypic and phenotypic data demonstrate that strain B-IT should be classified within a novel species in the genus Tenacibaculum, for which the name Tenacibaculum litopenaei sp. nov. is proposed. The type strain is B-IT (=BCRC 17590T=LMG 23706T).

A Gram-negative, non-motile and rod-, oval- or coccoid-shaped bacterial strain, DSW-25T, which is phylogenetically closely related to the genera Staleya and Sulfitobacter, was isolated from seawater of the East Sea, Korea, and subjected to a polyphasic taxonomic study. Strain DSW-25T grew optimally at pH 7.0–8.0 and at 25 °C. It contained Q-10 as the predominant ubiquinone and C18 : 1 ω7c as the major fatty acid. Major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The DNA G+C content was 56.9 mol%. Strain DSW-25T exhibited 16S rRNA gene sequence similarity values of 98.4 % to the type strain of Staleya guttiformis and of 96.6–97.6 % to Sulfitobacter species. There were no distinct phenotypic, particularly chemotaxonomic, properties to differentiate Staleya guttiformis and strain DSW-25T from the genus Sulfitobacter. DNA–DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain DSW-25T differs from recognized Sulfitobacter species and Staleya guttiformis. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strain DSW-25T was classified in the genus Sulfitobacter as a member of a novel species, for which the name Sulfitobacter donghicola sp. nov. is proposed. The type strain is strain DSW-25T (=KCTC 12864T =JCM 14565T). It is also proposed that Staleya guttiformis be transferred to the genus Sulfitobacter as Sulfitobacter guttiformis comb. nov.

A Gram-reaction-positive, rod-shaped, spore-forming bacterium, designated Gsoil 1105T, was isolated from soil of a ginseng field in Pocheon Province in South Korea and characterized in order to determine its taxonomic position. Comparative analysis of the 16S rRNA gene sequence showed that the isolate belongs to the order Bacillales, showing the highest level of sequence similarity with respect to Tumebacillus permanentifrigoris Eur1 9.5T (94.6 %). The phylogenetic distances from other described species with validly published names within the order Bacillales were greater than 9.0 %. Strain Gsoil 1105T had a genomic DNA G+C content of 55.6 mol% and menaquinone 7 (MK-7) as the major respiratory quinone. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1105T represents a novel species of the genus Tumebacillus, for which the name Tumebacillus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 1105T ( = KCTC 13942T  = DSM 18389T).

A novel actinomycete, designated strain 06182M-1T, was isolated from a mangrove soil sample collected from Chiayi County in Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences revealed levels of similarity of 97.0–98.8 % to the type strains of recognized species of the genus Isoptericola. Chemotaxonomic data also supported the placement of strain 06182M-1T within the genus Isoptericola. However, the low levels of DNA–DNA relatedness between the novel strain and the type strains of recognized species of the genus Isoptericola, in combination with differential phenotypic data, demonstrate that strain 06182M-1T represents a novel species of the genus Isoptericola, for which the name Isoptericola chiayiensis sp. nov. is proposed. The type strain is 06182M-1T ( = BCRC 16888T  = KCTC 19740T).

Strain DSM 44594T, which produces the glycopeptide antibiotic decaplanin, is a member of the genus Amycolatopsis based on 16S rRNA gene sequence analysis and chemotaxonomic properties. It is the first member of this genus that is reported to form pseudosporangia, which resemble those of members of the genus Kibdelosporangium. Phylogenetically, the novel taxon is related to Amycolatopsis orientalis, Amycolatopsis lurida, Amycolatopsis azurea, Amycolatopsis japonica and Amycolatopsis keratiniphila. Morphological, cultural and physiological properties, the production of a unique glycolipid and DNA–DNA similarity of <55 % with phylogenetically related strains reveal that strain DSM 44594T represents a novel species of the genus, for which the name Amycolatopsis decaplanina sp. nov. (type strain, FH 1845T=DSM 44594T=NRRL B-24209T) is proposed.

Two yellow-pigmented, Gram-negative, rod-shaped bacterial strains, GH1-10T and GH29-5T, were isolated from greenhouse soils in Korea. 16S rRNA gene sequence analysis indicated that these strains were related to members of the genus Flavobacterium. Strain GH1-10T was most closely related to Flavobacterium psychrolimnae and Flavobacterium denitrificans, with sequence similarities of 95.9 and 95.2 %, respectively. Strain GH29-5T was most closely related to ‘Flavobacterium saliodium’, F. denitrificans and Flavobacterium frigoris, with sequence similarities of 94.3, 92.5 and 92.5 %, respectively. The major cellular fatty acids of GH1-10T were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c) and iso-C17 : 0 3-OH, and those of GH29-5T were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. Both strains contained menaquinone with six isoprene units (MK-6) as the sole quinone. The DNA G+C contents of GH1-10T and GH29-5T were 35 and 39 mol%, respectively. Based on the phylogenetic and phenotypic data presented, it is concluded that the two bacteria represent two separate novel species of the genus Flavobacterium. The names proposed to accommodate these organisms are Flavobacterium daejeonense sp. nov., with type strain GH1-10T (=KACC 11422T=DSM 17708T), and Flavobacterium suncheonense sp. nov., with type strain GH29-5T (=KACC 11423T=DSM 17707T).

A Gram-negative, rod-shaped bacterial strain, designated K19414T, was isolated from a chironomid (Diptera; Chironomidae) egg mass which was sampled from Kishon River in northern Israel. Phylogenetic analysis based on the 16S rRNA gene sequence positioned the novel strain among the genus Rheinheimera, with closest similarity to Rheinheimera pacifica KMM 1406T. The levels of similarity to type strains of Rheinheimera species were lower than 96.5 %. Isolate K19414T is aerobic, motile by means of a single polar flagellum, catalase-negative and oxidase-positive; growth was observed at salinities of 0–2 % NaCl and the temperature for growth ranged from 4 to 40 °C. The major cellular fatty acids are 16 : 0 (14.8 %) and 16 : 1ω7c and/or 15 : 0 iso 2-OH (25.76 %). The DNA G+C content is 49.9 mol%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain K19414T (=LMG 23818T =DSM 18694T) was classified in the genus Rheinheimera as the type strain of a novel species, for which the name Rheinheimera chironomi sp. nov. is proposed.
