A novel facultatively methylotrophic, Gram-negative, rod-shaped bacterium, designated strain S2R03-9T, was isolated from jeotgal, a traditional Korean fermented seafood. The organism was strictly aerobic, motile by means of a single polar flagellum, non-sporulating and catalase- and oxidase-positive. Strain S2R03-9T grew in the presence of 0–1 % (w/v) NaCl and at pH 6.0–10.0, with optimum growth in the absence of NaCl and at pH 7.0. It grew at temperatures in the range 20.0–30.0 °C, with optimum growth at 30 °C. Colonies grown on R2A medium were non-pigmented, opaque and creamy white. Phylogenetic analysis based on 16S rRNA gene sequences indicated that it was most closely related to Methylobacterium organophilum JCM 2833T (96.6 % similarity) and the phylogenetic similarities to all other Methylobacterium species with validly published names were less than 95.0 %. The DNA G+C content was 64.9 mol%. The phylogenetic analysis, the phenotypic assessment and the chemotaxonomic data (major ubiquinone, Q-10; major fatty acids, C18 : 1 and C18 : 0) showed that S2R03-9T represents a novel species within the genus Methylobacterium in the class Alphaproteobacteria, for which the name Methylobacterium jeotgali sp. nov. is proposed. The type strain is S2R03-9T (=KCTC 12671T=LMG 23639T).

A light-pink-coloured bacterium, designated strain 5416T-32T, was isolated from an air sample in Korea. Cells of the strain were strictly aerobic, Gram-negative, motile (single polar or subpolar flagellum) and rod-shaped. Optimal growth occurred at 25–30 °C and at pH 6.0–7.0. The major quinones were Q-10 and Q-8. The major fatty acids were C18 : 1 ω7c (53.8 %) and C16 : 0 (15.9 %). The G+C content of the genomic DNA was 65.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 5416T-32T was most closely related to Skermanella parooensis, with a similarity of 96.2 %, but relatively low sequence similarities (<92 %) were found with respect to other species with validly published names held in GenBank. Phenotypic and genotypic analyses indicated that strain 5416T-32T could not be assigned to any recognized species. Therefore strain 5416T-32T represents a novel species of the genus Skermanella, for which the name Skermanella aerolata sp. nov. is proposed. The type strain is 5416T-32T (=KACC 11604T=DSM 18479T).

Two sporulating bacterial strains designated CECAP06T and CECAP16 were isolated from the rhizosphere of the legume Cicer arietinum in Argentina. Almost-complete 16S rRNA gene sequences identified the isolates as a Paenibacillus species. It was most closely related to Paenibacillus cineris LMG 18439T (99·6 % sequence similarity), Paenibacillus favisporus LMG 20987T (99·4 % sequence similarity) and Paenibacillus azoreducens DSM 13822T (97·7 % sequence similarity). The cells of this novel species were motile, sporulating, rod-shaped, Gram-positive and strictly aerobic. The predominant fatty acids were anteiso-C15 : 0, C16 : 0 and iso-C16 : 0. The DNA G+C content of strains CECAP06T and CECAP16 was 51·3 and 50·9 mol%, respectively. Growth was observed from many carbohydrates, but gas production was not observed from glucose. Catalase and oxidase activities were present. The isolates produced β-galactosidase and hydrolysed aesculin. Gelatinase, caseinase and urease were not produced. The results of DNA–DNA hybridization showed that the strains from this study constitute a novel species of the genus Paenibacillus, for which the name Paenibacillus rhizosphaerae sp. nov. is proposed. The type strain is CECAP06T (=LMG 21955T=CECT 5831T).

An orange-pigmented bacterium, designated strain 13-9-B8T, was isolated from a seawater sample collected at Marado, Jeju Island, South Korea. The novel strain was Gram-staining-negative, non-motile, non-gliding, rod-shaped and aerobic. A phylogenetic analysis based on 16S rRNA gene sequences revealed that the strain clustered with members of the genus Lewinella of the family Saprospiraceae in the phylum Bacteroidetes and was most closely related to the species Lewinella marina (95.6 % similarity to the type strain). Strain 13-9-B8T grew optimally at 30 °C, pH 7.0 and with 2 % (w/v) NaCl. Strain 13-9-B8T contained MK-7 as the predominant menquinone and summed feature 3, iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The polar lipids detected in strain 13-9-B8T were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and eight unidentified lipids. The DNA G+C content of strain 13-9-B8T was 59.1 mol%. Based on phenotypic, chemotaxonomic and phylogenetic data presented, strain 13-9-B8T is considered to represent a novel species of the genus Lewinella, for which the name Lewinella xylanilytica sp. nov. is proposed. The type strain is 13-9-B8T ( = DSM 29526T = KCTC 32663T).

A sponge-associated strain, KMM 7019T, was investigated in a polyphasic taxonomic study. The bacterium was strictly aerobic, heterotrophic, Gram-negative, yellow-pigmented, motile by gliding and oxidase-, catalase-, β-galactosidase- and alkaline phosphatase-positive. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain KMM 7019T is closely related to members of the genus Salegentibacter, namely Salegentibacter holothuriorum, Salegentibacter mishustinae and Salegentibacter salegens (97·7–98 % sequence similarities). The DNA–DNA relatedness between the strain studied and Salegentibacter species ranged from 27 to 31 %, clearly demonstrating that KMM 7019T belongs to a novel species of the genus Salegentibacter, for which the name Salegentibacter agarivorans sp. nov. is proposed. The type strain is KMM 7019T (=KCTC 12560T=LMG 23205T).
