A novel, Gram-positive, non-motile, endospore-forming and moderately halophilic bacterium, strain GrbiT, was isolated from a traditional Korean fermented seafood. The organism grew optimally in the presence of 10–15 % NaCl, at 37 °C and pH 8.0. The peptidoglycan of the cell wall consisted of meso-diaminopimelic acid, and the predominant menaquinone was MK-7. The major fatty acids of strain GrbiT were iso-C16 : 0 (36.4 %), anteiso-C15 : 0 (30.3 %) and iso-C14 : 0 (18.2 %). The polar lipids were phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid. The genomic DNA G+C content was 42.5 mol%. Strain GrbiT was most closely related to the type strain Lentibacillus kapialis JCM 12580T, with which it shared 97.5 % 16S rRNA gene sequence similarity. The DNA–DNA hybridization value between strains GrbiT and L. kapialis JCM 12580T was 8 %. Based on phenotypic, genotypic and phylogenetic data, strain GrbiT should be classified as a novel species within the genus Lentibacillus, for which the name Lentibacillus jeotgali sp. nov. is proposed. The type strain is GrbiT (=KCTC 13300T=JCM 15795T).

A novel aerobic actinomycete, designated HA11110T, was isolated from a mangrove soil sample collected in Haikou, China. It formed white aerial mycelium and pale yellow substrate mycelium on Gause's synthetic agar no. 1. Scanning electron microscopy revealed that cells of HA11110T produced straight to spiral spore chains with spiny spores. Chemotaxonomic tests showed that the cell wall contained ll-diaminopimelic acid and the major fatty acids were iso-C16 : 0, anteiso-C15 : 0 and iso-C14 : 0.16S rRNA gene sequence similarity showed that strain HA11110T belonged to the genus Streptomyces, most closely related to Streptomyces fenghuangensis GIMN4.003T (99.1 %), Streptomyces nanhaiensis SCSIO 01248T (98.8 %) and Streptomyces radiopugnans R97T (98.8 %). However, DNA–DNA hybridization studies of strain HA11110T with these three closest relatives showed relatedness values of 58.4, 49.7 and 47.2 %, respectively. On the basis of phenotypic and genotypic data, strain HA11110T represents a novel species of the genus Streptomyces, for which the name Streptomyces mangrovi sp. nov. is proposed. The type strain is HA11110T ( = CGMCC 4.7117T = DSM 42113T).

Moderately Halophilic Bacterium

An aerobic, Gram-stain-positive, endospore-forming, rod-shaped and moderately halophilic strain SKP4-6T, was isolated from shrimp paste (Ka-pi) collected from Samut Sakhon Province, Thailand. Phylogenetic analysis revealed that strain SKP4-6T belonged to the genus Halobacillus and was most closely related to Halobacillus salinus JCM 11546T (98.6 %), Halobacillus locisalis KCTC 3788T (98.6 %) and Halobacillus yeomjeoni KCTC 3957T (98.6 %) based on 16S rRNA gene sequence similarity. The digital DNA–DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strain SKP4-6T and its related species were 18.2–19.3 % and 69.84–84.51 %, respectively, which were lower than the threshold recommended for species delineation. The strain grew optimally at 30–40 °C, at pH 7.0 and with 10–15 % (w/v) NaCl. It contained l-Orn–d-Asp in the cell wall peptidoglycan. The DNA G+C content was 44.8 mol%. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The predominant isoprenoid quinone was MK-7. Phosphatidylglycerol and diphosphatidylglycerol were present as major polar lipids. Based on this polyphasic approach, digital DNA–DNA relatedness and ANI values, strain SKP4-6T represents a novel species of the genus Halobacillus , for which the name Halobacillus fulvus sp. nov. is proposed. The type strain is SKP4-6T (=JCM 32624T=TISTR 2595T).

Blastochloris Viridis

A novel Gram-negative, motile, bacteriochlorophyll b-containing purple non-sulfur bacterium, strain JA248T, was isolated from phototrophic enrichments of a yellow–green epilithic biofilm sample collected from Gulmarg, India. The genomic DNA G+C content of strain JA248T was 63.8 mol%. A phylogenetic tree based on 16S rRNA gene sequence analysis showed that strain JA248T had highest similarity to members of the genus Blastochloris and was closely related to Blastochloris sulfoviridis DSM 729T (98.5 % sequence similarity) and Blastochloris viridis DSM 133T (98.4 %) of the class Alphaproteobacteria. Strain JA248T was characterized based on polyphasic taxonomy, and distinct phenotypic and molecular differences based on DNA–DNA hybridization (relatedness of <46.5 % with the two species of the genus Blastochloris), multilocus sequence analysis, and phenotypic and chemotaxonomic evidence separated strain JA248T from other species of the genus Blastochloris. Strain JA248T therefore represents a novel species in the genus Blastochloris, for which the name Blastochloris gulmargensis sp. nov. is proposed. The type strain is JA248T ( = JCM 14795T  = DSM 19786T).

A Gram-positive, yellowish bacterium strain AK-1Twas isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genusAgromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1Twas closely related toAgromyces aurantiacus(98.6%) followed byAgromyces soli(98.3%),Agromyces tropicus(97.6%),Agromyces ulmi(97.3%),Agromyces flavus(97.2%), andAgromyces italicus(97.0%), whereas the sequence similarity values with respect to the otherAgromycesspecies with validly published names were between 95.3 and 96.7 %. However, the DNA-DNA hybridization values obtained between strain AK-1Tand other related strains were well below the threshold that is required for the proposal of a novel species. The DNAG+Ccontent of the strain is 71.8 mol%. The above data in combination with the phenotypic distinctiveness of AK-1Tclearly indicate that the strain represents a novel species, for which the nameAgromyces arachidissp. nov. is proposed. The type strain is AK-1T(=MTCC 10524T= JCM 19251T).

Moderately Halophilic Bacterium

A moderately halophilic, Gram-positive, rod-shaped bacterium (BH030004T) was isolated from a solar saltern in Korea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BH030004T belonged to the genus Pontibacillus. Chemotaxonomic data (DNA G+C content, 42 mol%; major isoprenoid quinone, MK-7; cell-wall type, A1γ-type meso-diaminopimelic acid; major fatty acids, iso-C15 : 0 and anteiso-C15 : 0) also supported the affiliation of the isolate to the genus Pontibacillus. Although the 16S rRNA gene sequence similarity between strain BH030004T and Pontibacillus chungwhensis DSM 16287T was relatively high (99·1 %), physiological properties and DNA–DNA hybridization (about 7 % DNA–DNA relatedness) allowed genotypic and phenotypic differentiation of strain BH030004T from the type strain of P. chungwhensis. Therefore, strain BH030004T represents a novel species of the genus Pontibacillus, for which the name Pontibacillus marinus sp. nov. is proposed. The type strain is BH030004T (=KCTC 3917T=DSM 16465T).

Group 1

Two novel species belonging to the genus Shewanella are described on the basis of a polyphasic taxonomic approach. A total of 40 strains of Gram-negative, psychrotolerant, H2S-producing bacteria were isolated from marine fish (cod and plaice) caught in the Baltic Sea off Denmark. Strains belonging to group 1 (seven strains) were a lactate-assimilating variant of Shewanella morhuae with a G+C content of 44 mol%. The strains of group 2 (33 strains) utilized lactate, N-acetylglucosamine and malate but did not produce DNase or ornithine decarboxylase. Their G+C content was 47 mol%. Phylogenetic analysis of the 16S rRNA gene sequence data placed the two novel species within the genus Shewanella. Group 1 showed greatest sequence similarity with S. morhuae ATCC BAA-1205T (99.9 %). However, gyrB gene sequence analysis and DNA–DNA hybridization differentiated these isolates from S. morhuae, with 95.6 % sequence similarity and less than 57 % DNA relatedness, respectively. Group 2 strains shared more than 99 % 16S rRNA gene sequence similarity with the type strains of Shewanella colwelliana and Shewanella affinis, but gyrB sequence similarity (~85 %) and the results of DNA hybridization (~28 %) indicated that the new isolates represented a novel species. Furthermore, when compared to each other, the type strains of S. colwelliana and S. affinis had almost identical gyrB sequences and significantly high DNA reassociation values (76–83 %), indicating that they belonged to the same species. Based on the conclusions of this study, we propose the novel species Shewanella glacialipiscicola sp. nov. (type strain T147T=LMG 23744T=NBRC 102030T) for group 1 strains and Shewanella algidipiscicola sp. nov. (type strain S13T=LMG 23746T=NBRC 102032T) for group 2 strains, and we propose that Shewanella affinis as a later heterotypic synonym of Shewanella colwelliana.

A moderately halophilic bacterium, strain BH169T, capable of growing at salinities of 3–20 % (w/v) NaCl was isolated from a saline lake in China. Strain BH169T was strictly aerobic, short-rod-shaped and non-motile (non-flagellated). Its major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C15 : 0 and iso-C16 : 0. The genomic DNA G+C content was about 43 mol% and the predominant quinone was MK-7. The cell-wall peptidoglycan was of the A1γ type, containing meso-diaminopimelic acid as the diagnostic diamino acid. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate formed a distinct phylogenetic line within the spore-forming rods of the genus Bacillus. The levels of 16S rRNA gene sequence similarity to the type strains of Bacillus species were below 93 %. On the basis of phenotypic and molecular properties, strain BH169T (=KCTC 3912T=DSM 16461T) represents the type strain of a novel species within the genus Bacillus, for which the name Bacillus salarius sp. nov. is proposed.
