A novel, moderately halophilic, Gram-positive coccus, designated strain S2R53-5T, was isolated from jeotgal, a traditional Korean fermented seafood. The organism was strictly aerobic, non-motile, non-sporulating and catalase- and oxidase-positive. Strain S2R53-5T grew in the presence of 0.5–15 % (w/v) NaCl and at pH 6.5–11.0, with optimum growth at 5 % (w/v) NaCl and pH 7.0. The temperature range for growth was 20.0–30.0 °C, with an optimum temperature of 30 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2R53-5T belongs to the family Staphylococcaceae and was most closely related to Salinicoccus roseus DSM 5351T (96.8 % gene sequence similarity), Salinicoccus hispanicus DSM 5352T (96.1 %), Salinicoccus alkaliphilus T8T (95.2 %) and Jeotgalicoccus halotolerans YKJ-101T (95.1 %). The genomic DNA G+C content was 47.0 mol%, which is in the range of 46–51 mol% that is characteristic for the genus Salinicoccus. Levels of DNA–DNA relatedness between strain S2R53-5T and S. roseus DSM 5351T, S. hispanicus DSM 5352T and S. alkaliphilus KCTC 13928T were 32.2, 15.4 and 4.6 %, respectively. Chemotaxonomic data (major menaquinone, MK-6; major fatty acids, iso-C15 : 0 and anteiso-C15 : 0; cell-wall murein type, Lys and Gly) and 16S rRNA gene sequence analysis supported the affiliation of strain S2R53-5T with the genus Salinicoccus. The combined evidence from the low DNA–DNA relatedness, physiological, biochemical and other genotypic data indicate that strain S2R53-5T clearly represents a novel species of the genus Salinicoccus, for which the name Salinicoccus jeotgali sp. nov. is proposed. The type strain is S2R53-5T (=KCTC 13030T=LMG 23640T).

A halotolerant, Gram-negative, rod-shaped and light-red-pigmented bacterium, designated LP51T, was isolated from pond sediment near a hexachlorocyclohexane dumpsite located at Chinhat, Lucknow, India. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain LP51T formed a distinct phyletic clade along with the members of the genus Pontibacter. The 16S rRNA gene sequence similarity to members of the genus Pontibacter ranged from 94.2 to 99.4  %. The cells were motile, aerobic and catalase- and oxidase-positive. The major fatty acids were iso-C15  :  0 (17.8  %), iso-C15  :  0 3-OH (8.8  %), iso-C17  :  0 3-OH (5.7  %), summed feature 3 (C16  :  1ω7c and/or C16  :  1ω6c; 6.5  %) and summed feature 4 (iso-C17  :  1 I and/or anteiso-C17  :  1 B; 30.7  %). The polar lipid profile of strain LP51T showed the presence of phosphatidylethanolamine, an unidentified aminophospholipid, unknown aminolipids, unknown polar lipids and unknown glycolipids. DNA–DNA relatedness of strain LP51T with respect to the most closely related type strain, Pontibacter korlensis X14-1T, was 47.2  %. On the basis of this information, it is proposed that the isolate be assigned to a novel species of the genus Pontibacter, for which the name Pontibacter chinhatensis sp. nov. is proposed.

Emended Description

A Gram-stain-negative, non-flagellated, motile (by gliding), yellow-pigmented, rod-shaped bacterial strain, designated L-4T, was isolated from seawater of Baekdo harbour in the East Sea, Korea. Strain L-4T grew optimally at 37 °C, at pH 6.5–7.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain L-4T clustered with Olleya marilimosa CAM030T, a member of the family Flavobacteriaceae. Strain L-4T exhibited 16S rRNA gene sequence similarity values of 97.2 % to O. marilimosa CAM030T and less than 95.8 % to other members of the family Flavobacteriaceae. Strain L-4T and O. marilimosa CIP 108537T contained MK-6 as the predominant menaquinone. The fatty acid and polar lipid profiles of strain L-4T were similar to those of O. marilimosa CIP 108537T. The DNA G+C content of strain L-4T was 35 mol% and DNA–DNA relatedness between strain L-4T and O. marilimosa CIP 108537T was 7 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, enable strain L-4T to be distinguished from O. marilimosa. On the basis of these data, strain L-4T is considered to represent a novel species of the genus Olleya for which the name Olleya aquimaris sp. nov. is proposed; the type strain is L-4T (=KCTC 22661T =CCUG 58074T). An emended description of the genus Olleya is also provided.

Two novel heterotrophic, facultatively anaerobic, gliding and yellow-pigmented bacteria, designated strains KMM 6270T and KMM 6320, were isolated from different marine environments and studied using a polyphasic taxonomic approach. 16S rRNA gene sequence analysis placed the strains within the family Flavobacteriaceae. Strains KMM 6270T and KMM 6320 were most closely related to the type strains of recognized species of the genus Salinimicrobium (95.0–96.6 % 16S rRNA gene sequence similarity). The G+C content of the genomic DNA was 40–41 mol%. The strains grew with 0.5–15 % (w/v) NaCl (optimum 4 % NaCl) and at 4–41 °C (optimum 28–32 °C). Aesculin and gelatin were hydrolysed, but agar, casein, DNA and chitin were not. The phylogenetic data taken together with the results of the genotypic and phenotypic studies permit the classification of strains KMM 6270T and KMM 6320 as members of a novel species of the genus Salinimicrobium, for which the name Salinimicrobium marinum sp. nov. is proposed. The type strain is KMM 6270T (=KCTC 12719T=LMG 25395T).

© 2017 IUMS. A novel anaerobic pectinolytic bacterium (strain 14T) was isolated from human faeces. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 14T belonged to the family Ruminococcaceae, but was located separately from known clostridial clusters within the taxon. The closest cultured relative of strain 14T was Acetivibrio cellulolyticus (89.7% sequence similarity). Strain 14T shared ~99% sequence similarity with cloned 16S rRNA gene sequences from uncultured bacteria derived from the human gut. Cells were Gram-stain-positive, non-motile cocci approximately 0.6μm in diameter. Strain 14T fermented pectins from citrus peel, apple, and kiwifruit as well as carbohydrates that are constituents of pectins and hemicellulose, such as galacturonic acid, xylose, and arabinose. TEM images of strain 14T, cultured in association with plant tissues, suggested extracellular fibrolytic activity associated with the bacterial cells, forming zones of degradation in the pectin-rich regions of middle lamella. Phylogenetic and phenotypic analysis supported the differentiation of strain 14T as a novel genus in the family Ruminococcaceae. The name Monoglobus pectinilyticus gen. nov., sp. nov. is proposed; the type strain is 14T (JCM 31914T=DSM 104782T).
