Bacterium Strain

A Gram-stain-negative, rod-shaped bacterium, strain SW112T, was isolated from a seawater sample collected from the Indian Ocean. The strain was strictly aerobic and catalase- and oxidase-positive. Strain SW112T grew at 4–42 °C (optimum 30 °C), at pH 5.5–9.5 (optimum pH 7.5) and in the presence of 0–9.0 % (w/v) NaCl (optimum 2.0–3.0 %). The predominant cellular fatty acids were iso-C15 : 0 (29.7 %), iso-C17 : 03-OH (14.3 %) and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c, 15.1 %). The major menaquinone was menaquinone-7 and the major polar lipid was phosphatidylethanolamine. The genomic DNA G+C content of strain SW112T was 39 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain SW112T was related to members of the genus Belliella, showing the highest similarity with Belliella aquatica TS-T86Tand Belliella baltica DSM 15883T (96.5 % and 96.4 % sequence similarity, respectively). On the basis of phylogenetic inference and phenotypic characteristics, it is proposed that strain SW112T represents a novel species of the genus Belliella, for which the name Belliella marina sp. nov. is proposed. The type strain is SW112T ( = CGMCC 1.15180T = KCTC 33694T).

A non-motile and rod-shaped bacterium, designated strain WM78T, was isolated from freshwater collected from the Woopo wetland (Republic of Korea). Cells were Gram-stain-negative, aerobic, catalase-positive and oxidase-negative. The major fatty acids were iso-C15 :0, anteiso-C15 :0, C16 :1ω7c and/or C16 :1ω6c and iso-C17 :1 I and/or anteiso-C17 :1 B. The strain contained MK-7 as the major isoprenoid quinone, phosphatidylethanolamine as the major polar lipid and sym-homospermidine as the major polyamine. The genomic DNA G+C content was 62 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain WM78T forms evolutionary lineage within the radiation comprising members of the genus Hymenobacter with Hymenobacter gelipurpurascens Txg1T (97.7 % sequence similarity) as its nearest neighbour. A number of phenotypic characteristics distinguished strain WM78T from related members of the genus Hymenobacter. The evidence presented in this study support the designation of strain WM78T as a representative of a novel species in the genus Hymenobacter for which the name Hymenbactor wooponensis sp. nov. is proposed. The type strain is WM78T ( = KCTC 32528T = JCM 19491T).
