ABSTRACT
A Gram-stain negative, aerobic, non-flagellated, rod-shaped bacterium, designated strain SM1810T, was isolated from deep-sea sediment collected from the Southwest Indian Ocean. Strain SM1810T grows at 15-40 °C (optimum, 28 °C), at pH 5.0-9.0 (optimum, pH 6.0-7.0) and with 0-8% (w/v) NaCl (optimum, 1.5%). Phylogenetic analysis of 16S rRNA gene sequences revealed that strain SM1810T is affiliated with the genus Pedobacter, sharing high sequence similarity (95.8%) with the type strain of Pedobacter bauzanensis. The major fatty acids of strain SM1810T are iso-C150, summed feature 3 (C161ω7c and/or C161ω6c) and iso-C170 3OH. The predominant respiratory quinone is MK-7. The polar lipids are phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified phospholipid and eight unidentified lipids. The genomic DNA G + C content of strain SM1810T was determined to be 40.8 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data obtained in this study, strain SM1810T is concluded to represent a novel species of the genus Pedobacter, for which the name Pedobacter indicus sp. nov. is proposed. The type strain is SM1810T (KCTC 62798T = CCTCC AB 2018198T).
