sp. nov., a red-pigmented bacterium from freshwater lake sediment, and proposal of as a latter heterotypic synonym of Free

Abstract

A taxonomic identification using a polyphasic approach was performed on strain NBS58-1, which was isolated from the interfacial sediment of Taihu Lake in China. Strain NBS58-1 was Gram-stain-negative, aerobic, non-spore-forming and catalase-positive. Phylogenetic analyses based on 16S rRNA gene and three housekeeping genes (, and ) sequences supported the position that strain NBS58-1 should be classified within the genus . The 16S rRNA gene sequence of strain NBS58-1 possessed the highest similarity to H-1 (96.60 %), followed by MDT1-10-3 (96.17 %). And the ANI value between strain NBS58-1 and MDT1-10-3 was 79.3 %. The respiratory quinone was menaquinone 7 (MK-7). The major cellular fatty acids comprised iso-C and summed feature 3. Phosphatidylethanolamine, two unidentified phospholipids and four unidentified lipids were the main polar lipids. The genomic DNA G+C content was 51.3 mol%. Based on phenotypic features and phylogenetic position, a novel species with the name sp. nov. is proposed. The type strain is NBS58-1=(KACC 21309=MCCC 1K04037). We also proposed as a latter heterotypic synonym of .
