Novosphingobium taihuense sp. nov., a novel aromatic-compound-degrading bacterium isolated from Taihu Lake, China

An aerobic, yellow-pigmented, Gram-negative bacterium, designated strain S13 T , was isolated from freshwater sediment of Taihu Lake in central China. The taxonomy of strain S13 T was studied by using phenotypic and phylogenetic methods. Cells of strain S13 T were rod-shaped, non-motile and with a size range of 0?35-0?5561?5-2?5 mm. The nearly complete 16S rRNA gene of strain S13 T was amplified and sequenced. A BLAST search and phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain S13 T was related to members of the genus Flavobacterium, with the highest sequence similarity of 93?8 % to Flavobacterium columnare (ATCC 23463 T ). Cells contained menaquinone-6 (MK-6) as the major respiratory quinone and the genomic DNA G+C content was 41 mol%. The major fatty acids were iso-C 15 : 0 (28?2 %) and iso-C 17 : 1 v9c (19?0 %). It is proposed that S13 T (=CGMCC 1.3801 T =JCM 13331 T ) represents the type strain of a novel species, Flavobacterium saliperosum sp. nov.
