Pedobacter roseus sp nov., isolated from a hypertrophic pond, and emended description of the genus Pedobacter

A Gram-negative, pink-coloured, rod-shaped, non-flagellated bacterium, designated CL-Gp80(T), was isolated from a hypertrophic pond located within the campus of Seoul National University, Korea. Analysis of its 16S rRNA gene sequence revealed that strain CL-GP80(T) belongs to the family Sphingobacteriaceae and is closely related to Pedobacter heparinus ATCC 13125(T) (95(.)8% sequence similarity) and to other members of the genus Pedobacter (90(.)8-95(.)3 % similarity). Temperature and pH ranges for growth were 5-33 degrees C and pH 6-8, respectively. The DNA G + C content was 41(.)3 mol%. The major fatty acids were iso-C-15:0 (37-0 %), iSO-C-15:0 2-OH and/or C-16:1 omega 7c (24(.)5 %), and iso-C-17:0 3-OH (11(.)3 %). Phenotypic, chemotaxonomic and phylogenetic analyses indicated that strain CL-Gp80(T) could be assigned to the genus Pedobacter, but distinguished from recognized species of the genus. Strain CL-GP80(T) (= KCCM 42272(T)=JCM 13399(T)) is therefore proposed as the type strain of a novel species, for which the name Pedobacter roseus sp. nov. is proposed.
