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

School of Earth and Environmental Sciences and Research Institute of Oceanography, Seoul National University, Shillim-dong, Kwanak-gu, Seoul 151-742, Republic of Korea Correspondence Byung Cheol Cho bccho{at}snu.ac.kr 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 °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 7 c (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. The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain CL-GP80 T is DQ112353 . Details of the cellular fatty acid compositions of strain CL-GP80 T and other Pedobacter species are available as supplementary material in IJSEM Online.
