| Abstract |
A Gram-negative, almost straight, rod-shaped, non-motile bacterium, designated CL-GP79(T), was isolated from a highly eutrophic pond located within the campus of Seoul National University, Korea. Phylogenetic analyses based on 16S rRNA gene sequencing showed that strain CL-GP79(T) belongs to the family Flexibacteraceae, with Flectobacillus major as its closest relative (similarity of 95.7 %). The cellular fatty acids consist mainly of C(16 : 1)omega5c (mean +/- sd, 26.9 +/- 10.8 %), iso-C(15 : 0) 2-OH and/or C(16 : 1)omega7c (19.2 +/- 2.3 %) and iso-C(15 : 0) (12.1 +/- 1.3 %). The DNA G + C content was found to be 38.3 mol%. Phenotypic, chemotaxonomic and phylogenetic analyses indicated that strain CL-GP79(T) could be assigned to the genus Flectobacillus, but could be distinguished from F. major. The strain CL-GP79(T) therefore represents a novel species, for which the name Flectobacillus lacus sp. nov. is proposed, with CL-GP79(T) (=KCCM 42271(T)=JCM 13398(T)) as the type strain.
