Kaistia adipata gen. nov., sp. nov., a novel α-proteobacterium

[摘要] A taxonomic study was carried out on Chj404T †, a bacterial strain isolated from a soil sample collected in an industrial stream near the Chung-Ju industrial complex in Korea. The strain was a gram-negative, aerobic, short rod to coccus-shaped bacterium. It grew well on nutrient agar medium and utilized a broad spectrum of carbon sources. The G+C content of the DNA was 67.4 mol% and the major composition of ubiquinone was Q-10. The major fatty acid was C18:1. Comparative 16S rDNA studies showed a clear affiliation of this bacterium to α-Proteobacteria. Comparison of phylogenetic data indicated that it was most closely related to Prosthecomicrobium pneumaticum (92.7% similarity in 16S rDNA sequence). Since strain Chj404 is clearly distinct from closely related species, we propose the name Kaistia adipata gen. nov., sp. nov. for this strain Chj404T (=IAM 15023T=KCTC 12095T).
