초록
During a comprehensive investigation of indigenous prokaryotic species in Korea, a total 31 bacterial strains assigned to the class Alphaproteobacteria were isolated from diverse environmental habitats including freshwater, seawater, brackish water, ginseng soil, plant roots, natural caves, and tidal flats. Based on their high 16S rRNA gene sequence similarities (>99.1%) and formation of robust phylogenetic clades with the closest type species, each strain was assigned to an independent and predefined bacterial species. Because there were no published or official reports regarding the isolation of these 31 species in Korea, this study identified three species in two genera in the order Caulobacterales, 12 species in 10 genera in the order Rhodobacterales, three species in two genera in the order Rhizobiales, two species in two genera in the order Rhodospirillales and 11 species in seven genera, all in the order Sphingomonadaceae within the Alphaproteobacteria are reported as new alphaproteobacterial species in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are described in the species description section.
Abstract
During a comprehensive investigation of indigenous prokaryotic species in Korea, a total 31 bacterial strains assigned to the class Alphaproteobacteria were isolated from diverse environmental habitats including freshwater, seawater, brackish water, ginseng soil, plant roots, natural caves, and tidal flats.
