Abstract
In this study, samples were collected from the Sumummulbangdui wetland at the Halla Mountain in Jeju Island in order to isolate novel bacterial strain. Bacterial strains belonging to the class Alphaproteobacteria, and Gammaproteobacteria were isolated after spreading samples onto solid agar media. The 16S rRNA gene sequences of the strains assigned to the two classes were compared to those of type strains of the species. The strains that showed less than 98.7% 16S rRNA gene sequence similarity to the validly published species were considered to be novel species candidates. A total of 19 strains were regarded as novel strains which can be regarded as novel species candidates. In the Alphaproteobacteria, 6 novel strains were affiliated with the genera Novosphingobium, and Rhizobium. A total of 13 novel strains belong to Gammaproteobacteria that assigned to the family Moraxellaceae, Pseudomonadaceae, and Enterobacteriaceae were identified. Cultural, physiological, chemotaxonomic characteristics and fatty acids compositions have been determined for the novel species candidates, and the characteristics are described in this study.
