Abstract

Phylogenetic analysis of two cellulase genes, xynB1 and bglA2, and the groEL1 gene from 34 Sorangium cellulosum strains isolated in Korea suggested that there are at least five subgroups in S. cellulosum, which is the most proficient producer of secondary metabolites among myxobacteria. This analysis also revealed diversity among the isolated S. cellulosum. It appeared that at least 30 out of 34 strains are different each other.

두 개의 cellulase 유전자 xynB1, bglA2과 groEL1 유전자 염기서열에 기초하여 국내에서 분리한 34균주의 Sorangium cellulosum 균주들을 계통 분석한 결과, 점액세균 중 가장 많은 생리활성물질이 발견된 종인 S. cellulosum 내에는 최소한 5그룹의 소그룹이 존재함을 보였다. 이 분석은 또한 S. cellulosum 균주들의 다양성을 보여주어 분석한 34균주 중 30균주가 서로 다른 균주인 것으로 나타났다.
