Abstract

A total of forty strains of pigment-producing halophilic bacteria were isolated from the solar saltern and coastal seawater in Korea. The diversity of those bacteria were determined on the basis of PCR-RFLP and 16S rDNA sequences. The isolated strains were clssified into nine genera: Pseudoalteromonas, Photobacterium, Vibrio, Halobacillus, Bacillus, Paracoccus, Salinicoccus, Tenacilbaculum, and Flavobacterium. While more than $80\%$ of the pigment-producing halophilic bacteria isolated from the coastal seawater were classified as gram-negative Pseudolateromonas, most of the strains isolated from the solar saltern were classified into gram-positive Halo­bacillus. The other strain was KK7, which may be identified as novel species belonging to the genus, Salini­coccus.

한국 근해와 염전으로부터 40 균주의 색소 생성 호염세균을 분리하여, 16S rDNA PCR-RELP와 16S rDNA 염기서열 분석을 통하여 다양성을 파악하였다. 분리된 호염성 색소 생성 세균들은 Pseudoalteromonas, Photobacterium, Vibrio, Halobavillus, Bacillus, Paracoccus, Salinicoccus, Tenacibaculum, Flavobacterium의 다양한 속의 세균 종이었다. 해양에서 분리한 색소생성 호염 세균의 $80\%$ 이상이 그람음성인 Pseudoalteromonas 속이었으며, 염전에서 분리한 세균의 대부분은 그람양성의 Halobavillus속 세균이었다. 또한 Salinicoccus 속에 속하는 신종 가능성이 있는 균주 KK7을 분리하였다.
