dc.description.abstractMarine psychrophilic bacteria that inhabit seawater at below 4C, play essential roles in marine ecosystem. To investigate their distribution in the Antarctic region, we have isolated 35 strains of polar bacteria originated from Antarctic sea water, fresh water in the vicinity of the King Sejong Korean Antarctic Station located at King George Island (62S, 58W) during November and December, 2005. To examine their growing temperature ranges, we measured average diameter of colonies formed at various temperature ranging from 4C to 37C. Among them, 10 strains have formed large colonies at low temperatures and shown the highest growth rate at 4C or 15C, and formed no colony above 20C. We have carried out molecular identification using 16S rRNA sequence as a marker. As a result, 8 strains were identified as belonging to genus Flavobacterium, 12 strains to genus Psychrobacter species like P. arcticus, P. glacincola, and P. luti. Also, nine Antarctic strains showing low sewuence similarity (<97%) with known species are candidates for new species or genus. In this study, we isolated 35 psychrophilic or psychrotolerant bacteria from Antarctic region and they would be useful biological sources for studying cold adaptation of living organisms.-
