곰소 염전 퇴적물에서의 체외효소 활성도 = Extracellular enzyme activities in the solar saltern sediments

다국어 초록 (Multilingual Abstract)

Extracellular enzymes produced by microbes in hypersaline environments have been reported to possess a wide range of biocatalytic activities capable of functioning under the prevailing extreme conditions. To facilitate the industrial application of microbial enzymes sourced from extreme environments, we investigated the physiochemical properties and extracellular enzyme activities in solar saltern sediments. Our results indicate that high salinity induces an increase in the levels of dissolved organic carbon (DOC), which enhances the activities of cellulase, chitinase, and sulfatase by increasing the energy supplied to microbes. Therefore, enzymes and microbes that can be potentially used in future industrial applications was found in solar saltern.

국문 초록 (Abstract)

고염분 환경에 서식하는 미생물들은 극한 환경에서도 유기물을 분해하기 위하여 다양한 형태의 체외효소를 만들어낸다.
특히 극한 환경에서 만들어진 효소들은 산업적으로 이용 가능성이 높기 때문에, 고염분 환경인 염전의 퇴적물에서 발생되는 체외효소 활성도를 측정하였다. 그 결과, 유기용존탄소의양과 염분 농도간의 강한 상관관계가 나타났으며, 미생물에 대한 용존유기탄소의 공급 증가는 Cellulase, Chitinase, Sulfatase 의 활성도를 증가시켰다. 따라서 향후 산업적 가치를 고려하였을 때, 고염분의 환경인 염전에서의 체외효소활성도에 대한이용과 연구가 필요할 것으로 판단된다.
