Abstract
Moderate halophilic bacteria isolated from several kinds of salted and fermented sea foods (jeotkal) collected from commercial market were identified and investigated on their selt requirements. It was confirmed that the isolates were dominantly moderate halophiles according to their NaCl requirement to grow. And their salt requirements in their growth have been examined for Na, K, Ni and mg ions. Among them, the most dominant and distinctive three strains in protease pro-duction have been examined and two of them identified to be halophilic Flavobacterium sp., and the other one to be halophilic Pseudomonas sp..1'heir optimum growth was observed at 3
염장 식품인 젓갈류 15종류에서 호염성 세균을 분리하여 그들이 성장할 수 있는 NaCl 농도에 따라, 5-10% NaCl에서 잘 자라는 18균수와 10-20% NaCl 에서 더욱 잘 자라는 35균주를 구분하여, 이들을 moderate halophiles로 분류하였다. 분리한 moderate halophiles중에는 Flavobacterium-group I과 II 그러고 Pseudomonas sp.에 속하는 균주들이 있으며 이들은 3
