摘要
嗜冷菌是指生活在低温环境下且其最高生长温度不超过20℃,最适宜温度在15℃,在0℃可生长繁殖的微生物.低温微生物具有细胞质膜的流动性、低温酶、蛋白质合成及冷休克蛋白等独特的分子结构、代谢机制和生理生化特征来适应寒冷气候,并在污水处理中得以应用.
Psychrophiles is a microorganism to under the low temperature environment point to live and its tallest growth temperature not over 20 ℃,the most suitable and proper temperature at 15 ℃,growing to breed at 0 ℃.They have construction and function mechanisms of its oneself to the cold and environmental orientation.This text overview is the Psychrophiles in cold germ mechanism,and introduce the main use of the cold germ in the text tail.
