中度嗜盐菌在生物技术中的应用

Biotechnology Applications in Moderately Halophilic Eubacteria

摘要:

生存于盐环境下的中度嗜盐菌在生物技术方面具有很多潜在的应用价值。其中，中度嗜盐菌在盐发酵食品加工业和食品添加剂中已经被广泛应用；由中度嗜盐菌分泌的胞外酶如淀粉酶、脂肪酶等能够在高盐环境下继续保持较高的活力；中度嗜盐菌细胞内积累的多种类相容性溶质也可以作为生物大分子稳定剂以及抗冻剂等；其它如其产生的生物表面活性剂、多聚糖类物质能够在石油回收和生物修复中进行应用等。

Abstract:

Moderately halophilic eubacteria that able to live in saline environments offer a multitude of potential applications in various fields of biotechnology.The technical applications of food industry comprise fermented foods and food additive.Enzymes，such as amylase and lipase，are of activity in high salt environments for commercial purposes.Compatibles solutes are useful as stabilizers of biomacromolecule and salt antagonists.Other useful such as biosurfactants and exopolysaccharides，are interest for microbial enhanced oil recovery and bioremediation and so on.
