嗜盐古菌几种常见胞外酶研究进展

Extracellular enzymes of halophilic archaea:a review

嗜盐古菌是一类生活于极端高盐环境的化能异养型原核微生物,其所分泌的胞外酶(外泌酶)具有在高盐条件下仍能保持活性的特点,在制革工业、高盐有机废水处理和泡菜加工等腌制食品方面发挥重要用途。本文对嗜盐古菌的胞外蛋白酶、淀粉酶、酯酶等几种常见胞外酶的来源和基本酶学性质的最新研究进展进行综述,为更好地开发利用嗜盐古菌胞外酶资源提供参考。

Halophilic archaea is a kind of heterotrophic prokaryotes living in extremely high salinity environment.The extracellular enzymes secreted by these microorganisms can maintain enzymatic activity under the high salt condition,and play an important role in the leather industry,the treatment of high salt organic wastewater and pickle processing.In this paper,the sources and basic enzymatic properties of several common extracellular enzymes excreted by halophilic archaea such as extracellular protease,amylase and esterase are reviewed,to provide a reference for better exploitation and utilization of extracellular enzyme resources of halophilic archaea.
