| 摘 要： | 嗜盐微生物能够在高盐环境中生存，其耐盐机制一直是微生物学家研究的热点。目前嗜盐微生物耐盐机制的研究主要集中在细胞吸K+排Na+作用、胞内积累小分子相容性溶质及嗜盐酶的氨基酸组成特性三个方面。文章从基因水平综述了嗜盐菌的耐盐机制，并对其在高盐废水处理上的应用进行讨论与展望。

| Abstract: | Halophilic microorganisms can thrive at hypersaline environments, and the mechanisms of salt-tolerance in halophilic microorganisms focused on the following three points: mechanisms of potassium-absorbing and sodium exclusion; accumulation of intracellular compatible solutes; the amino acid composition of halophilic enzyme. This paper reviewed the molecular mechanisms of salt-tolerance in halophilic bacteria and archaea, and discussed the prospects of the application in hypersaline wastewater treatment. |
