乳酸菌对重金属污染的生物修复作用

Bioremediation of heavy metal contamination by Lactic acid bacteria

乳酸菌具有吸附及积累重金属离子的特性,且乳酸菌对重金属污染的生物修复作用的安全性较高。本研究综述了乳酸菌修复重金属污染的机制,及乳酸菌生物修复重金属污染水体、农产品及生物体的研究现状,为重金属污染的修复提供新思路。乳酸菌作为自然环境中普遍存在的一种安全且可食用微生物,其在生物修复重金属污染方面将发挥其独有的优势。

Lactic acid bacteria are capable of adsorption and accumulation of various heavy metals. The bioremediation of heavy metal pollution by lactic acid bacteria possesses high security. This review summarized the mechanism of bioremediation of heavy metal contamination by lactic acid bacteria,and the current research situation of lactic acid bacteria bioremediation for heavy metal pollution,such as the pollution of water,agricultural products and organisms,with purpose of providing new ideas for restoration of heavy metal pollution. Since lactic acid bacteria is a kind of safe and edible microbe in natural environment,it will play its unique advantageous role in the bioremediation of heavy metal pollution.
