乳酸菌对重金属吸附作用的研究进展

Research progress in the adsorption of heavy metals by lactic acid bacteria

摘要:

重金属污染是人们关注的食品安全问题热点之一，使用食品安全级乳酸菌吸附重金属成为了新的研究方向。本文在分析环境和食品中汞、镉、铅污染的来源及对人类危害的基础上，对微生物与重金属的相互作用进行介绍，重点归纳了乳酸菌作为重金属吸附剂的潜能，以及吸附重金属的作用机制和研究现状，为研发高效吸附重金属的乳酸菌吸附剂提供了可行性的思路。

Abstract:

Heavy metals pollution is one of the hot issues in food safety. The use of food grade lactic acid bacteria to adsorb heavy metals has become a new research area. In this review article, we introduce the sources and harms of mercury, cadmium, and lead pollutions in the environment and food. We also summarize the potential application and mechanisms of adsorbing heavy metals using lactic acid bacteria. This review provided a feasible way to develop efficient adsorbent for lactic acid bacteria adsorbing heavy metals.
