乳酸菌降解亚硝酸盐和反硝化细菌亚硝酸盐还原酶结构研究进展

Research Progress on the Structure of Nitrite Reductase of Denitrifying Bacteria and Degradation of Nitrite by Lactic Acid Bacteria

亚硝酸盐具有发色、杀菌、抗氧化、增强风味等功能,是常见的食品添加剂。亚硝酸盐使用不当会引起食品安全问题,严重影响消费者的健康。因此,高效降低亚硝酸盐残留,解除亚硝酸盐威胁,从而保证食品安全显得越发重要。文章综述了近年来乳酸菌降解亚硝酸盐、反硝化细菌在极端条件下降解亚硝酸盐以及反硝化细菌亚硝酸盐还原酶结构特点相关研究。

Nitrite is a common food additive,which has the functions of color forming,sterilization,oxidation resistance and flavor enhancement.Improper use of nitrite will cause food safety problems and seriously affect the health of consumers.Therefore,it is more and more important to effectively reduce nitrite residue and eliminate the threat of nitrite to ensure food safety.In this paper,recent studies on the degradation of nitrite by lactic acid bacteria,the degradation of nitrite by denitrifying bacteria under extreme conditions and the structure of nitrite reductase of denitrifying bacteria are reviewed.
