摘要:

旨在为共培养促进乳酸菌产细菌素的机制研究提供理论依据。乳酸菌细菌素是一种天然的食品防腐剂,能够有效抑制食品腐败菌和食源性致病菌的生长,因此受到了食品工业的广泛关注。目前已有研究表明,共培养能够增加乳酸菌细菌素的产量,群体感应在乳酸菌共培养产细菌素的过程中也发挥了重要作用。为了阐明共培养对乳酸菌产细菌素的促进作用,对乳酸菌细菌素的分类、生物合成机制以及群体感应系统对乳酸菌共培养产生细菌素的调控机制进行了总结,解析了三种因素对乳酸菌共培养的促进机制,阐明了群体感应对共培养条件下的细菌素产生具有重要的调节作用。

Abstract:

This paper aims to provide a theoretical basis for the study of the mechanism of co-culture to promote the production of bacteriocins by lactic acid bacteria. Lactobacillus bacteriocin is a natural food preservative, which can effectively inhibit the growth of food spoilage bacteria and food-borne pathogenic bacteria, so it has received extensive attention from the food industry. At present, studies have shown that co-culture can increase the production of bacteriocins of lactic acid bacteria, and quorum sensing also plays an important role in the process of co-culturing bacteriocins of lactic acid bacteria. In order to clarify the promotion effect of co-culture on the production of bacteriocins by lactic acid bacteria, this paper summarizes the classification of lactic acid bacteria bacteriocins, the biosynthetic mechanism, and the regulation mechanism of quorum sensing system on the production of bacteriocins by lactic acid bacteria co-culture, and analyzes the effects of the above three factors on the co-culture of lactic acid bacteria. The promotion mechanism of culture clarifies that quorum sensing plays an important role in regulating bacteriocin production under co-culture conditions.

Key words: co-culture, lactic acid bacteria, bacteriocin, mechanism of action, quorum sensing
