摘要: 乳酸菌作为发酵工业的常用菌种已被广泛用于制作各种发酵食品,且可以调节肠道菌群,对人体健康起着关键作用,因此,乳酸菌功能的应用成为当前研究的热点。乳酸菌生物膜由菌体自身形成,可以有效提高乳酸菌的环境耐受性,因而受到越来越多的学者关注。在众多影响生物膜形成的因素中,金属离子影响效果显著。本文主要对国内外关于金属离子对于乳酸菌生物膜形成的影响及其机制进行论述,旨在为阐明金属离子和乳酸菌生物膜形成机制的关系提供一定的理论参考和研究方向。

Abstract: Lactic acid bacteria have been widely used in various fermented foods, and their existence in human physiological flora plays a key role in human health. Therefore, the application of lactic acid bacteria has become a current research hotspot. The biofilm forming ability of lactic acid bacteria has attracted growing attention of researchers because the biofilm can effectively improve the environmental tolerance of lactic acid bacteria. Studies have shown that metal ions have a significant effect on the formation of biofilms among the various factors. This review paper discusses the influence and mechanism of metal ions on the biofilm formation of lactic acid bacteria, with the aim to provide a theoretical basis and future direction for clarifying the relationship between metal ions and the biofilm formation mechanism of lactic acid bacteria.

Key words: lactic acid bacteria, biofilm, tolerance, metal ions, effect mechanism
