硫酸盐还原细菌生物被膜的形成与调控研究进展

Formation and regulation of sulfate-reducing bacteria biofilm: a review

摘要:

硫酸盐还原细菌(sulfate-reducing bacteria，SRB)形成的生物被膜是微生物导致金属锈蚀行为的主要原因，同时也是重金属污水微生物修复技术的关键因子。生物被膜形成及调控机制研究对SRB的防治和利用均十分重要。本文综述了近年来SRB生物被膜的研究进展，包括SRB生物被膜的胞外多聚物组成和控制因子，并着重阐述了目前已知的调控因子对SRB生物被膜形成的影响。

Abstract:

The biofilm of sulfate-reducing bacteria (SRB) is regarded as the main culprit of the microbially influenced corrosion, but it is also the key to the microbial remediation of heavy metal-polluted water. The formation and regulation mechanisms of biofilm are very important for SRB control and utilization. In this study, we summarized the research progresses on SRB biofilm, including extracellular components of biofilm and biofilm control factors, and elucidated the role of regulators in the biofilm formation.
