摘　　要：生物冶金体系中,微生物生物膜发挥重要作用。综述了浸出体系中生物膜组成及生物膜形成对矿物浸出的作用,以及生物膜的复杂调控机制,指出从基因组学、转录组学、蛋白质组学等方面研究生物膜的形成与调控机制,对有效消除浸矿过程中钝化膜的形成、提高细菌浸出速率、提高金属回收率有重要意义。Microbial biofilm plays an important role in bioleaching system. The effect of biofilm and biofilm composition on metal sulfides and complex regulatory mechanism of biofilm were summarized. It points out that formation and regulatory mechanism of biofilm can be researched from genomics, transcriptomics,proteomics,and so on. The research results are very important for eliminating passive film formatting during leaching of minerals and increasing bacteria leaching rate and metals recovery.
