Abstract: The composition of waste printed circuit boards (WPCBs) is complicated.WPCBs contain various non-ferrous and rare metals，and had the features of harm to environment and high potential value.In order to know about the research progress of recycling of WPCBs by microbiological method，and accelerate the technology development，metals leaching by chemoautotrophic bacteria and heterotrophic bacterium，bacterial adsorption was introducedIt is indicated that the future research direction proposed would focus on breeding of high efficient bacteria，the column leaching and the agitation leaching process，and a stirred tank reactor of the coarse-grained WPCBs，and so on.

Key words: Bacteria, Chemoautotrophic bacteria, Heterotrophic bacterium, WPCBs, Rcycling, Leaching, Adsorption
