摘要
Microorganisms in the lateritic profiles of the Lianxian gold deposit in Guangdong were cultured, isolated and identified. The microorganisms include bacteria such as Bacillus, Enterobacter, Pseudomonas, Lactobacillus, Actinetobacter, Aeromona, Listeria, Agrobacterium, Corynebacterium, and Moraxella, fungi such as Penicillium, Alternaria, Cladosporium, Saccharcomyces, Mucor, and the chemoautotrophic Thiobacillus. It is shown in a leaching experiment that the microorganisms can accelerate the leaching of Cu, Cd, Zn, and that the G+- bacteria are most efficient for leaching Cu, Zn and the G++ bacteria are better for leaching Cd.
