菌藻生物在成矿作用中的富金实验模拟

进行了菌落生物活体，死体，原油，有机质，有机淤泥和三种粘土矿物富金作用的对比实验，并研究了不同环境不同类型的菌藻生物在不同环境下的富金能力的差异，探讨了生物富金机理。结果表明活体菌藻生物富金能力比其他实验样品的强。与海水和淡水条件相比，温尔泉蓝细菌富金能力强；与常温条件相比，热水条件下的温泉蓝细菌富金能力强。

THE GOLD ENRICHMENT EXPERIMENTS OF BACTERIA AND ALGAE IN MINERALIZATION

The absorbing gold experiments of living bacteria and algae, dead ones, crude oil,organic matter, organic silt and three kinds of clay minerals are conducted. The difference of gold enriching ability of bacteria and algae in different environment is studied, and the mechanism of gold enrichment of organisms is discussed. The results show that the ability of enriching gold of living bacteria and algae is stronger than other samples and the cyanobacteria in hot spring is stronger than in others environments. In the oxidized environment of organisms living, the gold enrichment by organisms is expressed mainly as absorbtion, and the sulfure-bearing organic compound is the most important organism ligand playing a role in gold migration and concentration in cells.
