Physiological And Biochemical

Ten strains of silicate bacteria were screened from three bauxite samples in Jiangxi Province and Henan Province in China. The ten strains were determined as B. mucilaginosus according to the results of physiological and biochemical characteristics and desilicon ability. Bioleaching tests showed that the ten strains all can decompose bauxite ore and release silicon from bauxite, but had a large difference of desilicon ability among them.

The strain Jgj-1 was isolated from Gaoan bauxite ore. The relations of desilication of the strain Jgj-1 and the pH of solution, temperature, shaking speed, incubation time, particle size were investigated. The results shows the optimum conditions of bioleaching are as following: at 28°C, initial pH value is 7.2, particle size 0.056mm, 200rpm shaking speed, incubation 5-7 days.

Adsorption Amount

The effects of biosorption time and cell concentration on adsorption amount on the surface of diaspore, kaolinite and quartz were studied by using two kinds of silicate bacteria ____Bacillus circulans and Bacillus mucilaginosus, and three kinds of silicate minerals . the experimental results show that two kinds of silicate bacteria absorb more easily on the surface of diaspore than on that of kaolinite and quartz, and the adsorption amount of the strain of B•M is always higher than that of the strain of B•C on the surface of diaspore, kaolinite and quartz .The possible reason is that the pHPZC of diaspore is higher than that of kaolinite and quartz, and the strain of B•M probably produce more metabolites charged negatively than that of B•C in incubation process.
