Abstract
Silicate bacteria generally placed in the species Bacillus circulans and Bacillus mucilaginosus and Bacillus edaphics can liberated silicon from ores. Silicate bacteria from different resources have an obvious different abilities of desilicon. A single bioleaching and cooperative bioleaching(Bacillus circulans and Bacillus mucilaginosus and Bacillus edaphics) was investigated by measurements of the leaching rate of silicon from bauxite. Results shows that the leaching rate of silicon with a mixed incubation of the tested three strains in accordance with the ratio of 2: 2: 1 is much higher than that of them respective, and also obviously higher than that of other forms of mixed culture by the three strains.
