For further understanding the effect of the strain on K-bearing silicate mineral, an experiment with KO2 strain cultured in nitrogen-containing and nitrogen-free medium was conducted. By putting mineral powders into the medium and measuring the concentration of capsular polysaccharides, we concluded that the strain can accelerate the weathering rate of silicate minerals. The results showed that the polysaccharides secreted by the strain in the growth process could help the bacterial to adhere to the mineral surface effectively, and created the bacterium-mineral complex, which formed a mircro-enviorment avail the release of potassium. Another result was that there was higher level of Carbonic Anhydrase activity, which revealed that some exo-protein or enzyme produced by the bacterial had postive impact on the process of releasing potassium ion. We carried out the bacterial fermentation for larger scale production of the bacterial secretion, which was used to sperate, and identify the small molecules related to the mineral-bacterial interaction. After the analysis, it was found that the strain can produce many kinds of small molecules, such as 2-Hydroxybenzoic acid, 4-Hydroxyphenylacetic acid, methyl-4-hydroxybenzoate, etc.
