摘要
以含有不同矿物组成的含钾矿粉为材料，用硅酸盐细菌进行解钾试验。结果表明，每克含钾矿粉最多能释放７７．３μｇ水溶性钾，占矿粉全钾量的平均比率仅０．０５６％；经硅酸盐细菌分解后的含钾矿粉进行Ｘ－射线衍射分析，硅酸盐细菌对含钾矿物的晶体结构几乎没有产生破坏性作用，含钾矿粉所含主要矿物的相对含量变化不大，硅酸盐细菌表现不出明显的解钾效果。
Releasing potassium experiment was inducted by silicatebacteria on the different kinds of the potassiumbearing minerals powder. The minerals powder per gram could at most release 77.3 m of watersoluble potassium, and its potassium parcentage to the total mineral powder was only 0.056%; potassiumbearing mineral powder after being released by silicate bacteria were carried on the Xray diffraction analysis, the results indicated that silicate bacteria showed only a few influence on the crystal structure of silicate minerals; and the relative content of primary minerals in the potassiumbearing mineral powders had no obvious change.
