摘要: 将分离得到的一株胶质芽孢杆菌RGBc13接种到砂土和以不同的硅酸盐为唯一钾源的培养基中,并进行培养,发现这株细菌具有明显的解钾和解磷作用,使砂土中磷、钾和硅的含量大幅度提高,硅酸盐矿物中的钾释放出来,改变为可提取的形态,但对不同的硅酸盐矿物,该株细菌的分解能力差异很大。释放出来的钾一部分被微生物吸收,熏蒸处理能够使这部分钾从细胞中释放出来。

Abstract: One strain of B. Mucilaginosus was inoculated into sandy soil and the media containing different silicate minerals. It was found that phosphorus, potassium and silicon content increased significantly in the sandy soil. Potassium was released at different rates from 5 different silicate minerals and became extractable. A small amount of the potassium released from the minerals was absorbed by bacterium. Fumigation could make the K inside the cell extractable to water.
