摘要
应用胶质芽孢杆菌(Bacillus mucilaginosus)作分解土壤矿物试验。从土壤矿物经该菌处理前后的表面光滑程度、表面积以及上清液中K、Si离子浓度的变化等方面证明了胶质芽孢杆菌能够分解土壤矿物,并把其中的K、Si从矿物晶格中释放出来。同时还表明胶质芽孢杆菌NS01分解矿物与其生长过程中产生的荚膜多糖与小分子有机酸的复合作用有关。
The role and mechanisms of Bacillus mucilaginosus in extracting K+ and SiO2 from silicate soil were studied. It was found that B. mucilaginosus can dissolve soil minerals and release K+ and SiO2 from crystal lattices of the minerals. At the same time the results also showed that there is a correlation between the capability of the bacterium of dissolving minerals and its capsular polysaccharides and the complexing action of small molecular organic acids.
