| The Paper studied the releasing potassium from two kind of insoluble potassium -bearing minerals by fermentting
feldspathic mineral and glauoonite with silicate bacteria strains Z1, Z9, S5, and analyzed the potassium ion dynamic process among the components “liquidoid-bacteria- mineral冶of mineral fermentation. Results revealed that all strains had ability of releasing potassium from insoluble potassium-bearing minerals, strain Z9, S5 got the optimal effect on feldspathic mineral and glauoonite's dissolution respectively, and all strains had no obvious specificity on both minerals. The potassium releasing rate of glauoonite fermentation was higher than feldspathic mineral fermentation. The diversity results of fermentation effect was determined by potassium ion concentration in “liquidoid” of fermentation medium. |
