中文摘要:
      以Z1、Z9、S5等3株硅酸盐细菌菌株为研究对象,对含钾岩石和海绿石两种不溶性含钾矿物进行发酵解矿,对其解矿释钾能力及发酵过程“菌-液-矿”各组分解钾动态过程进行研究。结果表明,3株硅酸盐细菌均有一定程度的解矿能力,解含钾岩石最优的为Z9菌株,解海绿石最优的为S5菌株,3株菌对2种供试矿的种类没有明显特异性。海绿石解钾率普遍高于含钾岩石解钾率,发酵过程速效钾浓度的差异主要由发酵液液相组分所含的速效钾决定。
英文摘要:
      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.
