摘要
研究了胶质芽孢杆菌对蛇纹石、橄榄石的风化释硅作用。方法:将5 ml细菌分别加入到100 ml含0.5 g蛇纹石和橄榄石矿粉的培养基中,对照组加等量的灭活菌,经不同的时间间隔测量样品释放硅的含量。结果表明,胶质芽孢杆菌对蛇纹石、橄榄石的风化释硅起着重要作用,而且随着时间的变化,释放的硅浓度变化表现出一定的规律性,即呈现出开始逐渐升高,到10 d左右达到最大值,然后有所降低但逐渐趋于稳定的趋势。同时发现蛇纹石和橄榄石被细菌作用后的表观形态有所不同。
This paper focuses on the silicon releasing from serpentine and olivine by Bacillus mucilaginous.The method used is that 5 ml bacteria culture are added to 100 ml medium with olivine and serpentine 0.5 g respectively,the equivalent of inactivated bacteria are added to the control group,then measuring the silicon content after different time intervals.The main results are presented as follows:Bacillus mucilaginous play an important role in the weathering of serpentine and olivine,and the concentration of Si ...
