10.Based on the research on the physical and biochemical characteristics of bacteria A and its influencing elements of environment, we takes advantages of enzyme digestion process happening in the growth of carbonate-mineralization microbe----bacteria A, and adds Ca 2+ properly, thus orbicular CaCO3 whose diameter is less than 10μm is precipitated successfully, which is proved to be calcite crystalloid through XRD analysis.
在研究菌株A的生理生化特性与环境影响因素的基础上,本研究利用碳酸盐矿化菌——菌株A生长繁殖过程中产生的酶化作用,适时引入Ca2+,24h内顺利沉积出直径小于10μm的球形CaCO3,经XRD分析证实为方解石晶型。
