| 摘 要： | 利用硅酸盐细菌研究了微生物对硅酸盐矿物的分解作用。选取层状硅酸盐矿物蒙脱石在30℃与一株编号为3025的硅酸盐细菌B.mucilaginosus进行交互作用,并利用电感耦合等离子体发射光谱仪(ICP-AES)分析溶液中Si、Al、Mg离子的出溶量,利用X射线衍射(XRD)和显微红外光谱(Micro-FTIR)分析微生物作用后矿物物相和微结构变化。发现经硅酸盐细菌作用后,蒙脱石化学成分及晶体结构发生了细微变化,为微生物活动促进粘土矿物分解作用研究提供了实验和理论依据。

| Abstract: | The impact of microbes on lithosphere starts with the change of minerals comprising rocks,whereas the impact of microbes on minerals starts with the change of the composition of minerals.Based on previous researches on the interaction between microbes and minerals,this paper studied the interaction between silicate bacteria Bacillus mucilaginosus and bentonite,which is mainly composed of layer silicate montmorillonite and a small amount of other silicate minerals such as quartz and feldspar,and analyzed the... |
