硅酸盐结构对硅酸盐细菌生长代谢及脱硅的影响
Structural effects of silicate minerals on the growth, metabolism and desilicification of a strain of silicate bacterium
摘要
Abstract
Silicate mineral structures affect silicate bacterial grow th .A study is carried out on the grow th of a strain of silicate bacteria named JG-02 in the media containing kaolin ,quartz ,bauxite respectively by monitoring the physical and chemistry parameters ,surface changes of silicate minerals during bioleaching . The results show that the strain has the similar growth curves in different media ,but the number of bacteria , acid and polysaccharide production capacity vary greatly . The strain produces more acid , polysaccharide and maximum SiO2 (40 .8 mg/L) in kaolin medium .The quartz’s is less .However ,similar changes are shown on surfaces of kaolin and quartz by infrared ray .Therefore ,the growth of JG-02 and mineral erosion will happen more easily on the surfaces of layered silicate minerals than the frameworks .关键词
