微生物诱导下甲烷厌氧氧化及碳酸盐矿物生成实验
Experiment on anaerobic oxidation of methane and precipitation of carbonate mediated by microbes
摘要
Abstract
Themethane oxidizing bacteriawasisolated from lake bottom sediment andthecorresponding DNA sequencingwascarriedout. Experimentofinteraction between methane oxidizing bacteria-water-rock was conducted in a self-developed reactor system,andvariations of the number of microorganismsand themassconcentration of HCO3−were analyzed, respectively. Finally, rock sliceswereviewedwithscanning electron microscope(SEM).The results show that the cultured methane oxidizing bacteria belongsto pseudomonas genus. HCO3−produced after bacteria injected into the reactor. Changes ofmassconcentration of HCO3−have certain correlation relationship with the number and microbial activity of microorganism. Intermediateminerals, including amorphous ankerite, bright columnar of carbonate and feldspars, are precipitated on the surface of quartz sandstone.关键词
