摘要
利用4种真菌研究了硝酸氧化煤的微生物溶解作用.实验对细胞液、无细胞液和加煤诱导的无细胞液的溶煤效果进行了比较,细胞液的溶煤效果要优于无细胞培养液的溶煤效果,加煤诱导的无细胞液的溶煤效果要优于不加煤诱导的无细胞液;通过测定溶煤过程中的pH值的变化得出了溶煤碱溶机理;确定了菌种的生长时间为7d;煤的粒径越小越有利于微生物作用,溶煤效果越好.
Four fungal strains have been used for solubilizing oxidation lignite by nitric acid. In order to get some insight into the mechanism of biosolubilization,cell culture, cell-free culture filtrate and a coal induced cell-free culture filtrate were selected to study these solubilizing lignite results, cell culture of solubilizing result was superior to cell-free culture filtrate,a coal induced cell-free culture filtrate of solubilizing result was superior to a no coal induced cell-free culture filtrate; alkali mechanismof coal solubilizing have been attained through determining growth time and pH in process of solubilization; strain growth time is seven days; the granularity of coal is smaller , solubilization result is better.
