- 摘要:从松藻煤矿分离到的氧化亚铁硫杆菌(Thiobacillus ferrooxidans)菌株T-4,能够利用煤炭中的黄铁矿作为能源基质,用含有细胞量108-109个/ml,pH1.55-1.70的种菌液,脱除煤炭中的无机硫,并进行了细菌煤炭脱硫的条件试验,9个样品4—72h试验结果,总硫量由1.31—2.45%降至1.05—1.88%,黄铁矿硫脱除率达86.11—95.16%.
- Abstract:A culture of Thiobacillus ferrooxidans strain T-4 isolated from Song Zao Mine (China) was found to be able to use the pyrite in coal as a source of energy. The bacterial culture solution with concentration of 108-109 cell/ml, pH of 1.55-1.70 was used for removal of pyritic sulfur at an initial condition of pH 1.60-1.79, 30℃, 20-30%coal pulp density. The total sulfur reduced ranged from 1.31-2.45% to 1.05-1.88% during 472 hours.
