| 摘 要： | 采取油浓度梯度升高的方法,从胜利油田石油污染土壤中富集分离出以柴油为碳源和能源的优势除油混合菌B4。混合菌中分离出7株可培养菌。混合菌在含油0.5%的无机盐液体培养基中培养7天后柴油的去除率达到90.4%。该菌有较好的耐受性,当盐度达3.5时,油浓度达1.0%,亦有较好长势。混合菌对油污染土壤的修复有较好的效果,特别是加入营养盐,降解率达85.6%。混合菌脱氢酶动态变化的初步研究结果表明微生物活性变化与降解率有很好的相关性。

| Abstract: | A bacterial consortium consisting of seven members has been collected after enrichment from the oil polluted soil ofShengli Oil Field using diesel fuel as carbon and energy sources through the gradient rise method of the density of oil.The consortium degraded 90.4% of diesel fuel after incudating 7 days in liquid culture.The consortium has better tolerance,and grows better when the salinity is up to 3.5% and the density of oil is up to 1.0%.Better results are achieved in the bioremediation of the oil pollution soil using the consortium,especially when nutrition salt is added,the degradation rate being up to 85.6%.According to the preliminary study of the dynamic change of dehydrogenase,the bacterial dehydrogenase activity is highly correlated with the degradation rate. |
