The bioremediation of the heavy oil is often limited by high viscosity and low bioavailability. The aim of the present study was to find methods for enhancing rates of heavy oil biodegradation. Biodegradation of heavy oil by mixed bacterial consortium (BC) amended with Glycolipid biosurfactant (GBS) was monitored in shake flask conditions, which showed a significant reduction of the heavy oil at two...
Restoration of petroleum-contaminated soil is one of the most important issues of environment protection all over the world. In order to study the influence of pollution concentration on biodegradation, a specific exogenous microbe, Phanerochaete chrysosporium, was employed for bioremediation of soil contaminated by different concentrations of petroleum. After 60d of treatment, the degradation rate...
Oil-degrading strains were domesticated and enriched using the medium recycling method. Then the microorganisms were used in bioremediation of oil-contaminated soil from Daqing Oilfield, China. The laboratory study showed that the addition of enhanced microorganism and medium can make the oil degrading efficiency reach to more than 90% after 150 days degradation. The activity of the predominant microorganism...
With the rapid development of the petroleum industry, a large number of oil contaminants leaked into the soil in the petrochemical complex areas, gas stations, automobile factory and other places, which resulted in serious soil and groundwater contamination. Micro-biological degradation of oil pollution is the focus of the present study, while the mechanism of mutual promotion and restriction of restoration...
