Bioremediation of soil contaminated crude oil by Agaricomycetes
BACKGROUND One of the most important environmental problems is the decontamination of petroleum hydrocarbons polluted soil, particularly in the oil-rich country. Bioremediation is the most effective way to remove these pollutants in the soil. Spent mushroom compost has great ability to decompose lignin-like pollution. The purpose of this study was the bioremediation of soil contaminated with cr...
متن کاملBioremediation of Soil Contaminated by Diesel Oil
Were evaluated natural attenuation, biostimulation and bioaugmentation on the degradation of total petroleum hydrocarbons (TPH) in soils contaminated with diesel oil. Bioaugmentation showed the greatest degradation in the light (C12 C23) fractions (72.7%) and heavy (C23 C40) fractions of TPH (75.2%) and natural attenuation was more effective than biostimulation. The greatest dehydrogenase activ...
متن کاملBioremediation of Heavy Crude Oil Contamination
Crude oil contamination is one of the major environmental concerns and it has drawn interest from researchers and industries. Heavy oils contain 24-64% saturates and aromatics, 14-39% resins and 11-45% asphaltene. Resins and asphaltenes mainly consist of naphthenic aromatic hydrocarbons with alicyclic chains which are the hardest to degrade. Crude oil biodegradation process, with its minimal en...
متن کاملBioremediation of Crude Oil Contaminated Soil by Petroleum-Degrading Active Bacteria
Approximatelly 0.6 million tons of petroleum is poured into soil, groundwater, rivers and oceans every year in China. A large amount of the oil contaminated soil has not been remediated. The contaminated soil poses a severe threat to the environment and must be taken care of. Bioremediation has become one of the most popular and promising technologies with growing demand for the remediation of ...
متن کاملBioremediation of petroleum hydrocarbons from crude oil-contaminated soil with the earthworm: Hyperiodrilus africanus
A study on the bioremediation potentials of the earthworm Hyperiodrilus africanus (Beddard) in soil contaminated with crude oil was investigated. Dried and sieved soils were contaminated with 5 ml each of crude oil with replicates and inoculated with earthworms and monitored daily for 12 weeks. Physicochemical parameters such as pH, total organic carbon, sulfate, nitrate, phosphate, sodium, pot...
