Remediation of metal-contaminated soil and sludge using biosurfactant technology.
Development of environmentally benign approaches to remediation of metal-contaminated soils and sewage sludges are needed to replace currently used techniques of either landfilling or metal extraction using caustic or toxic agents. We report results from four application technologies that use a metal-chelating biosurfactant, rhamnolipid, for removal of metals or metal-associated toxicity from m...
متن کاملbioremediation of pyrene-contaminated soils using biosurfactant
conclusions application of rhamnolipid biosurfactant produced by pseudomonas aeruginosa significantly improved pyrene removal in contaminated soils. results the pyrene removal efficiency in samples containing biosurfactant, without biosurfactant and controls, were 86.4%, 59.8% and 14%, respectively, after 63 days. the difference of pyrene removal efficiency between the biosurfactant-containing ...
متن کاملBiosurfactant-facilitated remediation of metal-contaminated soils.
Bioremediation of metal-contaminated wastestreams has been successfully demonstrated. Normally, whole cells or microbial exopolymers are used to concentrate and/or precipitate metals in the wastestream to aid in metal removal. Analogous remediation of metal-contaminated soils is more complex because microbial cells or large exopolymers do not move freely through the soil. The use of microbially...
متن کاملAnaerobic bioremediation approach to remove TPH contaminated soil
Total petroleum hydrocarbon (TPH) is a complex mixture of hydrocarbons including saturate fraction such as n-alkanes, branched alkanes, and cycloalkanes (naphthenes). TPH is normally come from the accidental leakage of storage tanks of lubricating and fuel oils resulting in the soil contamination. TPH is classified as the hazardous material and is considered as the most organic pollutants in th...
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...
