Top Companies. Bioremediation, the use of microbial degradation processes to detoxify environmental contamination, was first applied to petroleum hydrocarbon-contaminated ground water systems in the early 1970s. Bioremediation of Petroleum and Petroleum Products: Summarizes the pros and cons of remediation of petroleum and petroleum-based products, from an environmental perspective; Gives examples of unethical behavior and how they should be corrected; residual energy stimulates bacterial growth, anaerobic bacteria rely on iron and nitrates as electron acceptors to oxidize pollutants, those found naturally at a polluted site are often isolated,, grown, and studied in a lab and then released back intro treatment environments in large numbers, scientists are studying the genomes of organisms that are currently used or may be used for bioremediation. Many pathways and different types of enzymes are involved in this process. The results showed that the degradation rate was related positively to the amount of inoculation, when the dose was increased to 0.6 mg x kg(-1), total petroleum hydrocarbon (TPH) degradation rate was 87% in 48 days. Bioremediation strategies can be applied in situ or ex .
