Low Temperature Ex Situ Bioremediation of Hydrocarbon Contaminated Soils
Many oil degrading bacteria thrive within the mesophilic temperature range, between 20°C and 40°C; bioremediation practitioners view this as the optimal temperature range for microbially driven hydrocarbon remediation. Environmental managers generally halt active bioremediation projects during the winter months as microbial activity is thought to be insignificant and not cost effective. Recent ...
متن کاملBioremediation of phenols and polycyclic aromatic hydrocarbons in creosote contaminated soil using ex-situ landtreatment.
Soil from a former creosoting plant containing phenols and polycyclic aromatic hydrocarbons, was remediated using an ex-situ landtreatment process. Total 16 USEPA priority PAH and total phenol were reduced from 290 mg/kg and 40 mg/kg to < 200 mg/kg and 2 mg/kg, respectively. The bioremediation process involved soil mixing, aeration, and slow release fertilizer addition. The indigenous populatio...
متن کاملBioremediation of Contaminated Soils: A Comparison of In Situ and Ex Situ Techniques
When investigating the treatment of contaminated soils, the application of biotreatment is growing rapidly. Factors influencing this rapid growth include that the bioremediation processes are cost-efficient, safe, and nature-based. In the past, thermal, chemical, and physical treatment methods have failed to eliminate the pollution problem because those methods only shift the pollution to a new...
متن کاملEx-situ Bioremediation of U(VI) from Contaminated Mine Water Using Acidithiobacillus ferrooxidans Strains
The ex-situ bioremoval of U(VI) from contaminated water using Acidithiobacillus ferrooxidans strain 8455 and 13538 was studied under a range of pH and uranium concentrations. The effect of pH on the growth of bacteria was evaluated across the range 1.5–4.5 pH units. The respiration rate of At. ferrooxidans at different U(VI) concentrations was quantified as a measure of the rate of metabolic ac...
متن کاملIn-Situ Bioremediation of Contaminated Ground Water
Walter W. Kovalick, Jr., Ph.D. Director An emerging technology for the remediation of ground water is the use of microorganisms to degrade contaminants which are present in aquifer materials. Understanding the processes which drive in-situ bioremediation, as well as the effectiveness and efficiency of the utilization of these systems, are issues which have been identified by the Regional Superf...
