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 treatment of hydrocarbon-contaminated Arctic soils: influencing parameters.
The Arctic environment is very vulnerable and sensitive to hydrocarbon pollutants. Soil bioremediation is attracting interest as a promising and cost-effective clean-up and soil decontamination technology in the Arctic regions. However, remoteness, lack of appropriate infrastructure, the harsh climatic conditions in the Arctic and some physical and chemical properties of Arctic soils may reduce...
متن کاملBioremediation of organic contaminated soils*
The term bioremediation covers a wide variety of engineered systems which utilize microorganisms to degrade, detoxify and immobilize organic contaminants. These systems include: l solid-phase treatment using unlined iand treatment systems or prepared bed bioreactors, l slurry-phase treatment systems completed either in-place or within tanks or impoundments, and l in situ treatment systems. Bior...
متن کاملBacterial diversity in the active stage of a bioremediation system for mineral oil hydrocarbon-contaminated soils.
Soils contaminated with mineral oil hydrocarbons are often cleaned in off-site bioremediation systems. In order to find out which bacteria are active during the degradation phase in such systems, the diversity of the active microflora in a degrading soil remediation system was investigated by small-subunit (SSU) rRNA analysis. Two sequential RNA extracts from one soil sample were generated by a...
متن کاملBioremediation of Uranium Contaminated Soils and Wastes
Contamination of soils, water, and sediments by radionuclides and toxic metals from uranium mill tailings, nuclear fuel manufacturing and nuclear weapons production is a major concern. Studies of the mechanisms of biotransformation of uranium and toxic metals under various microbial process conditions has resulted in the development of two treatment processes: (i) stabilization of uranium and t...
