Bioremediation 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 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...
متن کاملElectrokinetic Remediation of Mercury-contaminated Soils
A series of batch tests were conducted to investigate the relative desorption potential of mercury from kaolin and glacial till soils under the effect of three extractant agents, namely, KI, NaEDTA and NaCl (all of them with a concentration of 0.1 M). These tests were conducted under different pH conditions (within a pH range between 2 and 12). Also batch tests using deionized water were perfor...

متن کاملPlasmid-Mediated Bioaugmentation for the Bioremediation of Contaminated Soils
Bioaugmentation, or the inoculation of microorganisms (e.g., bacteria harboring the required catabolic genes) into soil to enhance the rate of contaminant degradation, has great potential for the bioremediation of soils contaminated with organic compounds. Regrettably, cell bioaugmentation frequently turns into an unsuccessful initiative, owing to the rapid decrease of bacterial viability and a...
