Free and immobilized microbial systems – potential effective radioactive decontaminators

Abstract

Romanian uranium extractive industry represents the major cause for the environmental radioactive pollution. Radionuclides’ migration into the water and soil generates nutritional imbalances, which cause plants and animals ailment and threats people’s health condition. The biotechnologies based on radioactive ions bio-accumulation, bio-fixation and bio-precipitation processes seem to be a better remediation alternative to the conventional ones. Thricoderma harzianum’s uranium recovery efficiency was more than 85% when it was immobilized on a polyester surface respectively of 90% when it was free.
