摘要：Environmental pollution is a major problem which affects biodiversity,public health and ecosystems *** issue cannot currently be solved using conventional technology because these treatments are expensive,ineffective and time *** methods focus unduly on the separation,rather than the destruction of *** use of genetically engineered organisms for bioremediation would be an environmentally-friendly and cost-effective alternative for the management and remediation of pollutants in contaminated *** types of genetically engineered microbes have been developed through recombinant DNA and RNA technologies,these have been utilized for the removal of heavy metals and toxic substances from contaminated *** plants can also mobilize or degrade chlorinated solvent,xenobiotic compounds,explosives and phenolic substances.A symbiotic relationship between genetic engineered microbes and transgenic plants can enhance the effectiveness of bioremediation of contaminated *** review examines recent developments in the use of genetically engineered microbes and transgenic plants for the bioremediation of contaminated *** review will also identify the environmental factors which influence bioremediation by genetically engineered microbes and transgenic plants as well as suggesting future directions for research in these areas.
