Engineering of improved microbes and enzymes for bioremediation

Bioremediation with microorganisms is an attractive alternative to conventi onal techniques, such as incineration and chemical treatment, for disposing of pollutants. Recent progress in molecular biology, microbiology, and gen etics is providing the driving force towards engineering improved microbes and enzymes for bioremediation. A number of genetic engineering approaches have been developed in the past several years that have proven useful in in troducing/evolving the desired properties for different biodegradative path ways or enzymes. The initial excitement generated in this area should conti nue to pave the way for rational or irrational design of microbes or enzyme s with novel remedial properties.
