Genetic engineering is a powerful means of accelerating the evolution of new biological
activities and has considerable potential for constructing microorganisms that can degrade …

Abstract Pseudomonas sp. B13 SN45RE is a genetically engineered microorganism (GEM)
that is able to simultaneously degrade mixtures of chloro-and methylaromatics ordinarily …

In this review we discuss the degradation of chlorinated hydrocarbons by microorganisms,
emphasizing the physiological, biochemical, and genetic basis of the biodegradation of …

Increasing quantities of man-made organic chemicals are released each year into the
biosphere. Some of these compounds are both toxic and relatively resistant to physical …

Many microorganisms in nature have evolved new genes which encode catabolic enzymes
specific for chlorinated aromatic substrates, allowing them to utilize these compounds as …

Chlorophenols are chlorinated aromatic compound structures and are commonly found in
pesticide preparations as well as industrial wastes. They are recalcitrant to biodegradation …

The chlorinated phenols comprise a large group of toxic, man-made chemicals that are
serious environmental pollutants. Microorganisms can degrade many, but not all, of the …

The mode of degradation of various halogenated compounds in isolated pure cultures and
the disposition of the degradative genes have been studied. In many cases the degradative …

Microbial enzyme systems may be used in the biodegradation of persistent environmental
pollutants. The three polypeptide components of one such system, the 4-chlorobenzoate …

Contamination of soil and natural water bodies driven by increased organic pollutants
remains a universal concern. Naturally, organic pollutants contain carcinogenic and toxic …
