Microbial Degradation of DDT.
Abstract
One-half of the marine bacteria tested converted DDT to water-soluble products. Mucor alternans converted DDT to water-soluble metabolites at a rate four times greater than the most active marine bacterium. Techniques were developed to isolate and purify these metabolites. The relationship of chemical structure to biodegradability of DDT analogs was investigated. Para substitution of one of the two aromatic rings with chloro, nitro, hydroxyl, or amino groups significantly reduced the rate of biodegradability. The most resistant compounds were those with both rings containing these substituents. Various environmental factors were examined for their effect on DDT metabolism in marine waters.
