Abstract
The strain of Pseudomonas cepacia, AC1100, capable of utilizing 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) as a sole source of carbon and energy can degrade 2,4,5-T in contaminated soil, removing more than 99% of 2,4,5-T present at 1 mg/g of soil within 1 week. Repeated application of AC1100 even allowed more than 90% removal of 2,4,5-T within 6 weeks from heavily contaminated soil containing as much as 20,000 ppm 2,4,5,-T (20 mg/g of soil). Microbial removal of 2,4,5-T allowed the soil to support growth of plants sensitive to low concentrations of 2,4,5-T. After 2,4,5-T removal, the titer of AC1100 in the soil rapidly fell to undetectable levels within a few weeks.Keywords
