In vitro Degradation of DDT by Intestinal Contents of Atlantic Salmon ( Salmo salar )

Fresh mid- and hind-gut contents of young, hatchery-reared Atlantic salmon degraded p,p′-DDT to p,p′-TDE in vitro. Most of the ability to degrade DDT, attributable to intestinal microflora, was eliminated by streptomycin and by heat-sterilization of the gut contents. Since TDE is less toxic than DDT...

Description
Summary:Fresh mid- and hind-gut contents of young, hatchery-reared Atlantic salmon degraded p,p′-DDT to p,p′-TDE in vitro. Most of the ability to degrade DDT, attributable to intestinal microflora, was eliminated by streptomycin and by heat-sterilization of the gut contents. Since TDE is less toxic than DDT, the activity of intestinal microorganisms may increase the chances of survival of fish that ingest DDT-contaminated prey.
