Microbially‐mediated detoxification of five synthetic pyrethroid insecticides was achieved by a mixed culture growing anaerobically at 75°C. These pyrethroids were hydrolysed to non‐insecticidal products after a period of 4–8 weeks' incubation. Of these five permethrin was the most readily transformed and Fastac the most recalcitrant. The mixed culture consisted of a facultative anaerobe and two other obligate anaerobes including a methanogen. This culture was derived from terrestrial sediments from hot‐springs in New Zealand. This is the first reported microbial biotransformation of these xenobiotics at a temperature of 75°C. © 1997 SCI.
