  • Title: Microbial degradation of the organophosphate pesticide, Ethion.
    Author: Foster LJ, Kwan BH, Vancov T.
    Journal: FEMS Microbiol Lett; 2004 Nov 01; 240(1):49-53. PubMed ID: 15500978.
    Abstract:
    The organophosphate pesticide, Ethion, remains a major environmental contaminant in rural Australia and poses a significant threat to environmental and public health. The aerobic degradation of Ethion by mesophilic bacteria isolated from contaminated soils surrounding disused cattle dip sites was investigated. Two isolates, identified as Pseudomonas and Azospirillum species, were capable of biodegrading Ethion when cultivated in minimal salts medium. The abiotic hydrolytic degradation products of Ethion such as Ethion Dioxon and O,O-diethylthiosphosphate were not detected. The data suggest the rapid degradation of Ethion to support microbial growth. The results have implications for the development of a bioremediation strategy.
