Microbial Degradation of a Recalcitrant Pesticide: Chlordecone
Chlordecone (Kepone®) is a synthetic organochlorine insecticide (C10Cl10O) used worldwide mostly during the 1970 and 1980s. Its intensive application in the French West Indies to control the banana black weevil Cosmopolites sordidus led to a massive environmental pollution. Persistence of chlordecone in soils and water for numerous decades even centuries causes global public health and socio-ec...
متن کاملMicrobial degradation of synthetic recalcitrant compounds.
Synthetic compounds, particularly highly chlorinated aromatics, comprise the bulk of the environmental pollutants that somehow must be removed from the environment. Microbial degradation of such compounds is usually very slow, making them highly persistent in nature. Some synthetic compounds, with a lower degree of chlorination are, however, biodegradable; biochemical, genetic, and molecular st...
متن کاملMicrobial degradation of the organophosphate pesticide, Ethion.
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 bio...
متن کاملApplication of microbial hot spots enhances pesticide degradation in soils.
Through transfer of an active, isoproturon degrading microbial community, pesticide mineralization could be successfully enhanced in various soils under laboratory and outdoor conditions. The microbes, extracted from a soil having high native ability to mineralize this chemical, were established on expanded clay particles and distributed to various soils in the form of microbial "hot spots". Bo...
متن کاملPesticide Degradation Kinetics
Typically degradation of a pesticide is a biotic process, however, there are abiotic degradation processes as well. The latter include photodegradation (that can produce a wild array of products) and various types of chemical degradation processes. Restricting degradation to the soil interior (no photodegradation component) and assuming negligible chemical degradation, pesticide degradation is ...
