Biodegradation of the Herbicide 2,4-D by Some Fungi

Fungi commonly known for diseases generating and fermentation agents, apart from this some fungi show biodegradation agents. Pesticides are used for controlling plant diseases but when spraying the pesticides only 40% goes at target and the rest in soil environment. So the soil be contaminated and as a result of this useful microflora are affected and soil fertility decline. So, some fungi tested against the pesticides 2,4-D (Herbicide) Results reveal that fungi Trichoderma viride, Trichoderma koningii, Penicillium chrysogenum and Rhizopus stolanifer are showing capacity pesticides elimination in soil. The HPLC and Chemical Oygen Dmand (COD) result showed Trichoderma viride, Trichoderma koningii notable removal of pesticides in minimal mineral medium and Penicillium chrysogenum mderate removal of herbicide. The principle reaction involved in the pesticides degradation leading to loss of herbicidal activity and converted into secondary metabolites. The intermediate of these pesticides would convert into simpler environmental friendly compounds on long acclimation with potential microorganisms. Therefore bioremediation of pesticides by the obove isolate microorganisms could be used for remediation of pesticides contaminated soil and water.
