Abstract
The degradation kinetics of different sources of 2,4-dichlorophenoxyacetic (2,4-D) and atrazine by the natural strain Mo008 of the basidiomycete fungus Trametes versicolor (L.:Fr.) Pilát was studied, knowing that in this process the strain used produces an enzyme complex composed of manganese peroxidase (MnP), lignin peroxidase (LiP) and laccase, and the response on the global consumption rate and yield is dependent on the 2,4-D source, being more efficient with an analytical source and mixture with atrazine than amine salt; however, it was more efficient to degrade atrazine. The strain studied (Mo008) consumed 1000 ppm of 2,4-D analytical, 2,4-D amine, 2,4-D plus atrazine and atrazine in 750, 850, 650 and 550 h, respectively.
Key words: Trametes versicolor, degradation kinetics, biodegradation, 2,4-dichlorophenoxyacetic (2,4-D), atrazine.
