QUINTERO DIAZ, Juan Carlos. PESTICIDES DEGRADATION BY WHITE ROT FUNGI: A REVIEW. Rev. Fac. Nac. Agron. Medellín [online]. 2011, vol.64, n.1, pp.5867-5882. ISSN 0304-2847.

Wood white rot fungi are characterized by their capacity of degradation and mineralization of lignin by means of an enzymatic extracellular system, which mainly consists of lignin peroxidase (LiP), Manganese peroxidase (MnP) and Laccase. During the last twenty years, these fungi and their enzymatic ligninolytic system have been the focus of attention to study the degradation capacity of a wide range of xenobiotics as pesticides, dyes, explosives, etc. However, a large number of xenobiotics are not responding to ligninolytic enzymes biodegradation process. This situation has permitted the discovering of new mechanisms used by fungi as citochrome P-450 monooxygenases oxidation system, and transferases' reductive system, widely identified in phase I and II of superior animals' metabolism. The tree types of known degradation mechanisms used by fungi in environmental contaminants degradation and some other examples of degradation mechanisms in pesticides will be described and analyzed in this review.
