Biodegradation of Aged Residues of Atrazine and Alachlor in a Mix-Load Site Soil by Fungal Enzymes

Figure 2

Production of atrazine metabolites during preliminary enzyme test in aqueous cultures. (a) Treatment 1 (EES only). (b) Treatment 2 (EES and H₂O₂). OIET = atrazine-2-hydroxy, CAAT = atrazine deethyl deisopropyl, OAAT = atrazine deethyl deisopropyl-2-hydroxy, CEAT = atrazine deisopropyl, OIAT = atrazine deethyl-2-hydroxy.
