The aim of this study was to define the mechanism allowing the green alga Coccomyxa subellipsoidea to break down organophosphates from agricultural run-off. This study found that metabolically active cultures of the microalga C. subellipsoidea breakdown organophosphates (paraoxon, malathion and diazinon) with differing structural conformations in freshwater through a mechanism that requires the formation of reactive oxygen species (ROS) with little to no toxic effects on the algae. Under these conditions, organophosphate levels were reduced to 0.1 mg/mL or less over the 8–10 day experimental period. These findings demonstrate a biological- based system can be tailored for the remediation of …
