Antioxidant enzymes including SOD, CAT, GR, GSH-PX and GST of Phaeodactylum tricornutum were triggered by EMA to protect cells from oxidative damage. [Display omitted] ► EMA is a novel allelochemical for controlling marine microalgae. ► EMA exposure results in accumulation of ROS and lipid peroxidat...
