Abstract

The carbamate insecticide carbaryl, at concentrations of 10 mg/l and above, significantly stimulated glutathione reductase (GR) and superoxide dismutase (SOD) activity in the cyanobacterium Nostoc muscorum. A low content of total glutathione (GSH + GSSG), decreased photosynthetic activity, and an increased level of H2O2 was observed in pesticide treated cyanobacteria. As no glutathione peroxidase was observed in this species, stimulation of GR and SOD activity, higher production of H2O2, and low glutathione level was attributed to the utilization of GSH to remove H2O2 spontaneously and nonenzymatically under conditions of pesticide toxicity.
