Response of enzymes involved in the processes of antioxidation towards benthiocarb and methylparathion in cyanobacteria Nostoc muscorum

Cyanobacteria are an important source of nitrogen fixation in rice paddies. However, the organophosphate and carbamate pesticides frequently used in rice cultivation can have an adverse effect on these bacteria. The effects of the organophosphate pesticide methylparathion and of the carbamate pestic...

Description
Summary:Cyanobacteria are an important source of nitrogen fixation in rice paddies. However, the organophosphate and carbamate pesticides frequently used in rice cultivation can have an adverse effect on these bacteria. The effects of the organophosphate pesticide methylparathion and of the carbamate pesticide benthiocarb on Nostoc muscorum, a species of cyanobacteria, were evaluated. Cyanobacteria glutathione reductase activity seems to increase with pesticide concentrations, as does superoxide dismutase activity. However, glutathione content decreased as a result of pesticide exposure.
