Abstract
This study was carried out to investigate the effect of herbicide paraquat (1,1-dimethyl-4,4-bipyridilium dichloride) on the electron transport system of the cell. When actively growing cells of bacteria were exposed to the 1.0 mM paraquat, more than $50\%$ of the cells were killed at 0 hour. But specific activities of superoxide dismutase (SOD) were not changed at 0 hour of paraquat treatment. Oxido-reductions of NAD (H) by the suspension of bacterial membtane, rat mithochondria and NAD-dependent dehydrogenase were accelerated by paraquat treatment.
