摘要: We investigated the intracellular O-2(center dot-), H2O2 and OH center dot generation induced by PA in Microcystis aeruginosa using two targeted fluorescent probes and also determining the SOD activity. We found that PA significantly induces the dose-dependent generation of O-2(center dot-) and consequently H2O2, OH center dot. Under dark condition, when exposed to 50 mg L-1 PA for 8 h, the O-2(center dot-) and H2O2/OH center dot levels in M. aeruginosa were 2.00 and 1.91 folds of the respective control. The light enhanced the O-2(center dot-) formation. The low concentration of PA (5 mg L-1) activated the SOD, but was inhibited gradually with increase in PA concentrations, especially under light condition. The results of this study indicated the significant generation of O-2(center dot-) as precursor of H2O2 and OH center dot, which provided original and direct evidence for the oxidative stress of PA to M. aeruginosa. The results also suggested that the futile redox cycling of PA was the main source of excessive intracellular Or and consequent H2O2 and OH center dot, which induced the allelopathic inhibition of M aeruginosa.
