Laboratory experiments targeting the effect of humic acid (HA) on the cell lysis of cyanobacterium Anabaena circinalis have been performed. Light irradiation was found to be an important factor for the cell lysis phenomenon, whereas intracellular hydrogen peroxide (H2O2) might be a chemical factor for the process. An exogenous H2O2 concentration of 1.0 mg l−1 was determined as the threshold for cell survival. Our results indicated that HA or its possible product(s) of photochemical reaction can… CONTINUE READING
