| Research Abstract |
To develop of a new inhibit method for phytoplankton growth, it was improved electrolytic oxygen generator using SPE membrane technology (Oxygen Productive Electrode: OPE). As a result, under OPE aeration condition suppressed cell growth of several phytoplankton species. It was also observed microcystins (MCs) degradation, MCs productions of M. aeruginosa without electrolytes. It was found that these effects may be due to active oxygen species (ozone and OH radicals) produced by OPE with oxygen. These results demonstrate the OPE treatment is one of the promising method for inhibiting phytoplankton growth, MCs production without producing any hazardous toxin.
