Development of new algal growth inhibition method using an electrolytic oxygen generated by SPE membrane technology

为了开发一种新的抑制浮游植物生长的方法，利用SPE膜技术对电解制氧器进行了改进。 结果表明，OPE通气条件下，几种浮游植物的细胞生长受到抑制。 同时还观察了微囊藻毒素（MCs）的降解、MCs的产生。铜绿假单胞菌无电解质。 结果发现，这些影响可能是由于活性氧物种（臭氧和OH自由基）的OPE与氧气。 这些结果表明，OPE处理是一种很有前途的方法，抑制浮游植物的生长，MCs的生产，而不产生任何有害的毒素。

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.
