Abstract: The growth，floating，specific activity of superoxide dismutase（SOD）and levels of malondialdehyde，water-soluble protein and Chl-a were determined in green alga Spirulina platensis named IS，ES-1，…，ES-8 and ES-9 exposed to electric field for 5 mins at 0，3，6，9，12，15，18，21，24 and 27 kV to evaluate the biological effects of electric field on green the alga.The results showed that there was less malondialdehyde content in the treated strains than in the original strain IS.However，the treated strains had better growth than the original strain IS except for ES-5，with the best floating in ES-8，and the contents of chlorophyll，water-soluble protein and phycocyanin increased by 37.69%，19.13%and 19.26%，respectively and the SOD specific activity increased by 7.06%.The ultraviolet absorption spectrum of Chl-a was shown to be significant variation in peak in ES-8 compared with the original strain，showing the biological effects of electrostatic field on green alga Spirulina platensis.
