By determining the cell quantity, content of chlorophyll-a, astaxanthin content in Haematococcus pluvialis, the effects of three reactive oxygen species 1O2、H2O2 and ·OH on the growth and the accumulation of astaxanthin content were investigated,, preliminarily seek to the feasibility to enhance the astaxanthin biosynthesis by ROS.The results showed that 1) the content of asataxanthin in Haematococcus pluvialis was obviously increased by proper concentration of MB.When the concentration of MB was 10-7mol·L-1, content of asataxanthin could reach to 5.27μg·mL-1, much higher than the control.2) the growth of Haematococcus pluvialis was restrained by the ROS, but the restraining effect of MB was not so serious as H2O2 and reagent of ·OH.
