Abstract：The effect of four kinds of culture modes (batch culture,quantitative fed-batch,fed-batchbased on pH and total replacement of medium) on green growth and astaxanthin accumulation byHaematococcus pluvialis was investigated.The results showed that total replacement of medium pro-moted cell division effectively.At the same time,the proportion of motile cells reached 98.26％,indi-cating high bioactivity of algal cells.The numbers of algal cells reached 8.60E+05 cells/mL after 9days,while the cell dry weight was 1.12 g/L and astaxanthin production was 53.21 mg/L,which weresignificantly higher than the other three culture modes.Therefore,total replacement of medium is asuitable culture mode for algal cells growth and astaxanthin accumulation in Haematococcus pluvialis.
