Abstract

The intersectional effect of NaAC,FeSO4 and H2O2 on the accumulation of astaxanthin in Haematococcus pluvialis wall as well as change of total soluble protein were studied during the process of astaxanthin accumulation of Haematococcus pluvialis.Results showed that in the case of nutrition starvation,25 ℃,6000 lx illumination and additionof NaAC(45 mM) and FeSO4(450 μM) could advance 30 days for completing astaxanthin accumulation in H.pluvialis cells,but the production of astaxanthin was lower 7.4% than that of blanks.All the treatments with H2O2 had lethal functions to alga cells such as albescent,alga cells thaw and death.SDS-PAGE results displayed the total the protein soluble protein decreased gradually along the process of astaxanthin accumulation in the Haematococcus pluvialis.It is suggested astaxanthin accumulation in Haematococcus pluvialis might be based on protein degradation and depletion.
