Abstract: Astaxanthin is a kind of pigments that has broad market prospects and has antioxidant; anticancer; Prevention of atherosclerosis; Protect the eyes and central nervous system of health biological Effects. Chemically synthesized Astaxanthin and Crustaceans animal waste processing have some shortcomings that High cost and Production requirements for harsh. Produce Astaxanthin for zymotechnics is the lowest cost way to Produce Astaxanthin( Is the main medium for the low price) .single factor and mixture design experiments were used to investigate the effects of nitrogen source and carbon source on Phaffia rhodozyma cultivation and astaxanthin production. NDS used measuring residual amount of glucose. Determine optimization of nitrogen sources and carbon source. The best basic medium was composed of 30g/L glucose, 1.5g/L(NH4)2SO4 2g/LYeast Extract. inoculated in 250 ml shake flasks containing 50ml. Gained Yeast growth curve. In 22 hours after inoculation into the exponential phase of growth yeast. 0 -22 hours in the extension of demurrage ,22-49-hour period to enter the index, thereafter stabilizing.
