Abstract

The process of cultivating haemtococcus pluvialis and producing astaxanthin includes compounding culture medium, one-step production process, circular use of the culture meidum and utilziing CO2 in regualting the pH value of culture liquid, inducing sporification of haemtococcus pluvialis and accumulating astaxanthin. The said process including cell growth of haemtococcus pulvalis, spore conversion and astaxanthin accumulation is completed in the same culture medium inside one identical bioreactor. The culture period may be shortened to 12-15 days, and the culture medium may be reused for at least six times via proper treatment. The production process has no effluent drainage, high astaxanthin yield and quality.
