Brown sugar, raw sugarcane juice, and enzymatic hydrolyzates from amilaceous or ligno(hemi)cellulosic sources like cane bagasse turned out to be a minimal but satisfactory culture medium for the production of astaxanthin in Phaffia rhodozyma. The condition for this was a small supplementation (1 g/l) of a nitrogen source. Urea resulted in a preferential yeast biomass increase as compared to soya meal and tannery shavings, the major beneficial effect of which was in the pigment content of the yeast cells.
