Fed-batch carotenoid production by Phaffia rhodozyma Y-17268 using agroindustrial substrates
Abstract:This work aim the carotenoid bioproduction by the yeast Phaffia rhodozyma Y-17268 in a fed-batch bioreactor with different low-cost agroindustrial substrates (crude glycerol, corn steep liquor, and rice parboiling water). The maximum concentration of total carotenoid and cell productivity were 4118 µg/L (835 µg/g) and 0.05 g/L. h, respectively, with a feed volume of 75 mL every 12 h. The medium were composed of 100 g/L crude glycerol, 100 g/L corn steep liquor, and 20 g/L rice parboiling water at 25ºC, pHiniti… Show more
