Rice chaff and defatted rice bran, by-products in rice processing industry, were used as raw materials for carotenoid production by fermentation of Neurospora crassa, which was high-yield cellulase and β-carotene and gotten from the traditional fermented food in Jiangxi. This paper had studied the optimal fermentation process of carotenoid production with rice chaff and defatted rice bran as raw materials by this strain, and the optimized carotenoid extraction process and the content, monomer and stability ...
