Abstract: The disclosure discloses a method for processing oil crops with rhodotorula, and belongs to the technical field of fermentation. The method includes the step of inoculating the rhodotorula (such as Rhodotorula mucilaginosa, Sporidiobolus salmonicolor and Rhodotorula glutinis) that can produce carotenoid into a fermentation medium that contains oil-rich oil crops for solid state fermentation to obtain oil and oil crop meal rich in carotenoid. The carotenoid as a fermentative metabolite of the rhodotorula has bioactivities of resisting oxidation, preventing vascular sclerosis, enhancing immunity and preventing cancers. Contents of carotenoid in the oil and oil crop meal acquired by the method can be up to 9.071 μg/g and 8.062 μg/g correspondingly. By the method, the oil and oil crop meal rich in carotenoid can be acquired at the same time by just once fermentation and once oil pressing without additional functional substances, and thus the production cost of the functional oil and the fermentation oil crop meal is greatly reduced.

Abstract: The present invention provides a novel method for improving microbial laccase production, which relates to the field of microbial fermentation. The present invention is to add β-carotene and other types of carotenoids, or microorganisms that produce carotenoids, or mixtures comprising carotenoids into a fermentation system during fermentation of Pleurotus ferulae and other higher fungi. The present invention can improve the laccase production 12 times more than before, with the advantages of a simple process and high yield.
