  • Patent number: 11946088
    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 ?g/g and 8.062 ?g/g correspondingly.

  • Patent number: 5043490
    Abstract: Novel 1,1,2-trifluorodienes, which have a minimum of seven carbon atoms and may contain in their molecule a phenylene or a methylphenylene moiety, are useful monomers, that can be polymerized in the presence of either free radical or coordination catalysts and can undergo selective reactions such, as for example, epoxidation of the vinyl (nonfluorinated) double bond. The resulting perfluorovinyl epoxy compounds also are useful monomers, which can undergo polymerization to useful materials.
