  • 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: 9488960
    Abstract: Described are methods and apparatuses for manufacturing ultralong fiber Bragg gratings with arbitrary reflection wavelength. The method may include: generating two holographic beams entering a fiber with a certain intersection angle there-between from one side of the fiber and forming holographic interference fringes in the fiber, driving the two holographic beams to scan along the fiber by a motorized translation stage controlled by a computer; and adjusting the intersection angle between the two beams by motorized rotation stages or motorized mirror mounts controlled by the computer. The present disclosure can be applied in manufacturing ultralong fiber Bragg gratings with arbitrary reflection wavelength, such as narrow-reflection-band gratings, chirped gratings, and apodized gratings, etc.
