Provided is a method of producing an oil containing polyunsaturated fatty acids by usingsp. The method comprises: performing fermentation usingsp.; resuspending the resultant cells after fermentation in water, adding cellulase and neutral protease for enzymolysis; mixing the enzymatic hydrolyzate with n-hexane, shaking, extracting, centrifuging, and collecting the n-hexane phase; concentrating the n-hexane phase under reduced pressure to remove the n-hexane, and drying to obtain an oil; performing a first crystallization and a second crystallization, and then performing cold filtration to obtain a liquid oil after the second crystallization; and subjecting the liquid oil to deacidification and decolorization. By regulating fermentation conditions and conducting concentration processing on polyunsaturated fatty acids, the content of eicosapentaenoic acid in thesp. is increased to more than 12%, and the obtained oil is rich in docosahexaenoic acid, docosapentaenoic acid and eicosapentaenoic acid.

The present invention discloses an intelligent induction miner's lamp. A heat dissipating portion in the miner's lamp includes a substrate, a reflector, and heat sinks; the substrate provided with a first through-hole in the center thereof is arranged on an inner wall of the reflector; an upper surface of the substrate is provided with a plurality of the heat sinks; the substrate, the reflector, and the heat sinks are integrated during casting; the power source cover is provided with a latching switch and is arranged on the reflector; the reflector is provided with a lens whose center is a recessed blind via; the lens is located on a side of a lower surface of the substrate, a ring protrusion is provided around the recessed blind via, and a sensor is arranged in the recessed blind via; the lens, the reflector, and the power source cover form a cavity; a driving power source fixed to the substrate is arranged in the cavity; and the lower surface of the substrate is provided with a light emitting element corresponding to the ring protrusion. In the present invention, the latching switch is arranged on the power source cover. Before the miner's lamp is mounted, whether the miner's lamp has a sensing function can be controlled by using the latching switch. In this way, use of other lamps of the same type is not affected, the costs are low, and mounting, cable layout, and subsequent maintenance are easy.
