The invention provides screening of
protein-rich thermosynechococcus and a culture method and application of the
protein-rich thermosynechococcus, and relates to the technical field of
algae. The thermosynechococcus sp. LBV 12 is preserved in the China Center for Type Culture Collection on June 27, 2024, and the preservation number of the thermosynechococcus sp. LBV 12 is CCTCC (China Center for Type Culture Collection) NO: 20241317. According to the method, a Yunnan Tengchong hot sea
water sample is separated and purified under the conditions that the temperature is 40-50 DEG C, the illumination intensity is 9000
Lux, the
humidity is 45% and the light-dark ratio is 12 h: 12 h, and dominant
algae strains are screened out according to the
heat resistance degree and the growth condition. The thermosynechococcus shows a remarkable
growth speed in an optimized culture medium, rapidly propagates and reaches
high density, rich
protein can be effectively synthesized and accumulated in the
metabolic process, the content of
essential amino acid is balanced, and the thermosynechococcus can serve as a high-protein source with great potential. And the product is rich in natural
pigment phycocyanin, and has unique color and luster and
oxidation resistance. Therefore, the thermosynechococcus has important application potential in the fields of food, feed, health care products and the like, and particularly provides powerful support for
sustainable development of related industries in the aspect of developing natural products rich in
nutrition.
