The liquid fermentation medium for Monascus fermentation comprises a specific proportion of a carbon source, corn syrup dry powder, peanut protein powder, an inorganic nitrogen source, arginine, ferrous sulfate, inorganic salt and a defoaming agent with a content of not more than 0.05%. The peanut protein powder has a protein content of 55-65 wt% and a fat content of 5-6 wt%. The composition of the liquid fermentation medium is optimized, and the combination of the components can promote the growth of the Monascus strain, improve the production capacity of the strain, and obtain a metabolite with a purple-red appearance and a maximum absorption peak at 505-510 nm.

The invention relates to a multi-grain-boundary cerium-based catalyst as well as a preparation method and application thereof. The multi-grain-boundary cerium-based catalyst comprises a multi-grain-boundary cerium dioxide carrier and an active component loaded on the carrier, the active component comprises any one or a combination of at least two of copper oxide, manganese oxide or cobalt oxide. According to the multi-grain-boundary cerium-based catalyst, multi-grain-boundary CeO2 is adopted as a carrier, and compared with a traditional single-crystal Ce-based catalyst, the multi-grain-boundary Ce-based catalyst has rich grain boundary defects, so that generation of an oxygen vacancy active structure is promoted, and higher photochemical reaction activity is achieved. The structural advantages are beneficial to adsorption and activation of reactants and generation of active oxygen species, so that the deep oxidation performance of the catalyst on VOCs is remarkably improved. Compared with the traditional thermocatalysis, the application of the photothermal catalysis technology reduces the energy consumption of external heating. The multi-grain-boundary cerium-based catalyst has excellent low-temperature degradation capability and reaction stability, so that the multi-grain-boundary cerium-based catalyst has a good application prospect in purification of VOCs (Volatile Organic Compounds) in industrial flue gas.
