Abstract: The application discloses a method for preparing crude polysaccharides based on synergistic fermentation with corn stover and fungus, including the following steps: step (1): drying corn stover, pulverizing, placing in a hydrothermal reactor, adding deionized water, sealing the hydrothermal reactor, placing in a heating device, reacting, taking out reaction products, centrifuging and drying a solid; step (2): adding the products obtained in step (1) and dried bean curd residue to a container, adding distilled water, mixing uniformly, sterilizing to obtain a mixed material, inoculating a fungus inoculum under aseptic conditions, sealing the container and cultivating in the dark to obtain crude polysaccharides. The disclosure uses corn stover and bean curd residue as raw materials to achieve efficient utilization of discarded biomass, reduce environmental pollution, and improve utilization of corn stover.
