The invention relates to a method for preparing special peanut cake powder for fermentation. The method comprises the following steps of: taking non-mildew peanut cake, crushing, passing a 40-mesh mesh sieve, and taking sieved materials to obtain the peanut cake powder; mixing the peanut cake powder and an industrial enzyme preparation, conveying into a double-screw extruding and bulking machine after mixing uniformly, extruding and bulking; drying extruded and bulked materials, and enabling the water content of the materials to be less than 8-12%; and crushing the dried materials by a micro-powder machine while controlling the temperature to be below 80 DEG C in the crushing process to obtain the special peanut cake powder for fermentation. The method has the advantages that not only is the problem for the need of a nitrogen-source culture medium with comprehensive nutrition in industrial fermentation solved and is the need for normal metabolic and synthetic products of microorganisms in the industrial fermentation process met, but also the special culture medium for fermentation can also provide proper precursor substances, coenzymes or cofactors and the like for forming the metabolic products, so that the yield of metabolites is increased.
