The invention relates to a method for removing griseofulvin in biological medicine waste residues. The method for removing the griseofulvin in the biological medicine waste residues specifically comprises the following steps of (1) a pretreatment process including the sub-steps that (1-1) the to-be-treated biological medicine waste residues containing the griseofulvin is mixed with water, and waste residue slurry with the solid content being 5%-45% is prepared through slurry mixing and dispersing, and (1-2) the waste residue slurry is sterilized; and (2) a catalytic and oxidative degradation process, specifically, catalytic and oxidative degradation is conducted by adding an oxidative and catalytic agent into the sterilized waste residue slurry, and then filtering separation and drying are conducted. Compared with the prior art, a wet catalytic and oxidative treatment integrated technique is used for removing the griseofulvin left in the waste residues, the removal rate is high, secondary pollutants are avoided, and harmless treatment is achieved; the concentration of the griseofulvin left in the waste residues can be rapidly decreased to 0-50 ppm from the original 1000-5000 ppm, the mass reduction rate of the biological medicine waste residues is smaller than 10%, and the method has extremely good application prospects.

The invention discloses a culture medium for producing fermentation by fermentation, which comprises a seed culture medium and a fermentation medium. In the process of fermentation culture, when total sugar reduces to 2.0-3.0%, a feed supplement culture medium is added; and corn is used as a main carbon source to prepare the fermentation culture medium. Preferentially, the seed culture medium and the feed supplement culture medium are also prepared by using the corn as the main carbon source. Since the price of corn flour is much lower than that of rice flour, the production cost is greatly reduced; in addition, the corn flour has sufficient supply and stable quality, thereby ensuring the stability of fermentation production.
