This invention relates to the field of feed production technology, specifically a method for preparing a substitute for corn feed. The preparation steps are as follows: S1, pretreated giant reed grass is placed in a mixed solution of water, ethanol, and acetic acid to obtain a primary filtrate and a primary filter residue; S2, the primary filtrate obtained in step S1 is mixed with pretreated edible mushroom residue to obtain a secondary filtrate and a secondary filter residue; S3, the secondary filter residue is mixed with water to obtain a mixture, and *Thiobacillus ferrooxidans* and *Thiobacillus thiooxidans* are added to the mixture for fermentation, followed by centrifugation and filtration to obtain a tertiary filter residue; S4, the tertiary filter residue is mixed with the primary filter residue and the secondary filtrate, and laccase, lactic acid bacteria, *Lactobacillus plantarum*, and yeast are added for fermentation to obtain the finished feed product. This invention prepares feed through the joint fermentation of edible mushroom residue and giant reed grass, which can effectively replace corn feed, and the feed has a low heavy metal content.

The application discloses a method for producing prodigiosin by fermentation of sugarcane molasses and beet molasses. According to the Serratia marcescens PG-Zeno-001 strain developed by the company in the early stage, on the one hand, the by-product of the sugar industry, sugarcane molasses and beet molasses, is used as the carbon source for the production of prodigiosin by optimizing the formula of the fermentation medium; on the other hand, the method for producing prodigiosin by fermentation using the fermentation medium is provided, and in the large-scale fermentation of a 100L fermentation tank, the prodigiosin yield is up to 16.18 g / L at 48 h. The application can greatly reduce the cost of prodigiosin fermentation production, and is expected to build a new closed loop for the environment-friendly production of the sugar industry.
