Corn steep liquor powder is a byproduct of corn starch. Corn steep liquor powder contains a large amount of sulfite, polysaccharide, protein and amino acids. Corn steep liquor powder is mainly used as water-soluble fabric protein and water soluble cellulose. A small part of corn steep liquor powder is used for amino acid fermentation, and biotin and restrictive amino acids have great influence on the fermentation of various amino acids. In penicillin fermentation medium, the content of corn steep liquor powder has a great influence on the technical parameters of mycelium.

Corn steep liquor powder can replace expensive organic nitrogen source. After adjusting the production process, the problem of poor stability of corn steep liquor powder can be solved by adding hydrolysate and strict detection before use, so as to make full use of corn steep liquor powder in the process of microbial fermentation.

The by-products of corn steep liquor powder can be prepared by wet film method. Corn steep liquor powder contains many sulfites, peptides, polysaccharides, proteins and various amino acids. Corn steep liquor powder is mainly used for water-soluble tissue protein, fermentation nitrogen source, water-soluble microorganism, fiber feed and fertilizer additive. Most of the chemical components in corn steep liquor powder are synthesized by fermentation.

Only a small part of corn steep liquor powder is used for amino acid fermentation. Corn steep liquor powder used as organic nitrogen source in amino acid fermentation can improve the value of corn steep liquor powder and reduce the cost of amino acid production. In penicillin fermentation medium, the content of corn steep liquor powder has great influence on mycelium, sugar metabolism, fermentation cycle and fermentation efficiency.

Corn steep liquor powder also contains trace metal elements. After concentration, the corn steep liquor powder is sticky, with a paste like fragrance and yellow brown. The soluble nutrients of corn steep liquor powder soaking liquid are rich in nutrition and high in nutritional value.
