Descripción

General description

Corn steep liquor, a by-product of the corn wet-milling industry consists of 50% water and several ingredients like, sugars and proteins. It is a viscous liquid by-product with a pH of 3.7 to 4.1.

Application

Corn steep liquor has been used:

• as a component in broth to act as indicator for starch utilizationas a component in fermentation medium, low-cost medium and in LB medium for the simultaneous saccharification and co-fermentation (SSCF) test
• as a component in fermentation medium for optimization studies

Corn steep liquor is useful as an inexpensive alternative to peptone for a wide variety of microbiological production methods, including fed-batch production of recombinant proteins in E. coli., high density culture of S. cerevisiae, and fermentative production of lactic acid.

Biochem/physiol Actions

Corn steep liquor can be used as a best alternative for yeast extract, as a nitrogen source in biochemical industries. The vitamins, minerals and nitrogen present in the liquor can be used for fermentation.
