CORN STEEP LIQUOR

The Uses of CORN STEEP LIQUOR

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.

What are the applications of Application

Corn steep liquor is a viscous concentrate of corn solubles, rich in amino acids, and other growth stimulants

Definition

Substance obtained by the partial removal of water from the liquid resulting from steeping corn in a water and sulphur dioxide solution which is allowed to ferment by the action of naturally occurring lactic acid-producing microorganisms.

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.

Flammability and Explosibility

Highly flammable

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.
