Corn steep liquor powder（CSL powder）is a new organic nitrogen source with rich nutrients.Corn Steep Liquor Powder is rich in carbohydrates, amino acids, peptides, degradable proteins and trace elements and other nutrients. Corn Steep Liquor powder is widely used in antibiotic industry,vitamin, amino acid , enzyme preparation and other fermentation industries.Corn steep liquor powder can promote biosynthesis of various amino acids and enzymes, so it is often used as an organic nitrogen source, water-soluble plant protein and water-soluble vitamin as nutrient supplement in fermentation engineering.

Composition analysis:

Here are some case studies:

1. corn steep liquor can be used as an economical nitrogen source for biosuccinic acid production by Actinobacillus succinogenes.

    “The current study aimed at replacing yeast extract- a costly nitrogen source with corn steep liquor for economical production of bio-succinic acid by Actinobacillus succinogenes 130Z. In this study, a final succinic acid concentration of 20.6 g/L was obtained from the use of corn steep liquor as the nitrogen source, which was comparable with the use of yeast extract as the nitrogen source that had a final succinate concentration of 21.4 g/l. In terms of economical wise, the price of corn steep liquor is very low, which was one fifth of the cost of yeast extract.Therefore, corn steep liquor can be considered as a potential nitrogen source in biochemical industries instead of the costly yeast extract.”

2. Biosurfactant production by Bacillus subtilis using corn steep liquor as culture medium

  “In this work, biosurfactant production by Bacillus subtilis #573 was evaluated using corn steep liquor (CSL) as culture medium. The best results were obtained in a   culture medium consisting of 10% (v/v) of CSL, with a biosurfactant production of about 1.3 g/l. To the best of our knowledge, this is the first report describing biosurfactant production by B. subtilis using CSL as culture medium. Subsequently, the effect of different metals (iron, manganese, and magnesium) on biosurfactant production was evaluated using the medium CSL 10%. It was found that for all the metals tested, the biosurfactant production was increased (up to 4.1, 4.4, and 3.5 g/l for iron, manganese, and magnesium, respectively). When the culture medium was supplemented with the optimum concentration of the three metals simultaneously, the biosurfactant production was increased up to 4.8 g/l. Furthermore, the biosurfactant exhibited a good performance in oil recovery assays when compared with chemical surfactants, which suggests its possible application in microbial enhanced oil recovery or bioremediation. ”

 Corn Steep Liquor Powder is a new alternative to traditional Corn Steep Liquor. Different from the traditional processing technology, it’s a low-temperature spray-dried powder solid, therefore,the finished product has no coking phenomenon, and the active ingredients is well preserved.For both buyers and sellers it is easy to transport,store and use,meanwhile,it is not easy to deteriorate under dry conditions,and composition of CSL powder is stable and uniform.So in practical application,more Fermentation factory merchants choose Corn Steep Liquor Powder.
