Why do people like to use corn steep liquor and powder as a nitrogen source to produce lactic acid?
Release time:
2024-07-25
Our corn steep liquor powder is extracted from non-GMO corn and contains 43% soluble corn protein and 7% organic nitrogen; It also contains nutrients such as sugar, minerals, and various vitamins that can be used as growth promoting factors.
Lactic acid has a global market worth billions of dollars and is still growing year by year, with great potential. Using yeast extract as a nitrogen source to produce lactic acid has good results but is expensive, accounting for 38% of the total cost; Therefore, corn steep liquor is very popular as a low-cost alternative nitrogen source for yeast extract.
1: Corn steep liquor powder is a cost-effective industrial fermentation raw material
Our corn steep liquor powder is extracted from non-GMO corn and contains 43% soluble corn protein and 7% organic nitrogen; It also contains nutrients such as sugar, minerals, and various vitamins that can be used as growth promoting factors.
Many studies have shown that the various amino acids and vitamins in CSL powder are very suitable for the growth of lactic acid bacteria; corn steep powder can replace yeast extract as the sole nitrogen source in the fermentation medium; And the price of corn steep liquor powder is only 1/5 of yeast extract, peptone and other materials, which can significantly reduce costs, enhance product profits and market competitiveness!
2: The bio-active molecules such as amino acids contained in CSL powder can enhance fermentation efficiency
Corn steep powder contains 35% amino acids; Among them, amino acids such as leucine, methionine, and glycine are essential nutrients for bacterial growth and have a significant impact on cell biomass. Glutamate and alanine are key substances that make up the structure of cells; Amino acids such as glutamic acid, glycine, and cysteine can reduce cell damage and premature aging. Glutamic acid and arginine can enhance the resistance of lactic acid bacteria to acidic environments. Alanine and lysine are essential substances for the synthesis of cell walls.
The amino acids contained in CSL powder can be utilized by microorganisms, reducing energy consumption and accelerating microbial growth and reproduction. Meanwhile, corn steep powder contains multiple vitamins that play a unique role, such as vitamin B2 and vitamin B3, which can act as reducing agents.
3: Comparison between corn steep liquor and other organic nitrogen sources
The experimenters used various inorganic/organic nitrogen sources instead of peptone and yeast extract to compare the effects of different nitrogen sources on microbial growth and lactate production, such as NH4Cl, urea, peptone, yeast extract, and corn steep liquor; The medium with corn steep liquor added had the highest lactate yield of 9.8 g/L. Due to the high prices of peptone and yeast extract, as well as the cost-effective of corn steep liquor, it can replace the previously used fermentation nitrogen source. It should be noted that excessive corn steep liquor can lead to a decrease in lactate production; This may be due to the high concentration of corn steep liquor disrupting the carbon nitrogen ratio in the culture medium.

Specifically, when the culture medium contained 5 g/L Corn Steep Liquor Liquid and 7.6 g/L sodium glutamate, the absorbance of the red pigment reached 20.7 U, compared to only 12.4 U in the control. This indicates that the addition of Corn Steep Extract significantly increased red pigment production.
Benefits of Adding Corn Steep Liquor Powder to Feed Fermentation
Adding corn steep liquor powder to feed fermentation can positively impact the fermentation process and final results in multiple ways, including nutritional supplementation, fermentation efficiency, and cost control.
Organic farm: Corn Steep Liquor Powder are promoters of tomato seedling growth
Corn steep liquor dry powder has a balanced ratio of NPK 7-7-7 and is 100% soluble in water. It is rich in up to 60% organic matter, which can transport a large amount of carbon source to the soil and effectively improve the physical and chemical properties of the soil. The protein content of Corn Steep Powder is not less than 42%, and the total amino acid content is not less than 35%. These nutrients can be directly absorbed and utilized by crops, providing sufficient nitrogen source guarantee for the growth of tomatoes.
Corn steep liquor powder has a cost advantage and more comprehensive nutrition than amino acid powder. The two can form a synergistic effect in the application of agricultural fertilizers through nutritional complementarity, fertilizer efficiency enhancement and cost optimization, which can achieve the improvement of fertilization effect and optimization of economic benefits.
