Release time:
2024-08-21
Corn steep liquor powder can significantly promote the production of proteases, and proteins from corn steep solids can induce microorganisms to produce proteases; Therefore, using corn steep powder as a fermentation substrate is economically feasible.
Enzyme preparations are mainly produced through microbial fermentation and are widely used in fields such as food, medicine, monosodium glutamate, textiles, and health products.
1: Why use corn steep liquor powder as a nitrogen source for large-scale enzyme production?
About 30-40% of the production cost of industrial enzymes is the cost of culture media. Therefore, using low-cost fermentation raw materials to form the culture medium is beneficial for reducing production costs and increasing profits.
corn steep liquor powder is an inexpensive, nutrient rich fermentation material that contains 43% protein, 35% amino acids, as well as a variety of vitamins, mineral nutrients, and other bioactive molecules; Corn steep solids can promote the industrial production of various enzyme preparations, including protease and amylase.
2: Corn steep liquor powder can promote protease production
Protease is an important enzyme in industry, accounting for 60% of the entire industrial enzyme market and widely used in industries such as detergents, leather, textiles, and pharmaceuticals. Corn steep liquor powder can significantly promote the production of proteases, and proteins from corn steep solids can induce microorganisms to produce proteases; Therefore, using corn steep powder as a fermentation substrate is economically feasible.
Corn steep liquor powder can serve as a substrate to promote the production of fibrinolytic enzymes by Chlorella Vulgaris; Fibrinolytic proteases are expensive, but they have good effects on cardiovascular diseases. CSL powder, as a low-cost nitrogen source, has high stability for the growth of Chlorella Vulgaris. Under the optimized conditions of 0.9% glycerol and 1.2% corn steep liquor, the concentration of microbial cells significantly increased. Under the conditions of 1.1% glycerol and 0.9% corn steep liquor, the protease production is highest. Adding corn steep powder to the culture medium is beneficial for increasing the cell concentration of microorganisms and the production and activity of fibrinolytic enzymes.
3: Corn steep liquor powder can be used as an inexpensive fermentation material for α-amylase and β-galactosidase
Experimental results have shown that adding Corn steep powder to the fermentation medium is beneficial for increasing the production of α-amylase and β-galactosidase, and reducing their production costs. α-amylase can be used for feed processing; β - galactosidase can transform and decompose the anti nutritional factor α - galactosides in feed and soy based foods, improving their nutritional composition; Both have wide applications in various industries such as pharmaceuticals, papermaking, baking, beer brewing, alcohol production, fermentation, and textiles.
Experiments have shown that tryptone and corn steep powder are the most suitable organic nitrogen sources for producing α-amylase and β-galactosidase, but corn steep powder is only 1/5 of the price of peptone, which can significantly reduce production costs. Adding corn steep liquor to the fermentation medium can significantly increase the production of α-amylase and β-galactosidase. In addition, Ca is crucial for the production of α-amylase, and corn steep liquor powder contains 0.15% Ca, which is beneficial for the synthesis of α-amylase.

What are the benefits of applying amino acid powder(NPK 14-0-0) to plants?
Amino acid powder can provide organic nitrogen, and plants can directly absorb and utilize the amino acids in the amino acid powder through roots or leaves, making it easier to produce protein and saving the energy required to produce amino acids.
Corn steep liquor powder: Cost-effective Feed Additive
Corn steep liquor powder can be used as a feed protein source or as food for beneficial microorganisms in feed fermentation (fermentation medium), promoting the growth of beneficial microorganisms, thereby improving the nutritional utilization of feed, reducing feed costs, and improving animal growth performance; it is widely used in feed additives for ruminants, chickens, aquatic feed, etc.
Corn Steep Liquor Powder: High-quality fermented feed ingredients
the use of feed produced by adding CSL powder fermentation can reduce and improve feed digestibility, reduce morbidity, increase daily weight gain, improve feed digestibility, and reduce feed-to-meat ratio, which has extremely high economic value.
Corn steep liquor powder: high-quality nutritional supplement for ruminants
corn steep solids and molasses can safely replace the concentrated feed in the diet, providing cows with abundant energy and protein; And it will not affect the feed intake of cattle. CSL powder contain 43% crude protein, 35% amino acids, 7% organic nitrogen, 21% lactic acid, and 31% carbohydrates. It is commonly used in the feed industry as a protein source for cattle, sheep and other animals.
Corn steep liquor powder: Cheap and High-Quality Bio-stimulant
CSL can be used to improve plant growth and productivity, as well as all negative effects of abiotic stress; Shandong JUCI is a corn steep powder supplier and manufacturer. Corn steep liquor powder is 100% water-soluble, containing NPK 7-7-7, 35% amino acids, 43% protein, reducing sugars, vitamins, minerals, and other biologically active nutrients for soil and crops. Among them, various nutrients such as amino acids and vitamins are part of plant metabolic pathways. The application of corn steep powder can have direct or indirect effects on the physiological processes and metabolic pathways of plant adaptation to biotic and abiotic stress, and can serve as an inducer, directly/indirectly inducing and stimulating effects.
Corn steep liquor powder: High quality organic fertilizer raw materials
the application of corn steep solids can also increase the pH value of the soil, increase effective soil nutrients, thereby accelerating the absorption and utilization of nutrients by crops, promoting crop growth, and early flowering.
