Butanol is an important organic chemical raw material, widely used, mainly used in dibutyl phthalate (DBP), fatty acids, butyl phosphate, butyl acrylate and acetate; butanol is a new renewable energy, its calorific value is higher than ethanol, can be mixed with gasoline in any proportion. Acetone butanol fermentation is a traditional batch fermentation. Since the founding of the people's Republic of China, corn flour has been used in the industrial production of acetone butanol fermentation. At the same time, a stable fermentation process has been formed. In recent years, mankind has attached great importance to the use of renewable resources to produce chemical raw materials and energy materials. At present, one of the important factors limiting the development of butanol fermentation industry is the high cost of fermentation substrate. Looking for low-cost fermentation substrate plays a decisive role in the development of butanol fermentation industry.
Corn steep liquor powder is made from corn steep liquor through low temperature, instant heating and spray drying. The water-soluble protein is well preserved, and its moisture content is less than 8%. It is easy to store and transport. It is a new product of corn syrup. In a starch plant with an annual output of 300000 tons, the dry matter content of corn steep liquor powder is 6% - 8%, the protein content is more than 40%, and the COD content is 80 000-90 000 mg / L. The annual production of corns steep liquor powder is as high as 350000 tons. Corn steep liquor powder can promote the biosynthesis of penicillin and other antibiotics, and is widely used as an organic nitrogen source in microbial growth. Butanol was produced by corn steep liquor powder fermentation, and the simplified medium composition based on starch corn steep liquor powder was optimized for butanol fermentation. The results showed that the total solvent yield of fermentation medium composed of 5.5% starch, 8.5% corn steep liquor powder solution and 0.2% KH2PO4 was 19.3 g / L. In P2 medium, corn steep liquor powder was used to replace the nutrient elements other than glucose, and a better solvent yield was obtained.

Corn Steep Liquor Powder: A New Choice for Organic Agricultural Fertilizers
Selecting an efficient and eco-friendly organic fertilizer is crucial for enhancing soil quality and promoting crop growth. Corn Steep Liquor (CSL) powder emerges as a novel option in the realm of organic agricultural fertilizers.
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.
