What is Aspergillus Niger?

Aspergillus niger belongs to the subphylum Deuteromycotina, Hyphospora, Hyphospora, and Arbuscularis. It is a common species of filamentous fungi, which is widely distributed in food, plant products and soil. Humans have a long history of using Aspergillus niger. As early as ancient China, people used Aspergillus niger to make sauces, soy sauce, rice wine and so on. Because Aspergillus niger grows vigorously, has a short fermentation cycle, and does not produce toxins, it has been certified as a safe strain by the US FDA. Aspergillus niger enzyme has a strong ability to express foreign genes and efficient egg expression, secretion and modification capabilities. At the same time, the recombinant has high genetic stability.

As more and more foreign proteins are successfully expressed in Aspergillus niger and proved to have high yield and activity, Aspergillus niger has become an important enzyme expression system and has gradually become an important strain for the production of industrial enzyme preparations. According to reports, Aspergillus niger can produce cellulase, xylanase, amylase, protease, glucoamylase, pectinase, and lipase. Industrial enzymes produced by Aspergillus niger have played a huge role in starch processing, fermentation, brewing, beverage production, animal feed, and paper industry.

1. Aspergillus niger can improve the nutrient level and digestion and absorption rate of fermented feed. The microorganisms contained in this product can decompose the macromolecular sugars in the feed into monosaccharides and oligosaccharides, and generate a variety of organic acids, vitamins, biological enzymes, and unknown growth factors, which greatly improve the nutrient level and digestion and absorption rate of fermented feed ;

2. Detoxify the feed. Through the life activities of the microorganisms, the toxic and harmful substances contained in the feed are degraded and removed, thereby greatly improving the safety of the feed;

3. Aspergillus niger Improve the disease resistance of animals. The microorganisms contained in this product directly participate in the barrier function of the animal intestine, supplement the number of beneficial microorganisms in the animal intestine, and prevent the colonization and growth of pathogenic microorganisms through the biological competition mechanism. Restore and maintain the microecological balance of the animal intestine, thereby improving Animal immunity and disease resistance;

4. Aspergillus niger enzyme improve the palatability of feed and significantly increase appetite. Adding this product to feed can improve feed utilization, improve animal production performance, reduce production costs, and improve the breeding environment.
