2results about How to "Improve digestive enzyme activity" patented technology

The application discloses a kind of fermented feed fermented by three strains of probiotics of Bacillus YA ( Bacillus sp ), yeast Y ( Saccharomyces cerevisiae ) and capsular red bacteria R3 ( Rhodobacter capsulatus ), and preparation method and application in aquaculture thereof, and viable count is not less than 1×10 7 CFU / g.The fermented feed is replaced ordinary feed according to certain proportion, and feeding result shows that aquaculture water quality is significantly improved after adding fermented feed, and fish growth performance, digestive enzyme activity, immunity, and muscle quality are also obviously improved.Using the feed in suitable range can shorten growth cycle, reduce cost, improve aquaculture environment, reduce antibiotic use, and improve muscle quality of farmed animals, with good economic and ecological benefits, simple fermentation process, low cost, and suitable for industrial large-scale production.

This invention relates to the field of microbial fermentation feed technology, and discloses a zero-wastewater feed ingredient production method based on two-stage fermentation. The method includes inoculating *Bacillus bellis* into a liquid fermentation medium for liquid fermentation to obtain a liquid fermentation mixture; centrifuging all of the liquid fermentation mixture to obtain *Bacillus bellis* cells and collecting the supernatant containing the remaining *Bacillus bellis*; adding yeast and lactic acid bacteria to the collected supernatant, then mixing it with solid fermentation raw materials to form a solid-liquid mixture; adding purified water or solid fermentation raw materials to control the fermentation moisture content; and then fermenting the moisture-adjusted solid-liquid mixture under sealed conditions to obtain a pre-fermented mixture as the feed ingredient. This invention avoids wastewater generation during the production process and improves the digestive enzyme activity of the product.
