Embodiment Construction

[0025] 1) Pick a ring of bacteria from the Saccharomyces cerevisiae, Geotrichum candidum, Candida adenidae, and Candida tropicalis from the Saccharomyces cerevisiae species preserved on the slant, inoculate them into 0.5 L wort seed medium, and inoculate them at 28°C Temperature, 120rpm, shaker culture for 48 hours, so that the number of viable bacteria reached more than 106 / ml, equal volumes of mixed seed culture solution of the four strains, to obtain 2L yeast compound seed solution.

[0026] 2) Pick a ring of bacteria from the original species of Aspergillus oryzae and Aspergillus niger that were preserved on the slant, inoculate them into 1 L of Chase seed medium, and culture them on a shaker at 28°C and 120rpm for 72 hours , stop the cultivation, make the number of viable bacteria reach more than 106 / ml, mix the seed culture solution of the two strains in equal volumes, and obtain 2L mold compound seed solution.

[0027] 3) Mix 2L yeast compound seed liquid and 2L mold co...

Abstract

The invention provides a preparation method of feed protein peptide without probiotic bacteria activity resistance. The preparation method comprises the following steps of: transforming cheap oil cake materials to the feed protein peptide without the probiotic bacteria activity resistance by a microbial fermentation manner, wherein zymocyte is multiple microorganisms comprising anti-nutritional factor degrading bacteria, an animal probiotic group, and a bioactive peptide production group. A product obtained by utilizing the preparation method is feed protein with three characteristics: 1, no resistance, namely, the protein does not contain anti-nutritional factors; 2, probiotic, namely, the protein is rich in animal probiotics; 3, activity, namely, the protein is rich in bioactive peptide. The feed protein is used for animal feeding, is easily absorbed, has a high biological value and has functions of regulating immunity, preventing and resisting diseases and the like.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a method for preparing feed protein peptides. technical background [0002] Since the 1950s, the addition of antibiotics to animal diets has significantly boosted animal production and contributed significantly to the development of intensive animal husbandry. However, with the passage of time, the harm of adding antibiotics in feed has become increasingly apparent, and has received widespread attention from the society. In 2004, WTO, the Food and Agriculture Organization of the United Nations (FAO) and the World Organization for Animal Health (OIE) jointly held a symposium to discuss the use of non-human antibiotics and antibiotic resistance. Since January 2006, the European Union has banned the addition of antibiotics in livestock and poultry feed. It is currently an internationally recognized food safety standard that antibiotics must not be added to pigs and...
