mechanism of action
1. Yeast nucleotide
Nucleotide (Nucleotide, NT for short) is formed by linking nitrogen-containing bases, ribose or deoxyribose, and phosphate. It is the basic unit of nucleic acid and plays an important role in organisms. The addition of exogenous nucleotides can have a significant impact on the gastrointestinal immune system and liver function of animals. Under specific conditions, nucleotides need to be supplemented to ensure the normal physiological functions of the body.
2. Yeast β-glucan
β-glucan (β-Glucan) is one of the most important structural components of yeast cell wall, most of which are water insoluble or colloidal particles. Different from other sugars, the monosaccharides of general sugars are bound by β-1,4 bonds, while the monosaccharides in β-glucan are connected by β-1,3 bonds and β -1,6 bonds. Due to the special bonding method and the existence of molecular hydrogen bonds, β-glucan has a spiral molecular structure, and its special configuration is easily accepted by the immune system. Studies have shown that β-glucan is the matrix of immune response, which can stimulate the proliferation of lymphocytes in animals, activate the complement of macrophages in animals, promote the formation of antibodies and induce the production of interferon, and enhance its cellular immunity And humoral immune function, thereby improving the body's specific and non-specific immune function, improving animal health, and improving survival rate.
Preparation of strains
the strains used are brewer's yeast (Scerevisiaec Hansen) and red pseudomonas (Rhodopseudomonas). Compound culture in liquid medium. The composition of the culture medium is: glucose 3%, ammonium sulfate 0.5%, calcium carbonate 0.003%, sodium chloride 0.02%, yeast extract 0.2%, sterilized at 121 ℃ for 30rain, cooled and connected with the above two strains. Culture conditions: 30±1 ℃, intermittent ventilation, ventilation of 1:0.5-1:0.8 vvm, stirring speed of 150 r/min, culture of 2-3 d, that is, mature seed liquid.
