ABSTRACT
The Acetobacter xylinum and Schizosacchromyces sp. were isolated from tea fungus culture. Each strain 's function on the production of antibacterial protein was explored by single-strain culture and double-strain culture under various condition. The preliminary conclusion is that the protein is synthesized by the yeast cells and its antibacterial activity is significantly improved through modification by bacteria enzymes. The results of co-cultures of several yeasts with the Acetobacter xylinum show that Schizosacchromyces is superior to other yeasts.
ABSTRACT
Objective:To explore the effect of Weishenjiang Liquor on immune function in mice.Methods: Feeding mice with 8.5, 17, 50ml/kg Weishenjiang Liquor which contains 10mg/dl polysaccharide continuously for 28d, were determined the spleen index, chest gland index, phagocytosis of monocytes phagocytes, activity of NK cell, hemolysin formation, lymphocyte transformation and DTH test.Results: Phagocytosis of monocytes phagocytes, NK cell activity, hemolysin formation, lymphocyte transformation rate were increased in mice with a dose of 50ml/kg group. Conclusions: Weishenjiang Liquor has the function of strengthening cellular and humoral immunization in high dose.
