NOVELTY - Edible fungi residue probiotic nutrient solution is produced by preparing liquid fungi extract from Bailing mushroom, Pleurotus eryngii and needle mushroom; inoculating mother bacterial strains of Lactobacillus acidophilus, Lactobacillus plantarum and Lactobacillus lactis into culture medium I containing 10-20 ml of liquid fungi residue extract; inoculating mother bacterial strains of Saccharomyces cerevisiae and Torulopsosis utilis into culture medium II containing 20-25 ml of liquid fungi residue extract; and mixing the culture solutions.    USE - Method of producing edible fungi residue probiotic nutrient solution for livestock and poultry (claimed).    ADVANTAGE - The method adopts liquid fermentation, is environment-friendly, energy-saving and convenient to operate than common fungi residue. The solution is brown, slightly bitter and a bit of the fragrance of edible fungi, contains various lactic acid bacteria groups and yeast groups, is convenient to use, and has high palatability to livestock and poultry. It helps improving the appetite of livestock and poultry and accelerates the absorption of nutriments and the growth of livestock and poultry.    DETAILED DESCRIPTION - Producing edible fungi residue probiotic nutrient solution comprises: (A) crushing one or more of mature Bailing mushroom, Pleurotus eryngii and needle mushroom into 1-5 mm pieces, adding 1-2-fold water, boiling the pieces at 95-100 degrees C for 2-3 hours, filtering, separating filtrate from dregs, adding high-temperature filtrate into a sterilized storage tank, adding germfree air and remaining the pressure inside at 0.03 MPa to obtain fermenting culture medium; (B) inoculating the mother bacterial strains of L. acidophilus, L. plantarum and L. lactis into the activated culture medium I (every 100 ml of culture medium contains 1-2 g of glucose, 0.5-1.0 g of corn flour, 0.01 g of mono potassium phosphate (KH2PO4) and 10-20 ml of liquid fungi residue extract; pH value of the culture medium is regulated by running water to 5.5-6.0; then the culture medium is sterilized at 121 degrees C for 30 minutes), standing, culturing at 27-37 degrees C for 60 hours to obtain lactic acid bacteria seed solution, adding the liquid fungi residue extract into a sterilized fermenting tank A in germfree condition, inoculating 1-3 vol.% of lactic acid bacteria seed solution into the fermenting tank culture medium, sealing the fermenting tank, culturing the culture medium at 32-37 degrees C for 5-7 days to obtain fermenting culture solution I; (C) inoculating the mother bacterial strains of S. cerevisiae and T. utilis into the activated culture medium II (every 100 ml of culture medium contains 1-2 g of glucose, 0.5-1.0 g of corn flour, 0.03-0.05 g of KH2PO4 and 20-25 ml of liquid fungi residue extract; the pH value is regulated to 6.5; and is sterilized at 121 degrees C for 30 minutes), adding germfree air, culturing the bacterial strains at 28 degrees C for 32 hours to obtain yeast seed solution, adding the liquid fungi residue extract into a sterilized fermenting tank B, adding germfree air, keeping the pressure inside at 0.03 MPa, inoculating 0.3-0.5 vol.% of the yeast seed solution into the fermenting tank, adding germfree air, and culturing the bacterial strains at 24-28 degrees C for 2-3 days to obtain fermenting culture solution II; and (D) mixing and packing the fermenting culture solution I with fermenting culture solution II according to volume ratio of 2:1. An INDEPENDENT CLAIM is included for edible fungi residue probiotic nutrient solution for livestock and poultry produced by the above method.
