Method for producing microorganism culture medium using brewer's yeast

摘要

The present invention relates to a method for preparing a yeast slurry by autolizing yeast slurry at 30 to 60C for 6 to 10 hours, then digesting the endogenous protease for 14 to 18 hours to oligopeptide, Treated for 28 hours to decompose into an amino acid form, and the decomposed solution is centrifuged to remove the supernatant, and the filtrate is concentrated to a concentration of 50%, followed by spray drying, thereby producing a yeast extract for culture.
