CULTIVATION TECHNIQUE INTENTIONALLY CONTROLLING CONTENT OF AMINO ACID, TAURINE, AND gamma-AMINOBUTYRIC ACID IN CONSTANT RANGE WITH COMPOSITION ORGANIZATION AND FORMULATION RATIO OF MEDIUM IN CULTIVATING GANODERMA LUCIDUM KARST, AND BRACKET FUNGUS OF THE GENUS FOMES

摘要

PROBLEM TO BE SOLVED: To provide a method for cultivating Ganoderma lucidum Karst. and bracket fungus of the genus fomes by controlling the content of amino acids, taurine andγ-aminobutyric acid in addition to protein polysaccharides. SOLUTION: The bracket fungus of the genus fomes grown with uptake of amino acids is obtained by selecting a material containing plenty of amino acids in a culture medium and growing the same. In the growing process, the bracket fungus of the genus fomes producesγ-aminobutyric acid from glutamic acid and , cysteine and taurine from cystine. It is found that different data are given when a method for analyzing amino acids is varied and a part of the amino acids is changed to peptides. It is also found that forms depend on cultivation circumstances and the contents of the amino acids are increased when cultured in a branch form or an antler form rather than in an umbrella form.
