|
For the purpose of utilizing cellulose resources by cellulolytic enzymes of Roseofomes subflexibilis, it’s cultural conditions for the production of cellulolytic enzymes in synthetic media were investigated. The results obtained were summarized as follows : The optimum temperature and pH for the enzyme production were $30^{\circ}C$ and pH 4.0, respectively. Among the carbon sources, glucose was good for the production of cellulase. The optimum concentration of saccharose as 1.2%. As a organic nitrogen source, yeast extract was good for the mycelial growth. The optimum concentration of yeast extract as 1.5%. As a inorganic nitrogen source, $NH_{4}H_{2}PO_{4}$ was good for the mycelial growth. The optimum concentration of $NH_{4}H_{2}PO_{4}$ were 1.1%. The mineral salt of $Al_{2}(SO_{4})_{3}$ was effective and the optimum concentration was 0.1 M.
