The production of a milk-clotting enzyme by Aspergillus versicolor in 19 different culture media was investigated. Considerable milk-clotting activity was achieved by supplying corn steep liquor with either glucose of maltose. Dephytinization of corn steep liquor had an adverse effect on the production of milk-clotting enzyme. The results indicated that complex organic compounds favoured the production of the enzyme. Precipitation with acetone or tannin was unsuitable, but ammonium sulphate and… CONTINUE READING
