Furfur. At the same time, selected the culture supernatant. Used the whole-fat-cow"s-milk plate method, the Folin-phenol method and the QuantiCleave proteinase Assay Kit to test the proteinase activity of mycelial phase and yeast phase of M. furfur. The effect of temperature and pH on this assay was also evaluated.Result:①The whole-fat-cow"s-milk plate method: Seven days after inoculation, the proteinase activity of the mycelial phase supernatant (12.5 ± 1.2mm) is higher than that of the yeast phase (9.25±0.71mm)(p.05); With the passage of the inoculation time, the proteinase activity of the mycelial phase is rising; the temperature has no obvious effect on the proteinase
