1. Fungi contains a enzyme which clarifies the fruits juice. 2. The enzyme was extracted by water, but not precipitated by ammonium sulfate perfectly. 3. The optimum temperature were 40_??_50° and the optimum pH for the enzyme 4.5_??_5.5. 4. The enzyme decomposed the pectin or pectic acid solutions directly, and remarkable and rapid decrease of the viscosity of the solutions were observed. But litte or no increase of the reducing power and the acidity were observed. 5. The reaction of the enzyme was accelerated by ammonium sulfate and some other salts. 6. The-enzyme from fungi was considered as depolymerase.
