[Occurrence of an extracellular beta-(1 to 3)-glucanase from Botrytis cinerea].
Like other fungi, Botrytis cinera produces an exocellular beta-(1 leads to 3)-glucanase. This constitutive enzyme is produced only when Botrytis is cultivated in a glucose depleted medium. The enzyme is precipitated by ammonium sulfate from 20 to 80% saturation. Maximum activity is at pH between 5 and 6 and temperature between 40 and 50 degrees C; stability is good up to 30 degrees C. This enzyme cannot be applied to the treatment of wines containing Botrytis glucan.
