Chitinolytic activity in filtrates of Aspergillus nidulans cultures was studied at the start of the autolysis (maximum dry weight of mycelium) and during autolysis in 24 different media. During the growth the chitinolytic activity was induced only by the presence of ascorbic acid or colloidal chitin in the medium. During autolysis an increasing chitinolytic activity was observed with the incubation time in all the conditions, and synthesis of a β ‐ N ‐acetylgucosaminidase and endochitinase was detected. The possible induction of these enzymes during A. nidulans autolysis is established.
