在24种不同培养基中研究了构巢曲霉培养物在自溶开始时（菌丝体的最大干重）和自溶期间的几丁质分解活性。在生长过程中，几丁质分解活性仅由培养基中存在的抗坏血酸或胶体几丁质诱导。在自溶过程中，在所有条件下观察到几丁质降解活性随着孵育时间的增加而增加，并且检测到β-N-乙酰葡糖胺酶和内切几丁质酶的合成。这些酶在A.建立了nidulans自溶。
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.
