The nature of mycelial lipolytic enzymes in filamentous fungi
... was first reported by Dawson in 1958 [6]. It is of course recognised that the phospholipase B type of activity could be due to the action of phospholipase A1 and highly active lysophospholipase. No evidence for the presence of phospholipase A2 was found associated with any of the organism examined. ...
