Popis: A new strain of Penicillium cyclopium was found on mouldy Grenoble walnuts. From the culture filtrate, two new extracellular lipases (A- and B-lipase) were isolated and characterized. The mycelium contained one of the two forms of lipase (B-lipase). The specificity of the cell-bound lipase linked to the mycelium was then studied. The enzyme was specific to shortchain homogeneous triacylglycerols; it preferred to attack the o-position rather than the p-position, and showed stereospecificity on the sn-1 position.
