This paper describes a method for separating and isolating plasma membranes from the septated fungus Podospora anserina. Plasma membranes were isolated from protoplasts (young cell plasma membranes) and mycelia (both young and aged cell plasma membranes). The procedure of fractionation consisted of a combination of differential and isopycnic centrifugations. Characterization of cellular membranes and enrichment of the fractions with plasmalemma were carried out by assays on enzymatic activities. A plasma membrane fraction was isolated in a buoyant density peak of 1.087 g/cm3, where three enzymatic activities bound to plasma membrane, adenylate cyclase, chitin synthase, and beta-glucan synthase at low affinity for UDP-Glc, peaked together. Good purity of this fraction was determined by the absence or the very low level of other enzymatic activities used as markers for intracellular membranes, i.e., succinate dehydrogenase, alpha-mannosidase, NADPH cytochrome c reductase, and beta-glucan synthase at high affinity for UDP-Glc activities.
