title: Liberation of protoplasts from the yeast-like form of Paracoccidioides brasiliensis by enzymatic treatment.
abstract: Spherical and osmotically sensitive protoplasts were released from cultures of the yeast-like form of Paracoccidioides basilienisis strain IVIC Pb9 through the action of a mixture of crude enzyme preparations: alpha and beta-glucanases and chitinase, obtained from culture filtrates of Cladosporium resinae, Basidiomycete QM 806 and Streptomyces sp respectively. The highest efficiency of protoplast liberation was achieved when each crude enzyme preparation was used at 1 mg/ml.
