Abstract
Protoplasts of Y-cells and partially converted M-cells from several human isolates of Paracoccidioides brasiliensis were obtained with a combined enzyme system containing Novozym 234 and a chitinase. A laboratory made extract from Trichoderma harzianum CBS-345-33 supplemented with chitinase induced the release of protoplasts from partially converted M-cells but not from established Y-cells. A similar yield of protoplasts (1-2 x 10(5) ml-1 after 16 h) was produced by using either enzymatic system. Protoplasts regenerated on nutrient gelatin at 23 degrees C at a frequency of 0.1%.
