Abstract
Electron microscopic observations of mitotically-dividing blastospores of the imperfect fungus, Aureobasidium pullulans have revealed a variety of polyphosphate inclusion bodies in association with chromatin at varying stages of nuclear mitotic division. The bodies varied in size up to a diameter of nearly 0.5μm. Only occasional observations of polyphosphate bodies were otherwise made. When found, they were in the vacuolar system included in small cytoplasmic pockets.
