Abstract
Blastospores of A. pullulans germinate within 4 h post-inoculation on malt extract medium. Small amounts of mucilaginous material are present on the cell surface at this time. By 10 h post-inculation further elongation of the germ tube occurs, the mucilaginous material blankets most of the hyphae, and newly produced blastospores appear. Spicules connecting blastospores to parent hyphae develop after spore maturation. A truncate base of the blastospores appears as a flattened projection at one or both ends. It is derived from part of the spicule, or connecting isthmus between spore and hypha. Some blastospores develop into swollen cells, swollen septate cells, or chlamydospores rather than germinating. The former 2 cell types produce new blastospores, while the latter becomes a resistant cell type characterized by a thick wall and large amounts of melanin deposits.
