Abstract

Cryptococcus neoformans exhibited diphasic growth when grown under limitedaeration. First, it grew exponentially, but at OD 1, the concentration of dissolved oxygen in culture decreased to 1 mg l(-1) and a second phase of slow growth was started. This phase was characterized by a shift of budding from S to G(2), a sharp decrease in budding index and a sharp increase in the proportion of unbudded G2 cells to 80%. Thus, a deficit in oxygen was demonstrated to delay the timing of budding, prolong the G(2) phase and causeaccumulation of cells after DNA synthesis, but before commitment to budding.
