FIG. 1.

Effect of different pHs on growth of C. albicans. The parental strain CAF3-1 (open bars) or the Phr1⁻ mutant CAS8 (solid bars) were grown at 25°C in YPD containing 50 mM HEPES and buffered at the desired pH. The pH of the medium was monitored during growth and never changed by more than 0.1. Growth was monitored as increase in cell number.
