Table 1.

Biomass yields vary by species, morphology and medium.

The biomass yield (dried cell weight) of the yeast form of the pathogens, C. albicans and C. neoformans, were compared with that of the non-pathogenic obligate yeast, S. cerevisiae, by growing cells for 18 h in YPD pH 5.6 at 30 °C. Yields from the yeast and hyphal forms of C. albicans were obtained from growth in MSM pH 4.5 at 30 °C for 24 h (yeast) or pH 6.8 at 37 °C for 8 h (hyphae). Yields for C. albicans and A. fumigatus hyphal filaments were obtained by growing cells in Complete Medium pH 6.5 at 37 °C for 18 h. SD = standard deviation, n = 3.
