Abstract:
The influence of different fructose concentrations (5, 3, 1 and 0 g/l) was tested on Germ Tube (GT) production by Candida albicans strain AS3P, using a Minimal Synthetic Medium (MSM) without (NH4)2SO4. The results obtained showed good GT production in the presence of all the different fructose concentrations and in the absence of any nitrogen source. The greatest GT production was obtained with 3 g/l of fructose vs 1 g/l of glucose, after 4 hr of incubation. On the other hand fructose consumption was lower than that of glucose at all concentrations over the 4 hour period. The data obtained may suggest that fructose is metabolized in a different way from glucose for GT production by C. albicans.
