Uptake of Mannitol by Transgenic Saccharomyces Cells.

Yeast cells were grown to the early logarithmic phase in minimal medium supplemented with either 2% glucose or 2% mannitol. During uptake, the mannitol concentration was 500 μM and the external pH was 4.5. Squares represent uptake by cells transformed with AgMaT1, and circles represent mannitol uptake by control cells transformed with the plasmid YEP112A1XE. The results are means ±sd of three independent experiments (four replicates per experiment).
