Assay of residual Al in the culture after incubation with transgenic yeast in the presence of 0.2 mM Al3+ (a) or 2 mM Al3+ (b). Uninoculated media was shaken and used as a negative control. The residual Al in the negative control was designated as 100%. All values are the means of three replicates. Asterisks represent significant differences when compared with the controls (P < 0.05)
