Evaluation of synthetic capacities of GSH of engineered S. cerevisiae strains harbouring gshF gene under the control of four different promoters. Intracellular GSH amount was monitored after 24-h fermentation and measured every 12 h. The values are presented as the means, and the error bars show the SD (n = 3)
