Fig. 2From: Systematic optimization of gene expression of pentose phosphate pathway enhances ethanol production from a glucose/xylose mixed medium in a recombinant Saccharomyces cerevisiaeFermentation profiles of strains expressing XI and overexpressing two PPP genes. Cells were initially inoculated at OD600 = 3 and cultivated in medium containing 85 g/L glucose and 35 g/L xylose for 72 h at 36 °C. a YK222 (KmTAL1opt-ScTKL1), b YK193 (KmRKI1opt-ScTKL1), c YK223 (KmRPE1opt-ScTKL1). Blue line: glucose, Red line: xylose, Green line: xylitol, Purple line: glycerol, Light blue line: acetate, Orange line: ethanol. Each data point is an average of triplicate culturesBack to article page
