Sugar utilization and xylose isomerase transcription by wild type grown in xylose with and without glucose. a The amount of xylose (squares) remaining in the culture supernatant when grown in the absence of glucose. b Amount of glucose (circles), xylose, and xylitol (triangles) present in the culture supernatant when grown in the presence of both sugars. Error bars represent standard deviation from triplicates. c Cultures were batched in glucose and xylose then re-fed glucose after the first xylose uptake period as indicated by the asterisk. Error bars represent standard deviation from three fermentations
