Fig. 2From: Screening and evolution of a novel protist xylose isomerase from the termite Reticulitermes speratus for efficient xylose fermentation in Saccharomyces cerevisiae Xylose isomerase activities of the novel XI genes and Piromyces sp. E2 XI gene. Each gene was expressed in S. cerevisiae PP600 strain and xylose isomerase activity in the cell extract of each recombinant yeast strain was determined as described in "Methods". Error bars represent standard deviations of 4 independent experimentsBack to article page
