Figure 4From: Isolation of xylose isomerases by sequence- and function-based screening from a soil metagenomic libraryAerobic growth of S. cerevisiae recombinant strains carrying p426TEF-Xym1 (filled triangle), p426TEF-Xym2 (filled circle), p426TEF-XiPiromyces (filled square) or the empty plasmid p426TEF (filled diamond). All strains were cultivated at 30°C in mineral media supplemented with 50 g/L xylose.Back to article page
