Figure 3From: Isolation of xylose isomerases by sequence- and function-based screening from a soil metagenomic libraryAerobic growth of E. coli recombinant strains carrying pRSETB-Xym1 (filled triangle), pRSETB-Xym2 (filled circle), pRSETB-XIPiromyces (filled square), or the empty plasmid pRSETB (filled diamond). All strains were cultivated at 37°C in SM3 media supplemented with 30 g/L xylose.Back to article page
