Table 1 Comparison of specific aerobic growth rates in YPX50 medium for strains harboring XIs

From: Molecular evolutionary engineering of xylose isomerase to improve its catalytic activity and performance of micro-aerobic glucose/xylose co-fermentation in Saccharomyces cerevisiae

Strain Name Origin Specific growth rates (µ) (h−1)
SS36 a a NA
SS37 BcXI Burkholderia cenocepacia J2315 NA
SS38 PrXI Prevotella aff. ruminicola TC2-24 0.39 ± 0.05
SS39 RfXI Ruminococcus flavefaciens 17 0.58 ± 0.03
SS40 OspXI Orpinomyces sp. ukk1 0.71 ± 0.07
SS41 PspXI Piromyces sp. E2 0.51 ± 0.10
SS42 LpXI Lachnoclostridium phytofermentans ISDg 0.62 ± 0.09
SS43 RcXI Ruminiclostridium cellulolyticum H10 NA
SS44 SrXI Streptomyces rubiginosus 0.03 ± 0.01
  1. The mean specific growth rate with standard deviations of biological triplicates are shown
  2. NA: aerobic growth in YPX50 medium was very poor or showed no growth
  3. aSS36 was a control strain carrying a plasmid vector lacking any XI genes
