PirXI V270A–A273G improves growth of S. cerevisiae strain DS75543 on xylose. The orange and green lines represent growth on xylose (20 g l−1) of yeast expressing the mutant and the wild-type PirXI, respectively. a, b Growth in 96-well plate with continuous measurement of optical density. Each line represents an individual clone selected from a transformation plate. c Growth in triplicate in batch culture with intermittent sampling and measurement of optical densities
