  1. The enzymatic activity of XylB that catalyzes the conversion of d-xylose into d-xylono-γ-lactone was assayed in five strains including: TMB4511 (XylB, XylC), TMB4530 (XylB, Cc XylD, XylX, XylA), TMB4569 (XylB, Bc XylD, xylX, xylA), TMB4570 (XylB, Ec YjhG_Ec, XylX, XylA) and TMB4571 (XylB, El XylD_El, xylX, xylA). As a control strain, TMB4515 that contains only the lower part of the pathway including Cc XylD, XylX and XylA was used
