Quantification of the xylanase activity (a) and band intensity of Western blots (b) in media, cell wall, cytoplasmic and membrane fractions of P. thermoglucosidasius TM242 (without plasmid), and TM242 producing XynA1 or XynA1Δsp. Activity values are corrected for differences in OD₆₀₀ between the cultures, although it should be noted that those differences were small. All enzyme activity and band intensity data are relative to the values in the media fraction of TM242 producing XynA1, which was set at 100% (black bars; XynA1). The error bars show the standard errors of the mean of 6 independent biological replicates
