XynA production in a ∆ctsR deletion strain. A XynA production by the BWB09/pCS58 wild type (wt) and SGB03/pCS58 ∆ctsR deletion strains during growth. Averages and standard deviations of 3 independent experiments are shown. B Coomassie staining of proteins precipitated from 10 h supernatant samples. Molecular weights are indicated on the left side. The asterisk marks the XynA protein bands in the supernatant samples. Bars on the left represent protein densitometry quantification of the Coomassie-stained gel of three replicates
