Comparison of glucosidase and growth inhibition activities of WmKT. Growth inhibition (histograms) was measured as described in Material and Methods, and the glucosidase activity expressed in µM of p-nitrophenol released per microgram of WmKT (curve) was determined using p-nitrophenyl-β-D-glucopyranoside. Both assays were performed at pH 4.6 (A) and pH 6.0 (B). (C) Results obtained using WmKT incubated at pH 6.0 prior to acidification to pH 4.6. Means and standard deviations were calculated from three independent experiments.
