Effect of the gpdA p ::xlnR genetic background on native xylanase activity. Time course analysis of the extracellular xylanase activities in gpdAp::xlnR strains (AR66 and AR67) and controls (wild type biA1 and the nutritional arginine prototrophic control AR70). AR66, AR67 and AR70 are isogenic strains bearing respectively one copy of pILJ16_gpdAp::xlnR or pILJ16 integrated at the argB locus. The mycelia were grown under non-repressing, non-inducing conditions (0.1% w/v fructose) before being transferred to inducing conditions (1% w/v xylose), and samples were collected at the time points indicated. Values (means ± standard deviation (SD)) are expressed as percentages and referred to that of the AR70 strain at 24 hours. For each strain, two independent experiments with two independent cultures were carried out.
