Fig. 4From: Application of the human estrogen receptor within a synthetic transcription factor in Trichoderma reeseiXylanolytic activities in absence and presence of 17β-estradiol. The Xyr1-deficient strain Xyr1′(81), the Xyr1 overexpression strain TX(WT), and the SynX-bearing strain TXYE were cultivated on xylan plates containing indicated concentrations of 17β-estradiol (Estr.) or only the solvent DMSO as control. Pictures were taken after 72 h of cultivation. Pictures are to scale and can be compared to the scale barBack to article page
