Fig. 9From: Tailoring the expression of Xyr1 leads to efficient production of lignocellulolytic enzymes in Trichoderma reesei for improved saccharification of corncob residuesSchematic summary showing the proposed model for the dosage regulation of xyr1 in T. reesei. A Compared to the strong xyr1 overexpression with the cbh1/cdna1 promoter, the moderate xyr1 overexpression with the egl2 promoter can result in more open chromatin and stronger expression of cellulase gene, thus significantly enhancing cellulase production. B The lignocellulolytic enzyme production and saccharification efficiency were significantly improved in T. reesei QE2X, because of the high expression of cellulase and accessory proteinsBack to article page
