Production of Trichoderma reesei cellulases on glucose-containing media.
The filamentous fungus Trichoderma reesei was shown to secrete active cellobiohydrolase I and the endoglucanase I catalytic core domain into the culture medium when the fungus was grown on glucose-containing medium. The expression of the proteins was driven by the promoters of the elongation factor 1 alpha, tef1, and the unidentified gene for cDNA1. The cDNA1 promoter gave the best yields. The ...
متن کاملGenetic engineering of Trichoderma reesei cellulases and their production
Lignocellulosic biomass, which mainly consists of cellulose, hemicellulose and lignin, is the most abundant renewable source for production of biofuel and biorefinery products. The industrial use of plant biomass involves mechanical milling or chipping, followed by chemical or physicochemical pretreatment steps to make the material more susceptible to enzymatic hydrolysis. Thereby the cost of e...
متن کاملRole of four major cellulases in triggering of cellulase gene expression by cellulose in Trichoderma reesei.
The relative contributions of four major cellulases of Trichoderma reesei (1,4-beta-D-glucan cellobiohydrolase I [CBH I], CBH II, endo-1,4-beta-D-glucanase I [EG I], and EG II) to the generation of the cellulase inducer from cellulose were studied with isogenic strains in which the corresponding genes (cbh1, cbh2, egl1, and egl2) had been deleted by insertion of the Aspergillus nidulans amdS ma...
متن کاملTrichoderma reesei strains for production of cellulases for the textile industry
Trichoderma reesei is a biotechnically important filamentous fungus used commercially in enzyme production. T. reesei is also one of the best known cellulolytic organisms, producing readily and in large quantities a complete set of extracellular cellulases for the degradation of crystalline cellulose. In addition to T. reesei, a wide variety of other bacteria and fungi also produce cellulolytic...
متن کاملXpp1 regulates the expression of xylanases, but not of cellulases in Trichoderma reesei
BACKGROUND The ascomycete Trichoderma reesei is industrially used for the production of cellulases. During the production process xylanases are co-secreted, which uses energy and nutrients. Cellulases and xylanases share the same main regulators, which makes a knowledge-based strain design difficult. However, previously a cis-element in the promoter of the main xylanase-encoding gene was identi...
