Tracking the roots of cellulase hyperproduction by the fungus Trichoderma reesei using massively parallel DNA sequencing.
Trichoderma reesei (teleomorph Hypocrea jecorina) is the main industrial source of cellulases and hemicellulases harnessed for the hydrolysis of biomass to simple sugars, which can then be converted to biofuels such as ethanol and other chemicals. The highly productive strains in use today were generated by classical mutagenesis. To learn how cellulase production was improved by these technique...
متن کاملProduction of Industrial Enzymes in Trichoderma reesei
The mesophilic filamentous fungus Trichoderma reesei (teleomorph Hypocrea jecorina) has become a major cell factory in the enzyme industry, and the benchmark organism for production of cellulases, especially for biomass conversion. The strain was originally isolated during the second World War from US Army tent canvas in the Solomon Islands and initially identified as Trichoderma viride. The is...
متن کاملAchieving efficient protein expression in Trichoderma reesei by using strong constitutive promoters
BACKGROUNDS The fungus Trichoderma reesei is an important workhorse for expression of homologous or heterologous genes, and the inducible cbh1 promoter is generally used. However, constitutive expression is more preferable in some cases than inducible expression that leads to production of unwanted cellulase components. In this work, constitutive promoters of T. reesei were screened and success...
متن کاملAdsorption Characteristics of Cellulases from a Constitutive of Trichoderma reesei Mutant
The adsorption parameter, A,, (maximum protein adsorbed/g substrate) and KA (adsorption equilibrium constant) of Trichoderma reesei C-5 cellulases were 58.8 mg protein/g cellulose and 11.6 x 104 Z/m01 respectively. The activation energies for the adsorption rate constants of cellobiobydrolases and endoglucanases of C-5 were 30% and 11% lower respectively than that in the parent T. reesei QM9414...
متن کاملInduction of cellulolytic enzymes in Trichoderma reesei by sophorose.
Sophorose (2-O-beta-glucopyranosyl-D-glucose) induces carboxymethyl cellulase in Trichoderma reesei QM6a mycelium with 1.5 to 2 h. The induction response to sophorose concentration, although complicated by the metabolism of sophorose, shows saturation kinetics. Most of the cellulase appears after most of the sophorose has been taken up, but the presence of an inducer is required to maintain cel...
