Increased Production and Activity of Cellulase Enzyme of Trichoderma reesei by Using Gibberellin Hormone
Cellulolytic complex are enzymes capable of hydrolyzing cellulose. Due to rapid growth in population and industrialization, most countries are required to produce more fuel. Production of bioethanol from lignocellulosic biomass is very challenging due to environmental pollution by fossil fuels. Cellulases play a significant role in biotechnological processes. The cost of production of cellulase...
متن کاملEnhanced Expression of Endochitinase in Trichoderma harzianum with the cbh1 Promoter of Trichoderma reesei.
Production of extracellular endochitinase could be increased 5-fold in the mycoparasite fungus Trichoderma harzianum by using the cellulase promoter cbh1 of Trichoderma reesei, whereas the total endochitinase activity increased 10-fold. The cbh1 promoter was not expressed on glucose and sucrose in T. harzianum and was induced by sophorose and on cellulase-inducing medium. The endogenous endochi...
متن کاملGenome Sequence and Annotation of Trichoderma parareesei, the Ancestor of the Cellulase Producer Trichoderma reesei
The filamentous fungus Trichoderma parareesei is the asexually reproducing ancestor of Trichoderma reesei, the holomorphic industrial producer of cellulase and hemicellulase. Here, we present the genome sequence of the T. parareesei type strain CBS 125925, which contains genes for 9,318 proteins.
متن کاملOptimization of Extracellular Cellulase Production by Trichoderma harzianum
ABSTRACT Background and Objectives: Cellulose is a major component of plant biomass, which can be converted into biofuels and valuable chemicals. The key step in utilization of this organic material is its hydrolysis into soluble sugars. This study evaluated cellulase production by Trichoderma harzianum under different pH values, temperatures and incubation...
متن کاملFingerprinting Trichoderma reesei hydrolases in a commercial cellulase preparation.
Polysaccharide degrading enzymes from commercial T. reesei broth have been subjected to "fingerprint" analysis by high-resolution 2-D gel electrophoresis. Forty-five spots from 11 x 25 cm Pharmacia gels have been analyzed by LC-MS/MS and the resulting peptide sequences were compared to existing databases. Understanding the roles and relationships of component enzymes from the T. reesei cellulas...
