قارچ Trichoderma reesei یک میکروارگانیسم سلولولتیک می باشد که به منظور تولید آنزیمهای سلولازی تحت شرایط تخمیر غوطه ور مورد استفاده قرار می گیرد. در این تحقیق، بعد از چندین مرحله جهش با موتاژن شیمیایی NTG و موتاژن فیزیکی uv، از مجموع 6500 کلونی بررسی شده از این قارچ، یک سویه سلولولیتیک کارآمد به نام 2: 6A به دست آمد که حداکثر میزان تولید آنزیم اگزوکلوکاناز توسط این سویه در روز چهارم U/ml 26/1...
BACKGROUND Although the biocatalytic conversion of cellulosic biomass could replace fossil oil for the production of various compounds, it is often not economically viable due to the high costs of cellulolytic enzymes. One possibility to reduce costs is consolidated bioprocessing (CBP), integrating cellulase production, hydrolysis of cellulose, and the fermentation of the released sugars to the...
The filamentous fungus Trichoderma reesei is a widely used strain for cellulolytic enzyme production. A hypercellulolytic T. reesei variant SN1 was identified in this study and found to be different from the well-known cellulase producers QM9414 and RUT-C30. The cellulose-degrading enzymes of T. reesei SN1 show higher endoglucanase (EG) activity but lower β-glucosidase (BGL) activity than those...
BACKGROUND The presence of low complexity and repeated regions in genomes often results in difficulties to assemble sequencing data into full chromosomes. However, the availability of full genome scaffolds is essential to several investigations, regarding for instance the evolution of entire clades, the analysis of chromosome rearrangements, and is pivotal to sexual crossing studies. In non-con...
Trichoderma reesei is a high-yield producer of cellulase for applications in lignocellulosic biomass conversion, but its production requires induction. A mixture glucose and β-disaccharide has been demonstrated to achieve high-level production. However, as inducers, β-disaccharides are prone be hydrolyzed by β-glucosidase (BGL) during fermentation, therefore need supplemented through feeding ov...
