Coordinately express hemicellulolytic enzymes in Kluyveromyces marxianus to improve the saccharification and ethanol production from corncobs

Biotechnology for Biofuels, 2021
Background Hemicellulose acts as one factor contributing to the recalcitrance of lignocellulose that prevents cellulases to degrade the cellulose efficiently even in low quantities.

Production of β-glucosidase on solid-state fermentation by Lichtheimia ramosa in agroindustrial residues: Characterization and catalytic properties of the enzymatic extract

Electronic Journal of Biotechnology, 2015
Background: β-Glucosidases catalyze the hydrolysis of cellobiose and cellodextrins, releasing glucose as the main product. This enzyme is used in the food, pharmaceutical, and biofuel industries.

Integrating 1G with 2G Bioethanol Production by Using Distillers’ Dried Grains with Solubles (DDGS) as the Feedstock for Lignocellulolytic Enzyme Production

Fermentation, 2022
First-generation (1G) bioethanol is one of the most used liquid biofuels in the transport industry. It is generated by using sugar- or starch-based feedstocks, while second-generation (2G) bioethanol is generated by using lignocellulosic feedstocks ...

Fungal Cellulase and Hemicellulase Prediction of Forage Digestibility

Journal of Dairy Science, 1975
An enzymatic procedure using Trichoderma viride carbohydrases, a fungal hemicellulase, and pepsin was developed to provide a laboratory method for predicting forage digestibility. The amount of forage dry matter solubilized by enzymes and incubation buffer was less than that in vivo or by in vitro fermentation by rumen microorganisms.

Metabolic engineering strategies for the improvement of cellulase production by Hypocrea jecorina

Biotechnology for Biofuels, 2009
Hypocrea jecorina (= Trichoderma reesei) is the main industrial source of cellulases and hemicellulases used to depolymerise plant biomass to simple sugars that are converted to chemical intermediates and biofuels, such as ethanol.

Comparative study of cellulolytic activity of three rumen fungi on different substrates [PDF]

Zbornik Matice Srpske za Prirodne Nauke, 2011
Anaerobic chytridiomycete fungi are found in the gastrointestinal tracts of many domesticated ruminant and nonruminant herbivores and of a wide variety of wild herbivorous mammals.

A Chrysoporthe cubensis enzyme cocktail produced from a low-cost carbon source with high biomass hydrolysis efficiency

Scientific Reports, 2017
Low cost and high efficiency cellulolytic cocktails can consolidate lignocellulosic ethanol technologies. Sugarcane bagasse (SCB) is a low cost agro-industrial residue, and its use as a carbon source can reduce the costs of fungi cultivation for enzyme ...

Bamboo fibre processing: insights into hemicellulase and cellulase substrate accessibility [PDF]

Biocatalysis and Biotransformation, 2011
A biological approach for degumming bamboo substrates has been assessed. The ability of various commercially available enzymes, including cellulase, xylanase, pectinase and mannanase, to hydrolyze bamboo powders was investigated. In addition, a commercial cellulase preparation was applied onto bamboo fi bre bundles obtained by natural retting.

Transcriptome analysis of Aspergillus niger grown on sugarcane bagasse

Biotechnology for Biofuels, 2011
Background Considering that the costs of cellulases and hemicellulases contribute substantially to the price of bioethanol, new studies aimed at understanding and improving cellulase efficiency and productivity are of paramount importance.

Transcription of Clostridium cellulovorans Cellulosomal Cellulase and Hemicellulase Genes [PDF]

Journal of Bacteriology, 2003
ABSTRACT Transcription of the cellulosomal cellulase/hemicellulase genes of Clostridium cellulovorans has been investigated by Northern blot, reverse transcriptase PCR (RT-PCR), primer extension, and S1 nuclease analysis.
