The fungus Trichoderma reesei is recognized as an industrial producer of cellulases. These enzymes move a market that grows every year and in the order of millions of dollars. The major cellulase genes are regulated in a coordinated manner according to available carbon source. Expression of these genes can be induced by cellulose and other substances (eg, cellobiose, sophorose and lactose…
Several Trichoderma spp. are well known for their ability to: i) act as important biocontrol agents against phytopathogenic fungi;ii) function as biofertilizers; iii) increase the tolerance of plants to biotic and abiotic stresses; and iv) induce plant defenseresponses via the production and secretion of elicitor molecules. In this study, we analyzed the gene-regulation effects ofTrichode…
Brazil is one of the countries with the greater diversity in terms of lignocellulosic biomass. The lignocellulolytic enzymes production by filamentous fungi has been the constant subject of study, mainly because such enzymes are of crucial importance in the processes of generation biofuels from plant biomass. However, no micro-organism considered to be highly effective for the hydrolysis …

The fungus T. reesei is a prominent industrial producer of cellulases, enzymes that hydrolyze crystalline cellulose into glucose. The expression of cellulase genes is coordinately regulated according to the available carbon source, but the molecular mechanisms that regulate this expression are still poorly understood. So far, 12 transcription factors and proteins involved in transcription…
Whereas the production of second-generation ethanol (2G) has not yet been as consolidated as for 1G ethanol, there is much to be explored in order to optimize this process. Among the most studied possibilities, the improvement of the fermentation step may be highlighted. Glucose and xylose are the two most abundant sugars in the lignocellulosic biomass, so it is crucial for them to be eff…
Lignocellulolytic enzymes are of fundamental importance in biofuel generation processes from plant biomass. The filamentous fungus Trichoderma reesei is a major producer of holocellulases, having one of the most intelligent cellulolytic systems. The gene expression of these enzymes is finely controlled by several transcription factors, which are used in genetic improvement strategies for …
The fungus Trichoderma reesei is capable of producing and expressing several cellulases and hemicellulases involved in the degradation of lignocellulosic biomass, however, to make the saccharification process and consequently to obtain ethanol economically viable, it is necessary to optimize the production of these enzymes. The filamentous fungal transporters are important for regulating …
Plant biomass is the most abundant natural material present on Earth. It is composed of polysaccharides, with cellulose as the main component. Several microorganisms being studied with potential biotechnological use to degrade plant matter. The fungus Trichoderma reesei is known for its high capacity to secrete cellulolytic enzymes that act by degrading the cellulose polymer into glucose …
With the increase in demand for ethanol and the production of high added value chemicals, the use of lignocellulosic biomass for these purposes has been widely studied. The degradation of this biomass is a process that requires a cocktail of enzymes, called holocellulases, which act cooperatively. The filamentous fungus Trichoderma reesei has a high capacity to produce and secrete holocel…

The filamentous fungus Trichoderma reesei can produce high amounts of cellulases and hemicellulases that convert the polysaccharides in lignocellulosic biomass into fermentable sugars. However, to make second-generation ethanol economically viable, optimizing the production of these enzymes is necessary. Sugar transporters in T. reesei are essential for the regulation of cellulases and he…
Trichoderma reesei is a saprophytic fungus widely known for its ability to produce large amounts of cellulases. These enzymes are critical for the production of high-value bioproducts from lignocellulosic biomass (LCB), such as ethanol. The cellulolytic system of T. reesei is finely regulated at the transcriptional level, and several transcription factors (TFs) coordinate the expression o…
In the second-generation (2G) ethanol production process, the enzymatic hydrolysis of lignocellulosic biomass releases a mixture of sugars, including hexoses (e.g., glucose), pentoses (e.g., xylose), and cellodextrins (e.g., cellobiose). Over the fermentation stage, the transport of these sugars into the yeast cell is the first and critical step to enable the microbial production of ethan…
One of the major challenges of biotechnology is the development of biological processes that reduce the negative impacts on the environment caused by the burning of fossil fuels. In this context, biofuels have received attention in recent decades. Trichoderma reesei and Aspergillus niger are among the main producers of lignocellulolytic enzymes, which are used in the conversion of lignoce…
