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 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 …
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…

The lignocellulosic biomass from plant-derived waste can be converted into second-generation biofuels in a process that requires the deconstruction of this material into smaller and simpler molecules. The fungus Trichoderma reesei produces enzymes, such as cellulases, that are involved in the hydrolysis of the lignocellulosic biomass; however, due to the high costs of production, optimiza…
One of the challenges to the economic viability of ethanol produced from lignocellulosic biomass (2G ethanol) is in the fermentation stage. Saccharomyces cerevisiae, is widely used in Brazilian plants for the production of 1G ethanol. However, for this yeast be employed with success in producing large volume of 2G ethanol is necessary to expand the use of different carbon sources, includi…
The filamentous fungus Trichoderma reesei is known for its high capacity in secrete cellulolytic enzymes that act in the hydrolysis of cellulose, which is a key point in the production of bioethanol. The gene expression of fungal cellulases is finely controlled at transcriptional level according to the available carbon source in the culture medium. Despite the numerous studies on the regu…

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…
The filamentous fungus Trichoderma reesei is known for its efficiency in producing and secreting holocellulases, enzymes used in the biofuel industry, such as bioethanol. A recent study in our laboratory identified a putative transcription factor (Tr_103275), homologous to the protein Azf1 of Saccharomyces cerevisiae, which is potentially involved in the regulation of plant biomass degrad…
