ETHANOL PRODUCTION THROUGH ENZYMATIC PROCESSES

Greetings and welcome dear readers of this prestigious platform, the topic that concerns us in this opportunity is of a scientific nature under a flexible modality that allows us to understand the enzymatic functioning as a mechanism for the production of ethanol as a second generation fuel.

In this sense, we will rely on a set of investigations that are being carried out from the laboratories of Chemical Analysis of the University of Campinas in Brazil, where it was possible to detect a chemical molecule from the Amazonian fungus Trichoderma harzianum with characteristics and enzymatic properties that allow current on different sugars that constitute the plant biomass essential in obtaining renewable fuels in order to combat the scenarios of pollution and environmental degradation.

Undoubtedly the discovery gives a light at the end of the road, since under the studies carried out it allows to generate a greater use of plant residues produced in different agricultural processes, among which stand out the residues from sugar cane and corn, indispensable in the production of biofuels.

The most interesting aspect of the process is that it initiates the elaboration of low-cost enzyme cocktails, which will allow obtaining the bio-product so necessary at an energetic level. We must remember that an enzyme is a substance that catalyzes different chemical reactions, generating interrelationships between substrates and the enzyme, which produces a decrease in the activation energy of the process and consequently a growth in the speed of the same.

So researchers have relied on this behavior to evaluate the fungal lineage using a set of scientific tools, associated with the analysis of genetic, protein and metabolic variations in fungi, leading them to consider their critical roles in other substrates such as plant cellulose.

As a remarkable result of this arduous work, the researchers have managed to highlight that fungi of the Trichoderma genus, exhibit great potential in the manufacture of active enzymes that attack carbohydrates, where they have been able to isolate compounds associated with the family glycoside hydrolases indispensable in the biomass of products already mentioned above.

In the opinion of Leal Motta, active researcher of the project:

So the effectiveness of the product is determined with the ability to prepare different enzyme cocktails that attack the lateral membrane of hemi-cellulose and consequently the second generation ethanol can be degraded and produced more easily.

In this sense, we will be attentive to the scientific advances of this research with important projections at an energetic and environmental level.
