During alcoholic fermentation to produce fuel ethanol, the use of acid treatment to combat bacterial contamination is a very common practice in Brazilian units. An aqueous solution of sulfuric acid at a pH ranging from 2.0-2.5 is used for a period of two hours, causing a significant reduction in the number of bacterial cells and promoting the deflocculation of the yeast caused by both bac…
Antimicrobial compounds extracted from natural sources have great potential in the control of bacterial and fungal contamination in the food industry. They are found in herbs, spices, fruits, seeds, leaves and animal shells, constituting a new, safe and environmentally recommended option, since that wastes can be utilized as antimicrobial sources. In the alcoholic fermentation for fuel et…
Brazil is the greatest ethanol exporter and the second world producer. The fermentation process has some peculiarities as the fact that it does not occur in aseptic conditions. Therefore, contaminations by wild (native) yeasts or bacteria may result in lower fermentative efficiency. One of the most important yeast contaminant of the fermentation is Dekkera bruxellensis, which displays eth…

Aiming for an effective alternative that is sustainable for the environment, healthy andclean for the consumer, and presents good economic results, this project presents a proposalto investigate the application of bioparticles from sugarcane bagasse as a plant-based antimicrobialagent in the control and decontamination of the ethanolic fermentation process.Due to the complex structure of …
As an alternative to fossil fuels, the production of ethanol derived from sugar cane, through ethanolic fermentation, is of paramount economic and environmental importance. Despite the environmental advantages of using ethanol, bacterial contamination during fermentation, especially lactic acid bacteria, compromises the efficiency of the fermentation process. The use of sulfuric acid in d…

During the fermentation process for fuel ethanol production, bacterial contamination - especially by lactic acid bacteria- compromises the efficiency of the process. The use of sulfuric acid, while effective in reducing bacterial counts, has environmental impacts and high costs. Hydrochloric acid has been proposed as an alternative, though its effects on yeast are not well understood. Wea…
