Resumo: | Beer is a beverage made up of water, malt, hops and yeast. Yeast is the main transforming agent, converting sugars into ethanol, CO2 and a series of compounds providing flavor and aroma. Saccharomyces yeasts stand out as the most used by the industry. With the growing number of beer consumers and the great diversity of flavors, the number of breweries is also increasing. The objective of this research was to evaluate the biotechnological potential of non-Saccharomyces yeasts kept in collections. The biotechnological potential to be used in the industry was evaluated. Biochemical differentiation of strains into ALE and LAGER, ethanol tolerance and yeast flocculation potential were performed. The results obtained showed that the yeasts presented a potential to be applied in fermentation processes. All yeasts used in the biochemical differentiation tests showed results that allow classifying them as LAGER type yeasts. In the flocculation test, all yeasts were found to be industrial yeasts according to the classification criteria of the American Society of Brewing Chemistry. In the evaluation of ethanol tolerance at concentrations of 10%, 15% and 20%, only the yeast used in the control showed tolerance to 15% ethanol, the yeast Saccharomyces cerevisiae obtained from the culture collection showed tolerance to 10% ethanol, and the others did not. showed tolerance to ethanol at the concentrations used. The study presented promising results suggesting that yeasts can be used in fermentation processes, being necessary to carry out further investigations to certify the real potential of these yeasts. |

La levadura es el principal agente transformador, convirtiendo los azúcares en etanol, CO2 y una serie de compuestos que aportan sabor y aroma. Las levaduras Saccharomyces se destacan como las más utilizadas por la industria. Con el creciente número de consumidores de cerveza y la gran diversidad de sabores, el número de cervecerías también está aumentando. El objetivo de esta investigación fue evaluar el potencial biotecnológico de levaduras no Saccharomyces conservadas en colecciones. Se evaluó el potencial biotecnológico a ser utilizado en la industria. Se realizó la diferenciación bioquímica de las cepas en ALE y LAGER, la tolerancia al etanol y el potencial de floculación de la levadura. Los resultados obtenidos mostraron que las levaduras presentaron potencial para ser aplicadas en procesos de fermentación. Todas las levaduras utilizadas en los ensayos de diferenciación bioquímica arrojaron resultados que permiten clasificarlas como levaduras tipo LAGER. En la prueba de floculación, todas las levaduras resultaron ser levaduras industriales según los criterios de clasificación de la American Society of Brewing Chemistry. En la evaluación de la tolerancia al etanol a concentraciones del 10%, 15% y 20%, solo la levadura utilizada en el control mostró tolerancia al etanol al 15%, la levadura Saccharomyces cerevisiae obtenida de la colección de cultivos mostró tolerancia al etanol al 10%, y la otros no mostraron tolerancia al etanol a las concentraciones utilizadas. El estudio presentó resultados prometedores que sugieren que las levaduras pueden ser utilizadas en procesos de fermentación, siendo necesario realizar más investigaciones para certificar el potencial real de estas levaduras.A cerveja é uma bebida constituída por água, malte, lúpulo e leveduras. A levedura é o principal agente transformador, convertendo os açúcares em etanol, CO2 e uma série de compostos conferindo sabor e aroma. Destaca-se as leveduras Saccharomyces como as mais utilizadas pela indústria. Com o crescente número de consumidores de cervejas e a grande diversidade de sabores, o número de cervejarias também vêm aumentando. O objetivo desta pesquisa foi avaliar o potencial biotecnológico de leveduras não-Saccharomyces mantidas em coleção. Avaliou-se a potencialidade biotecnológica para serem utilizadas na indústria. Realizou-se a diferenciação bioquímica das cepas em ALE e LAGER, a tolerância a etanol e o potencial de floculação das leveduras. Os resultados obtidos demonstraram que as leveduras apresentaram um potencial para serem aplicadas em processos fermentativos. Todas as leveduras utilizadas nos testes de diferenciação bioquímica apresentaram resultados que permitem classificá-las como leveduras do tipo LAGER. No teste de floculação todas as leveduras se mostraram como leveduras com característica industrial segundo o critério de classificação da American Society of Brewing Chemistry. Na avaliação de tolerância ao etanol nas concentrações de 10%, 15% e 20% apenas a levedura usada no controle demonstrou tolerância ao etanol 15%, a levedura Saccharomyces cerevisiae obtida na coleção de cultura demonstrou tolerância ao etanol 10%, e as demais não apresentaram tolerância ao etanol nas concentrações utilizadas. O estudo apresentou resultados promissores sugerindo que as leveduras podem ser utilizadas em processos fermentativos, sendo necessária a realização de maiores investigações para certificar o real potencial destas leveduras.Research, Society and Development2022-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3275410.33448/rsd-v11i10.32754Research, Society and Development; Vol. 11 No. 10; e322111032754Research, Society and Development; Vol. 11 Núm. 10; e322111032754Research, Society and Development; v. 11 n. 10; e3221110327542525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/32754/27821Copyright (c) 2022 Pérsio Alexandre da Silva; Ninive Bezerra Florêncio; Gleyka Daisa de Melo Santos; Erik Jonne Vieira de Melo; Norma Buarque de Gusmãohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Pérsio Alexandre daFlorêncio, Ninive BezerraSantos, Gleyka Daisa de MeloMelo, Erik Jonne Vieira de Gusmão, Norma Buarque de2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/32754Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:38.465975Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
