Efeito do 4-etilfenol sobre o crescimento e capacidade fermentativa da linhagem industrial de Saccharomyces cerevisiae PE-2
(Universidade Federal de São Carlos, 2019-02-26)
One of the main contaminating yeasts of ethanol production in Brazil is the species Dekkera bruxellensis. It is able to produce volatile phenolic compounds such as 4-vinylphenol and 4-ethylphenol from hydroxycinnamic acids ...
Produção de fenóis voláteis por isolados de Dekkera bruxellensis da fermentação etanólica e efeitos sobre uma linhagem industrial de Saccharomyces cerevisiae
(Universidade Federal de São Carlos, 2018-05-02)
One of the main contaminant yeast is Dekkera bruxellensis being known its ability to produce volatile phenolic compounds such as 4-vinylphenol (4-VP) and 4-ethylphenol (4-EP) from hydroxycinnamic acids through the activity ...
Efeito do ácido acético sobre o crescimento e fermentação da levedura Meyerozyma guilliermondii
(Universidade Federal de São Carlos, 2016-08-26)
The viability of technologies that make possible to use all available plant biomass, such as the production of lignocellulosic ethanol, faces challenges as the search for microorganisms capable of fermenting pentoses with ...
Utilização do metabissulfito de potássio no processo de fermentação etanólica para controle de leveduras e bactérias contaminantes
(Universidade Federal de São Carlos, 2017-04-11)
One of the main concerns in the ethanol-producing industries is the
growth control of undesirable microorganisms that can cause decrease in the
fermentative yield. Among non-Saccharomyces yeasts which can contaminate ...
