Resumo: | Although there are several studies using yeasts, little is known about the physiological behaviour of yeasts Saccharomyces cerevisiae, mainly about industrial strains that are responsible for the production of ethanol and its adaptation to different environments. Thus, this study aims to evaluate the influence of the action of white and ultraviolet light associated with other stress factors in the fermentative medium and to analyze the fermentative performance of yeast FT-858 under different growing conditions. The yeast was grown in liquid medium (2% YPD) at 30°C for 12 hours at 250 rpm. After this period, the cells were recovered by centrifugation and inoculated into the fermentation medium based on sugarcane juice and sweet sorghum at concentrations of 18, 28 and 32° Brix, which were incubated at 30 and 42°C for 10 hours at 250 rpm, under the action of white light (BR), ultraviolet (UV) and without light (S / L), promptly analysing the physiological parameters. The fermentative performance of the yeast was affected when exposed to UV light at the highest Brix concentration and high temperature. |
