Abstract: Among the native yeasts found in alcoholic fermentation, rough colonies associated with pseudohyphal morphology belonging to the species Saccharomyces cerevisiae are very common and undesirable during the process. The aim of this work was to perform morphological and physiological characterisations of S. cerevisiae strains that exhibited rough and smooth colonies in an attempt to identify alternatives that could contribute to the management of rough colony yeasts in alcoholic fermentation. Characterisation tes… Show more

“…Isolates were characterized by their cultural and morphological characteristics following the protocols as described by Reis et al (2013). After incubation, cultural and morphological characteristics were observed by visible growth pattern followed by simple staining and microscopic observation.…”

“…However, yeast cells have mechanisms of stress response to industrial conditions of fermentation and acid treatment 42, 43. Trehalose and glycogen are reserve carbohydrates for additional energy when cells are starved for sugars 44, 45.…”

“…Previous investigations show that the acid treatment utilized in the Brazilian industry can inhibit the growth of the "rough strains" to a certain degree, and can also be applied as a tool to avoid spoilage and minimize damages caused by rough strains, due to their peculiar metabolic profile (Reis et al, 2013). However, the so-called "rough strains" are usually variants of smooth colony S. cerevisiae.…”
