Negative H2S character and flocculation as yeast strain markers for inoculum recovery

Abstract: Routine identification of yeast behavior is essential to measure the control of the alcohol production process and to maintain product quality standards. This work utilized the non-hydrogen sulfide production and flocculation traits as characteristic strain markers for the evaluation of cell recycling during the alcoholic fermentation process for production of sugarcane alcohol. This study evaluated the behavior of a recombinant yeast bank made by protoplast fusion, for strain screening purposes; strain fermen… Show more

“…Segregant colonies were also tested for their ability to grow in stressing conditions such as high temperature (37°C, YPD agar medium, 3 days incubation) or high alcohol concentration (YP medium supplemented with ethanol 10%, v/v). Growth on YP media (yeast extract, 1% and peptone, 1%, w/v) containing ethanol or glucose was scored by visual inspection after 3 days of incubation at 30°C (Ribeiro and Horii 2004).…”
