LORRE Seminars Our weekly seminars will be held on Mondays 4-5pm! All LORRE graduate students are expected to attend. Seminar on Monday October 6th will be by Daehwan Kim in the Fu Room (POTR 234). Adaptation of Yeast to Inhibitors and Ethanol Fermentation of Biobated Lignocellulosic Substrates Abstract: Phenols produced by high plants for defense mechanism are believed to play key role in inhibition of enzyme hydrolysis (Ximenes 2010, 2011; Kim et al. 2013, 2014; Cao et al. 2013; Ko et al. 2014). Several products released during pretreatment of lignocellulosic materials such as phenols including lignin degradation products, tannins and gallic acid are also major inhibitors that can reduce enzyme activity (Ximenes 2010, 2011). Saccharomyces cerevisiae is the most useful yeast for fermentation of foods and ethanol. If S. cerevisiae has a tolerance of phenol compounds or can use these compounds as source of carbon and energy, we can expect that it could contribute to economically feasible biofuel production. From this study, we are attempted to adapt the Y-1546 yeast on several pretreated liquid which have high phenols for survival, and have tested if adapted Y-1546 yeast is improved to use the glucose and produce the ethanol than original yeast and/or other yeast.
