"The yeasts used in the production of second generation ethanol are affected by inhibitory compounds as 5-hydroxymethylfurfural(HMF) and furfural that are releasing during the hydrolysis step; these compounds affect the fermentative capacities of the yeast.To find new yeast strains with outstanding capacities to be used in the production of second generation ethanol; in this study, weevaluated the physiological response to furan derivatives stress by native yeastKluyveromyces marxianus(SLP1), and comparedit with the commercial yeastSaccharomyces cerevisiaeethanol red (ERD). We used a chemically defined medium added withHMF and furfural at different concentrations; a control condition without inhibitors, and four stressing conditions, HMF 7 gL−1,furfural 3gL−1, HMF 3.5 gL−1with furfural 1.5 gL−1, and HMF 7 gL−1with furfural 3 gL−1.K. marxianusexhibited a greatercapacity to assimilate the inhibitory compounds in less time thanS. cerevisiaeERD; also,K. marxianusSLP1 strain showedbetter behavior to produce ethanol on inhibitory conditions. Despite the effects provoked by the inhibitory compounds, the yeastscould produce ethanol over 80% of conversion. In conclusion, the yeastK. marxianusSLP1 can be an option to produce secondgeneration ethanol at industrial level". | |
