Based on the experimental results of this study and with the above advantages in mind, it is suggested by the authors
that the thermotolerant ethanol-producing yeast strain tested represents a novel candidate for use in simultaneous saccharification and conversion of cellulosic substrates to ethanol at 42◦C in the presence of exogenously added cellulases Steam explosion pretreatment of materials tested is shown to be an efficient way to enhance process yields. Nevertheless, it is assumed that yields obtained are all relatively low for industrial ethanol production processes and that further improvements in terms of increased ethanol yields, are
necessary to achieve an economical process. Research on advanced reactor configurations, which allow the fermentation to ethanol process in a fed-batch basis, appears to be
a promising means to increase final ethanol yields in SSF
process.
