These values
are similar to the previous report using rice straw liquid hydrolysates
and recombinant S. cerevisiae (0.36–0.49) (Matsuda et al.,
2011). The production of glycerol and xylitol was low
(0.63 ± 1.20 and 0.11 ± 0.14 g L–1, respectively). These results show
that ethanol fermentation of concentrated liquid hydrolysates of
dilute acid-pretreated rice straw using recombinant S. cerevisiae
can be conducted efficiently.
