The available glucose from 100 g dried OPT reached
53.5 g, comprised of 26.9 g of starch as glucose and 26.6 g
of cellulose as glucose. Two different processes were applied
to the production of ethanol from OPT. The glucose
yield from CECP was 43.5 g (81.3 % of TGY), and the
resulting ethanol yield was 22.3 g (81.4 % of TEY). In contrast,
EECP converted as much starch and cellulose as
possible into glucose, i.e., 25.9 g from the starch and
25.6 g from cellulose, which equated to 96.3 % of TGY.
The resulting ethanol yield from EECP of 25.6 g (93.5 % of
TEY) was 10 % more than that from CECP. These study
results confirmed the potential of EECP for use in maximizing
ethanol production from OPT through effective
starch utilization while minimizing its loss.
