which might suggest that more acids were produced to generate ATP
for cell metabolism
when exposed
to
inhibiting
environment.
Butanol production from acid hydrolyzed sugarcane bagasse was reported
by Soni et al. [27]
and this process only produced 3.5 g/L butanol,
while 10.8 g/L butanol was obtained after detoxification with active carbon.
In present study,
sugarcane bagasse hydrolysate with low concentration of inhibitors was generated by using GVL/water solution and high concentration of butanol was produced without any detoxification step,
which will greatly contribute to the low-cost production of biobutanol.
