Many researchers have reported on the production of bioethanol
from a wide variety of strains and agro-industrial wastes
under optimized conditions. Arapoglou et al. [23] presented a new
form of potato peel waste hydrolysis with a specific combination of
enzymes and hydrochloric acid, subsequently fermented by
Saccharomyces cerevisiae var. bayanus to enhance bioethanol production.
According to their results, 18.5 g/L reducing sugar was
released and 7.6 g/L bioethanol was produced after fermentation.
The maximum bioethanol production in our study was nearly 1.2
times higher than the bioethanol production obtained by Arapoglou
et al. [23]. Moreover, orange peels were used as fermentation
raw material for bioethanol production [26]. Bioethanol yields of
0.25 g/g on a biomass basis, 0.46 g/g on a substrate basis were
obtained which are quite lower than the ones found in the current
study.
