Abstract EN
This paper opens up a new issue dealing with Luffa cylindrica (LC) lignocellulosic biomass recovery in order to produce 2G bioethanol.
LC fibers are composed of three principal fractions, namely, α-cellulose (45.80% ± 1.3), hemicelluloses (20.76% ± 0.3), and lignins (13.15% ± 0.6).
The optimization of LC fibers hydrothermal and diluted acid pretreatments duration and temperature were achieved through the cubic central composite experimental design CCD.
The pretreatments optimization was monitored via the determination of reducing sugars.
Then, the 2G bioethanol process feasibility was tested by means of three successive steps, namely, LC fibers hydrothermal pretreatment performed at 96°C during 54 minutes, enzymatic saccharification carried out by means of a commercial enzyme AP2, and the alcoholic fermentation fulfilled with Saccharomyces cerevisiae.
LC fibers hydrothermal pretreatment liberated 33.55 g/kg of reducing sugars.
Enzymatic hydrolysis allowed achieving 59.4 g/kg of reducing sugars.
The conversion yield of reducing sugar to ethanol was 88.66%.
After the distillation step, concentration of ethanol was 1.58% with a volumetric yield about 70%.
