Cardoon Hydrolysate Detoxification by Activated Carbon or Membranes System for Bioethanol Production

Advanced biofuels incorporation into the transportation sector, particularly cellulosic bioethanol, is crucial for attaining carbon neutrality by 2050, contributing to climate changes mitigation and wastes minimization. The world needs biofuel be commercially available tackle socioeconomic challenges coming from continued use of fossil fuels. Cynara cardunculus (cardoon) a cheap lignocellulosic raw biomass that easily grows in Mediterraneous soils potential renewable resource biorefinery. This work aimed study bioethanol production cardoon hemicellulosic hydrolysates, which originated dilute sulfuric acid hydrolysis pretreatment. A detoxification step remove released microbial fermentative inhibitors was evaluated using both activated adsorption nanofiltration membrane system. Scheffersomyces stipitis CBS5773 yeast modified Escherichia coli MS04 fermentation performances at different experimental conditions were compared. promising results with E. coli, detoxified nanofiltration, led volumetric productivity 0.30 g·L?1·h?1, conversion efficiency 94.5%. Regarding S. stipitis, similar conditions, 0.091 g·L?1·h?1 64.9% obtained. Concluding, through hydrolysate presents suitable alternative second-generation especially coli.
