Production d'éthanol a partir de biomasse lignocellulosique

Abstract: Résumé -Cette étude fait le point des connaissances scientifiques et techniques dans le domaine de la production alcoolique à partir de susbstrats lignocellulosiques. Ce travail, réalisé dans le cadre d'Agrice (Agriculture pour la chimie et l'énergie), est une synthèse bibliographique qui a cherché à identifier les avancées capables de débloquer certains verrous technologiques et économiques liés à ce type de procédé. La biomasse lignocellulosique est un substrat complexe, constitué des trois principales fract… Show more

“…Among the 200 species of yeast examined for the production of ethanol from xylose, Candida shehatae and Pichia stipitis present the best performances in terms of yield and productivity [37]. Those two yeasts have been studied for ethanol production [11,3,28,2]. One of the best performances was obtained with C. shehatae in fed-batch culture with xylose [12]: an ethanol concentration of 44 g l -1 was reached with a yield of 0.34 g g -1 .…”

“…A key step in the bioconversion of lignocellulosic biomass is saccharification, that is, the degradation of the plant cell wall polysaccharides into soluble sugars that can be used by microorganisms for fermentation. Currently, enzymatic hydrolysis is the most promising and environmentally friendly technology available for saccharification [3]. However, a major bottleneck for the industrial implementation of biomass utilization is the natural recalcitrance of the plant cell walls to enzymatic hydrolysis [4].…”

“…1 Various configurations of biologically mediated processing steps during the biocatalytic conversion of lignocellulose and highlight on hydrolysis step with and without interaction with cell cultures. Abbreviations: separate hydrolysis and fermentation (SHF), separate hydrolysis and co-fermentation (SHCF), simultaneous saccharification and fermentation (SSF), simultaneous saccharification and co-fermentation (SSCF), and consolidated bioprocessing (CBP) conditions [3]. An enzyme-based process can be divided into four principal steps ( Fig.…”
