Recent Advances In Fermentation of Lignocellulosic Biomass Hydrolysate to Ethanol |
During the last pastdecades considerably large efforts have been made to optimize the production oflignocellulose derived fuel ethanol production which is economically feasible.Lignocellulosic materials serve as abundant feedstock, to produce fuel ethanolfrom renewable resources at reasonable costs. Following the pretreatment, the enzymatichydrolysis process can be run separately (SHF) or simultaneously (SSF) withfermentation. But, there are some technological barriers such as toxicinhibitors released from the pretreatment of lignocellulosic feedstock’s, lowerscarification rates by enzymes and simultaneous and rapid fermentation ofhexoses and pentose sugars, which needs to be addressed for efficientconversion of lignocellulosic biomass to bioethanol. The review paper coversall these aspects, challenges and development in the field of fermentation.
