Abstract To date, there is limited knowledge available regarding the key features of pretreated lignocellulosic substrates that promote effective enzymatic hydrolysis cellulose component to glucose during bioconversion processes produce ethanol. Fundamentally, cellulase enzymes require access carry out hydrolysis. Porosity and overall surface area have major structural influencing by cellulases. Simons' Stain (SS) a potentially useful semiquantitative method for estimating substrates. In...
Abstract Utilization of ethanol produced from biomass has the potential to offset use gasoline and reduce CO 2 emissions. This could effects global warming, one which is current outbreak epidemic proportions mountain pine beetle (MPB) in British Columbia (BC), Canada. The result this increasing volumes dead lodgepole with increasingly limited commercial uses. Bioconversion using SO ‐catalyzed steam explosion was investigated. optimum pretreatment condition for feedstock determined be 200°C,...
Abstract Background A substantial barrier to commercialization of lignocellulosic ethanol production is a lack process specific sensors and associated control strategies that are essential for economic viability. Current analytical techniques require lengthy offline analysis or easily fouled in situ. Raman spectroscopy has the potential continuously monitor fermentation reactants products, maximizing efficiency allowing improved control. Results In this paper we show glucose can be...
Abstract The production of fuels and chemicals from lignocellulosic biomass demands efficient processes to compete with fossil fuel-derived products. Key biorefinery processes, such as enzymatic hydrolysis cellulose microbial fermentation, can be monitored by advanced sensors in real time, providing information about reactant product concentration, contamination, reaction progress. Spectroscopic techniques Raman spectroscopy provide a means quickly accurately assessing many types mixtures...
The focus of this study was to assess the feasibility using giant reed (Arundo donax) for bioethanol production via pretreatment, enzymatic hydrolysis, and fermentation. Sugar ethanol yields from were compared with those hybrid poplar, a well-regarded woody biomass feedstock. Low (L), medium (M), high (H) severity steam pretreatment conditions applied select set that would allow recovery maximum amount sugars in hydrolysable fermentable form. Simultaneous saccharification fermentation (SSF)...
Use of a commodity feedstock with uniform physical and chemical characteristics can maximize the efficiency sugar production in lignocellulosic biorefinery. However, efficient handling storage necessitates dry biomass, while effective bioconversion is maximized high moisture biomass. To bridge this gap, effect content on hybrid poplar was investigated. Fresh chips were both oven- air-dried rehydrated by soaking water prior to SO2-catalyzed steam explosion. Following enzymatic hydrolysis,...
