The objective of this project is to develop a process for the parallel production of ethanol and cellulose in a pulp mill, by applying a prehydrolysis step to softwood chips to extract hexose sugars for their subsequent fermentation in ethanol. Two kinds of pretreatments were compared, an acid hydrolysis and a two-step treatment composed of an autohydrolysis and a post-hydrolysis of the resulti...
BACKGROUND Pretreatment of biomass for lignocellulosic ethanol production generates compounds that can inhibit microbial metabolism. The furan aldehydes hydroxymethylfurfural (HMF) and furfural have received increasing attention recently. In the present study, the effects of HMF and furfural on redox metabolism, energy metabolism and gene expression were investigated in anaerobic chemostats whe...
BACKGROUND Lignocellulosic biomass is a promising source of renewable biofuels. However, pretreatment of lignocellulosic biomass generates fermentation inhibitors that adversely affect the growth of industrial microorganisms such as Saccharomyces cerevisiae and prevent economic production of lignocellulosic biofuels. A critical challenge on developing S. cerevisiae with improved inhibitor resis...
Although concentrated sulfuric acid saccharification is not a novel method for breaking down lignocellulosic biomass, the process by which saccharification affects biomass decomposition, sugar recovery, and by-product generation is not well studied. The present study employed Taguchi experimental design to study the effects of seven parameters on corn stover concentrated sulfuric acid saccharif...
Abstract Furfural content in oil is considered as an effective parameter to evaluate the ageing state of oil‐immersed transformers. In previous thermal experiments at 130°C, we found that moisture increment oil‐paper system makes more furfural distribute oil. However, microcosmic mechanism effect on diffusion from paper still unknown, and equilibrium law transformers' typical operating temperat...
