4. 2. Ethanol Production from Lignocellulosic Materials: Potential of Continuous Cultivation, Immobilisation, and Zygomycetous Fungi

   Author : Ria Millati; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuous cultivation; galactose; Rhizopus; xylose; Rhizomucor; S cerevisiae; Mucor; M indicus; glucose; immobilisation; detoxification; arabinose; mannose; overliming; ethanol; dilute-acid hydrolysate;

   Abstract : This thesis deals with the production of bio-ethanol, a sustainable alternative to fossil fuels, from dilute-acid lignocellulosic hydrolysate in a continuous immobilised cell system and fermentation of the hydrolysate by a zygomycete organism, M. indicus. READ MORE

5. 3. Continuous Ethanol Production from Dilute-acid Hydrolyzates: Detoxification and Fermentation Strategy

   Author : Ronny Purwadi; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMF; serial bioreactor; immobilization; overliming; furfural; ethanol; continuous cultivation; S. cerevisiae; flocculating yeast; continuous detoxification; dilute-acid hydrolyzate;

   Abstract : The production of fuel ethanol from cellulosic biomass is of growing interest around the world. Lignocellulosic residuals can be used to produce transportation fuel, with the overall process having little net production of greenhouse gases. READ MORE

6. 4. Fermentation Inhibitors in the Production of Bio-ethanol: Detoxification of Lignocellulose Hydrolyzates and Physiological Effects of Furfural on Yeast

   Author : Ilona Sárvári Horváth; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; detoxification; fermentation inhibitors; metabolic flux analysis; Saccharomyces cerevisiae; lignocellulose; ethanol; chemostat; furfural conversion;

   Abstract : Different strategies to overcome inhibitor problems in the production of bio-ethanol from lignocellulose hydrolyzates with the yeast Saccharomyces cerevisiae were examined. The strategies included detoxification prior to fermentation and in situ detoxification of furfural. A strain development for improved inhibitor tolerance was also initiated. READ MORE

7. 5. Ethanol from lignocellulose : Alkali detoxification of dilute-acid spruce hydrolysates

   Author : Björn Alriksson; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Kemi; Chemistry;

   Abstract : Detoxification of dilute-acid lignocellulose hydrolysates by treatment with Ca(OH)2 (overliming) efficiently improves the production of fuel ethanol, but is associated with drawbacks like sugar degradation and CaSO4 precipitation. In factorial designed experiments, in which pH and temperature were varied, dilute-acid spruce hydrolysates were treated with Ca(OH)2, NH4OH or NaOH. READ MORE
