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

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

   Sammanfattning : 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. LÄS MER

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

   Författare :Ronny Purwadi; Högskolan i Borås; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

   Författare :Ria Millati; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. Ethanol Production from Cellulosic Biomass by Encapsulated Saccharomyces cerevisiae

   Författare :Farid Talebnia; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; encapsulated cells; ethanol; s.cerevisiae; dilute-acid hydrolyzate; in situ detoxification; furfural; orange peels; experimental design; immobilization; limonene;

   Sammanfattning : Unstable oil markets with rising environmental concerns have revived widespread interest in production of fuel ethanol from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cheap ethanol production. However, due to recalcitrant structure of these materials, pretreatment is a prerequisite. LÄS MER

7. 5. Microbial Biofilms in the Bioinformatics Era

   Författare :Kemal Sanli; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metagenomics; bioinformatics software; microbial biofilms; Next Generation Sequencing; pathway analysis; periphyton; marine biofilms; FANTOM; PACFM; PACFM;

   Sammanfattning : Adverse effects of anthropogenic impact on the environment have become conspicuous in the past century and among others include the gradual increase in the global CO2 levels, the contamination of air, soil and water by toxic chemicals, and the emergence of antimicrobial resistance among pathogenic microbial species. Microorganisms partake in an extreme diversity of activities in the environment, and hence, constitute the prime candidates to be investigated in understanding of the progression and effects of the aforementioned environmental hazard scenarios.
