1. Fermentation of undetoxified dilute acid lignocellulose hydrolysate for fuel ethanol production
Sammanfattning : Important aspects of ethanol production from undetoxified dilute acid lignocellulose hydrolysate are covered in this thesis, which primarily focuses on the use of Saccharomyces cerevisiae (Baker's yeast) as the biocatalyst. Nine different strains of S. LÄS MER
2. Countercurrent operation in the dilute-acid hydrolysis of cellulose for ethanol production
Sammanfattning : Fuel ethanol can be produced from lignocellulosic materials to replace gasoline and diesel. A crucial step in the production process is the hydrolysis (saccharification) of the material, which can be achieved with dilute acid at high temperature. Unfortunately, sugar is degraded under these severe conditions, and the sugar yield is generally low. LÄS MER
3. Ethanol Production from Lignocellulosic Materials: Potential of Continuous Cultivation, Immobilisation, and Zygomycetous Fungi
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
4. Ethanol from lignocellulose : Management of by-products of hydrolysis
Sammanfattning : Fuel ethanol can be produced from lignocellulosic materials, such as residues from agriculture and forestry. The polysaccharides of lignocellulose are converted to sugars by hydrolysis and the sugars can then be fermented to ethanol using microorganisms. However, during hydrolysis a wide range of by-products are also generated. LÄS MER
5. Fermentation of lignocellulosic material : a study on bacterial contamination and yeast physiology
Sammanfattning : Progressive depletion of oil and conventional fossil fuels, an increased energy demand and an increased struggle for national energy security has led to the development of alternative biobased fuels, bioethanol being one of them. Bioethanol can be made from many different raw materials, and based upon this are classified as 1st generation and 2nd generation. LÄS MER
