1. Continuous Ethanol Production from Dilute-acid Hydrolyzates: Detoxification and Fermentation Strategy
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
2. Overliming and continuous cultivation of dilute-acid hydrolyzates by immobilized Baker's yeast, S. cerevisiae
Sammanfattning : .... LÄS MER
3. 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
4. Fermentation of Lignocellulosic Hydrolysates: Inhibition and Detoxification
Sammanfattning : The ethanol yield and productivity obtained during fermentation of lignocellulosic hydrolysates is decreased due to the presence of inhibiting compounds, such as weak acids, furans and phenolic compounds produced during hydrolysis. Evaluation of the effect of various biological, physical and chemical detoxification treatments by fermentation assays using Saccharomyces cerevisiae was used to characterise inhibitors. LÄS MER
5. Lactic acid production: extractive fermentation in aqueous two-phase systems
Sammanfattning : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.
