1. Recalcitrance of wood to biochemical conversion : feedstock properties, pretreatment, saccharification, and fermentability
Sammanfattning : Lignocellulose is an inexpensive and abundant renewable resource that can be used to produce advanced biofuels, green chemicals, and other bio-based products. Pretreatment and efficient enzymatic saccharification are essential features of bioconversion of lignocellulosic biomass. LÄS MER
2. Biochemical conversion of biomass : hydrothermal pretreatment, by-product formation, conditioning, enzymatic saccharification, and fermentability
Sammanfattning : Lignocellulosic residues have great potential as feedstocks for production of bio-based chemicals and fuels. One of the main routes is biochemical conversion, which typically includes pretreatment, enzymatic saccharification, microbial fermentation of sugars, and valorization of hydrolysis lignin. LÄS MER
3. Ethanol from Lignocellulose - Fermentation Inhibitors, Detoxification and Genetic Engineering of Saccharomyces cerevisiae for Increased Resistance
Sammanfattning : Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars, and then fermenting the hydrolysate with the yeast Saccharomyces cerevisiae. Hydrolysis using dilute sulphuric acid has advantages over other methods, however, compounds which inhibit fermentation are generated during this kind of hydrolysis. LÄS MER
4. Ethanol from lignocellulose : Alkali detoxification of dilute-acid spruce hydrolysates
Sammanfattning : 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. LÄS MER
5. 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
