1. Recalcitrance of wood to biochemical conversion : feedstock properties, pretreatment, saccharification, and fermentability
Abstract : 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. READ MORE

2. Fundamental Aspects of Lignin Carbohydrate Complexes (LCC) : Mechanisms, Recalcitrance and Material concepts
Abstract : Covalent bonds between lignin and carbohydrates, forming a matrix referred to as lignin carbohydrate complexes (LCC), remain one of the most controversial topics in wood chemistry. A key issue is whether they are formed during chemical and mechanical pretreatments of the compact wood structure or actually present in wood prior to isolation. READ MORE

3. Waste Textiles Bioprocessing to Ethanol and Biogas
Abstract : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE

4. Salix as a biorefinery feedstock : an inquiry into factors affecting conversion performance
Abstract : Lignocellulosic biomass is one of the world’s greatest natural resources, with po-tential for replacing a considerable portion of current fossil resource use. Although lignocellulosic biomass can be readily utilized for generating heat and power via combustion, its conversion into storable fuels such as ethanol and biogas presents a greater challenge.

5. Process development for platform chemical production from agricultural and forestry residues
Abstract : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pretreatment impair the economic feasibility of such biorefineries. READ MORE
