1. Walking the Plank of the Entrepreneurial University : The little spin-out that could?
Abstract : Creating spinout companies (USOs) from university research is one focus of innovation policy. The phenomenon features in two main fields of enquiry: academic entrepreneurship studies, and literature on academic capitalism and the entrepreneurial university. READ MORE

2. Towards More Robust Saccharomyces cerevisiae Strains for Lignocellulosic Bioethanol Production: Lessons from process concepts and physiological investigations
Abstract : Dwindling oil reserves and the negative impacts of fossil fuels on the environment call for more sustainable energy sources. First-generation bioethanol produced from sugar cane and corn has met some of these needs, but it competes with the food supply for raw materials. READ MORE

3. Concepts for improving ethanol productivity from lignocellulosic materials : encapsulated yeast and membrane bioreactors
Abstract : Lignocellulosic biomass is a potential feedstock for production of sugars, which can be fermented into ethanol. The work presented in this thesis proposes some solutions to overcome problems with suboptimal process performance due to elevated cultivation temperatures and inhibitors present during ethanol production from lignocellulosic materials.

4. 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

5. Ethanol production from lignocellulose using high local cell density yeast cultures. Investigations of flocculating and encapsulated Saccharomyces cerevisiae
Abstract : Efforts are made to change from 1st to 2nd generation bioethanol production, using lignocellulosics as raw materials rather than using raw materials that alternatively can be used as food sources. An issue with lignocellulosics is that a harsh pretreatment step is required in the process of converting them into fermentable sugars. READ MORE
