1. Sustainability of the Swedish Sugar Sector : Assessment Tool Development and Case Study Appraisal
Sammanfattning : This thesis contributes to the development of tools and methods for assessing sustainability and applies them to an assessment of the Swedish sugar production system. The thesis’ aims are to compile an overview of the existing approaches for assessing sustainability, to suggest a method(s) for structuring and analyzing complex sustainability issues, and to appraise sustainability impacts from Swedish sugar production.

2. UDP-sugar metabolizing pyrophosphorylases in plants : formation of precursors for essential glycosylation-reactions
Sammanfattning : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.

3. Tailoring the self-assembly, interfacial properties and rheological behaviour of sugar-based surfactants
Sammanfattning : Surfactants are important ingredients in many formulated products used in everyday life. Many of these surfactants originates from fossil-based materials and degrades slowly in aquatic systems. LÄS MER
4. Sugar-modulated gene expression and cell division in cell culture and seedlings of A. thaliana
Sammanfattning : Throughout their life cycle, plants adjust growth in response to their developmental and environmental situation within the limits of their energetic capacities. This capacity is defined by the local sugar availability, which is constantly modulated through synthesis, transport and consumption of sugar. LÄS MER
5. Towards sugar- and lignin-based polyesters and polyurethanes with enhanced properties
Sammanfattning : The enormous production and consumption of fossil-based plastics has caused severe environmental challenges such as pollution of the ocean, increased CO2-emissions, and various health problems. Many ofthese concerns are intimately connected to the use of fossil fuels in the production of polymers. LÄS MER
