1. Fractionation of woody biomass : lignin and suberin in focus
Sammanfattning : This thesis is dedicated to the research of fractionation and valorization of different types of woody biomass. In the first part, oak (Quercus suber) and birch (Betula pendula) barks are considered. Bark is the outer layer of wood and is treated as waste in the current wood processing technologies. LÄS MER
2. Suberin based polyesters
Sammanfattning : In the wish to replace oil-based chemicals and materials with such based on biodegradable and renewable resources, this work has been performed. In a biorefinary concept, waste birch bark from paper pulp mills and timber production has been evaluated as a potential source for polyesters. LÄS MER
3. The Use of Lignin Derivatives to Improve Selected Paper Properties
Sammanfattning : Ved består huvudsakligen av tre typer av polymerer, cellulosa, hemicellulosa och lignin. Lignin bildas i naturen genom enzymatiskt initierad oxidativ koppling av tre olika typer av fenylpropan-enheter. Dessa bygger genom olika kol-kol- och kol-syre-bindningar upp en amorf tredimensionell polymer. LÄS MER
4. Strategies for improving kraftliner pulp properties
Sammanfattning : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. LÄS MER
5. Host organelles and transporters in underground plant-pathogen interactions
Sammanfattning : This thesis covers studies of three different soilborne plant pathogens, the two fungi, Rhizoctonia solani and Verticillium longisporum, and the protist Plasmodiophora brassicae, as well as their host responses. Based on genome sequence analysis of the pathogens and their plant hosts, different effectors and plant defence factors were predicted. LÄS MER
