11. Identification and characterisation of chitin and cellulose synthases in oomycetes : New tools for biochemical studies and structure determination
Abstract : Despite resembling ‘true’ fungi in terms of morphological features, oomycetes form a distinct eukaryotic lineage of filamentous microorganisms that belongs to the stramenopiles, a group of protists also comprising the closely-related brown algae and diatoms. Many oomycetes are devastating pathogens of plants and animals, globally causing significant economic losses in the agriculture and aquaculture industries, and posing considerable environmental damage to natural ecosystems.

12. Computational discovery of antibiotic resistance genes and their horizontal transfer
Abstract : Antibiotic resistance is increasing among clinical infections and represents one of the most serious threats to public health. Pathogens often become resistant by acquiring mobile antibiotic resistance genes (ARGs) via horizontal gene transfer (HGT). READ MORE

13. Evolution of human alpha-herpesviruses
Abstract : Herpesviridae is a large virus family with more than 100 members, which are highly disseminated among animals. Three sub-families have been classified; alpha-herpesviruses, beta-herpesviruses and gamma-herpesviruses. READ MORE

14. galactmannan degradation by fungi and gut bacteria : structural enzymology and fine -tuned substrate specifcity
Abstract : AbstractThe degradation of plant based β-mannan polysaccharides represents one of the many challenges efficiently tackled by microorganisms living in different habitats. In this thesis, glycoside hydrolases (GHs) involved in mannan degradation from two different organisms, Aspergillus nidulans (paper I and II) and Bacteroides ovatus (paper III and IV) were studied.

15. Taxonomy and phylogeny of Dermatocarpon (Verrucariales, lichenized Ascomycotina) with special emphasis on the Nordic species
Abstract : In this thesis Dermatocarpon (Verrucariales, lichenized Ascomycotina) of the Nordic countries is revised. Useful characters for species identification are epinecral layer type, spore length, medulla sensitivity to Melzer´s Reagent, and lower surface colour anappearance. READ MORE
