11. Functional Profiling Of Metabolic Regulation In Marine Bacteria
Sammanfattning : Oceans are powered by active, metabolically diverse microorganisms, which are important in regulating biogeochemical cycles on Earth. Most of the ocean surface is often limited by nutrients, influencing bacterial growth and activities. LÄS MER
12. Evolution of streamlined genomes in ultra-small aquatic bacteria
Sammanfattning : This thesis investigates the evolutionary processes of streamlined genomes from aquatic bacteria adapting to different salinities, using two groups of ultra-small aquatic bacteria (LD12 Alphaproteobacteria and acI Actinobacteria). Due to difficulties in obtaining pure cultures of these bacteria, culture-free approaches (single-cell genomics and metagenomics) were used to construct and compare genomes, and to study the mechanisms and selective forces of adaptation to freshwater, brackish, and marine ecosystems.

13. Antimicrobial materials from cellulose using environmentally friendly techniques
Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

14. Proteomic profiling of bacterial host adaptation : Racing the Red Queen
Sammanfattning : Despite the discovery of antibiotics almost a century ago, infectious diseases continue to be a substantial cause of human mortality and morbidity worldwide, especially in developing countries. The adverse affects of infectious diseases are thought to increase over the coming years as the widespread misuse of antibiotic leads to the emergence of strains for which current therapies are ineffective.

15. On the repair of the dentine barrier
Sammanfattning : Det övergripande målet för avhandlingen har varit att studera några aspekter av läkningen av tandens huvudsakliga hårdvävnad, dentinet. Vid mycket djupa kariesangrepp där dentinet förstörts och pulpan därmed blottats, rotbehandlas ofta tanden vilket innebär att pulpan tas bort och att rotkanalen fylls med ett rotfyllningsmaterial.
