1. Evolution of symbiotic lineages and the origin of new traits
Abstract : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. READ MORE

2. Molecular mechanisms and biological consequences of the production of non-canonical D-amino acids in bacteria
Abstract : Most bacteria possess a vital net-like macromolecule – peptidoglycan (PG). PG encases bacteria around the cytoplasmic membrane to withstand the high internal turgor pressure and thereby protect the cell from bursting. In addition, PG is a major morphological determinant of bacteria being both required and sufficient to maintain cell shape. READ MORE

3. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments
Abstract : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. READ MORE

4. Microbially mediated manganese oxides enriched in yttrium and rare earth elements in the Ytterby mine, Sweden
Abstract : Microorganisms are able to manipulate redox reactions and thus exert extensive control on chemical speciation and element partitioning in nature, affecting the formation and dissolution of certain minerals. One of these redox active elements is manganese (Mn), which in its oxidized states (III/IV), commonly forms Mn oxide-hydroxide minerals. READ MORE
