16. Molecular mechanisms involved in prokaryotic cycling of labile dissolved organic matter in the sea
Sammanfattning : Roughly half of the global primary production originates from microscopic phytoplankton in marine ecosystems, converting carbon dioxide into organic matter. This organic matter pool consists of a myriad of compounds that fuel heterotrophic bacterioplankton. LÄS MER
17. Studies on endoribonuclease RNase E and its role in RNA turnover
Sammanfattning : RNA turnover is an important level of regulation of gene expression, by which a cell can rapidly adjust to changes in its environment. The turnover of RNA is done by an efficient but not well understood mechanism. LÄS MER
18. Structure determination of Methanocaldococcus jannaschii nucleoside kinase
Sammanfattning : All organisms can be divided into the tree kingdoms of life: Archaea, Bacteria and Eukarya. Archaeal organisms are often found to exhibit, compared to human perspectives, extreme environments, such as high temperature, high salt and acidic habitats. Many archaeal species are hyperthermophiles, i.e. LÄS MER
19. On the cell cycle of Escherichia coli and cell division in Haloferax mediterranei
Sammanfattning : Escherichia coli has served as a model organism for prokaryotes for several decades and is perhaps the most well characterised organism on earth. The use of fluorescence microscopy during recent years has contributed substantially to our understanding of the essential cell cycle processes chromosome replication, chromosome segregation and cell division.

20. Microbial diversity in Baltic Sea sediments
Sammanfattning : This thesis focuses on microbial community structures and their functions in Baltic Sea sediments. First we investigated the distribution of archaea and bacteria in Baltic Sea sediments along a eutrophication gradient. LÄS MER
