- Abundance and diversity of Archaea in heavy-metal-contaminated soilsR A Sandaa
Department of Microbiology, University of Bergen, N 5020 Bergen, Norway
Appl Environ Microbiol 65:3293-7. 1999..Analysis of cloned 16S ribosomal DNA showed close similarities to a unique and globally distributed lineage of the kingdom Crenarchaeota that is phylogenetically distinct from currently characterized crenarchaeotal species...
- Isolation and characterization of two viruses with large genome size infecting Chrysochromulina ericina (Prymnesiophyceae) and Pyramimonas orientalis (Prasinophyceae)R A Sandaa
Department of Microbiology, University of Bergen, Postbox 7800, N 5020, Bergen, Norway
Virology 290:272-80. 2001..The Chrysochromulina virus clone CeV-01B and the Pyramimonas virus clone PoV-01B described in this study have several properties in common with other viruses infecting microalgae, suggesting that they belong to the Phycodnaviridae...
- Virioplankton community structure along a salinity gradient in a solar salternRuth Anne Sandaa
Department of Microbiology, University of Bergen, Jahnebakken 5, 5020 Bergen, Norway
Extremophiles 7:347-51. 2003..The diversity index was highest in the environments that lie in between the most extreme and the most common...
- Characterisation of the bacterial community associated with early stages of Great Scallop (Pecten maximus), using denaturing gradient gel electrophoresis (DGGE)Ruth Anne Sandaa
Institute of Marine Research, Bergen, Norway
Syst Appl Microbiol 26:302-11. 2003..To our knowledge this is the first study investigating bacterial communities associated with Great Scallop larvae in different aquaculture systems including noncultured components...
- Phylogenetic analysis of members of the Phycodnaviridae virus family, using amplified fragments of the major capsid protein geneJ B Larsen
Institute of Biology, University of Bergen, Jahnebakken 5, N 5020 Bergen, Norway
Appl Environ Microbiol 74:3048-57. 2008..This shows that closely related sequences of this family are present at geographically distant locations within the marine environment...
- Genomic sequence and analysis of EhV-99B1, a new coccolithovirus from the Norwegian fjordsA Pagarete
Department of Biology, University of Bergen, NO 5006 Bergen, Norway
Intervirology 56:60-6. 2013..As a whole, this study provided new clues and insights into the diversity and mechanisms driving the evolution of these large oceanic viruses, in particular those processes involving selfish genetic elements...
- Novel techniques for analysing microbial diversity in natural and perturbed environmentsV Torsvik
Department of Microbiology, University of Bergen, Norway
J Biotechnol 64:53-62. 1998..Our investigations show that agricultural management, fish farming and pollution may lead to profound changes in the community structure and a reduction in the bacterial diversity...

- Photosynthetic genes in viral populations with a large genomic size range from Norwegian coastal watersRuth Anne Sandaa
Department of Biology, University of Bergen, Bergen, Norway
FEMS Microbiol Ecol 63:2-11. 2008..Alternatively, a picture of diversity based on a different set of biases than that from either isolation-based research or from conventional metagenomic approaches may be observed...
- A multiplex polymerase chain reaction assay for genus-, group- and species-specific detection of mycobacteriaMekonnen Kurabachew
Centre for International Health, University of Bergen, Norway
Diagn Microbiol Infect Dis 49:99-104. 2004..1/oxyRMT-1 was used. When oxyRTB-2.1/oxyRMB-1 primers were used, the 270 bp fragment was obtained for only M. bovis. The assay needed as little as 1 pg of purified genomic DNA to make a positive identification...
- Burden or benefit? Virus-host interactions in the marine environmentRuth Anne Sandaa
Department of Biology, University of Bergen, Post Box 7800, N 5020 Bergen, Norway
Res Microbiol 159:374-81. 2008..We are now beginning to understand the ecological role of viruses in the marine environment. As a result, we believe that viruses have important roles in both biochemical cycling and structuring of marine communities...
- Seasonal variations in virus-host populations in Norwegian coastal waters: focusing on the cyanophage community infecting marine Synechococcus sppRuth Anne Sandaa
University of Bergen, Department of Biology, P O Box 7800, N 5020 Bergen, Norway
Appl Environ Microbiol 72:4610-8. 2006..Our results show that the cyanophage community in Norwegian coastal waters is dynamic and genetically diverse and has a surprisingly wide genomic size range...
