    • Comparative analysis of HiSeq3000 and BGISEQ-500 sequencing platform with shotgun metagenomic sequencing data 

      Kumar, Animesh; Robertsen, Espen Mikal; Willassen, Nils Peder; Fu, Juan; Hjerde, Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-29)
      Recent advances in sequencing technologies and platforms have enabled to generate metagenomics sequences using different sequencing platforms. In this study, we analyzed and compared shotgun metagenomic sequences generated by HiSeq3000 and BGISEQ-500 platforms from 12 sediment samples collected across the Norwegian coast. Metagenomics DNA sequences were normalized to an equal number of bases for ...

      Evaluating metagenomic software is key for optimizing metagenome interpretation and focus of the Initiative for the Critical Assessment of Metagenome Interpretation (CAMI). The CAMI II challenge engaged the community to assess methods on realistic and complex datasets with long- and short-read sequences, created computationally from around 1,700 new and known genomes, as well as 600 new plasmids ...

    • The immediate global responses of Aliivibrio salmonicida to iron limitations 

      Thode, Sunniva Katharina; Kahlke, Tim; Robertsen, Espen Mikal; Hansen, Hilde; Haugen, Peik (Journal article; Tidsskriftartikkel, 2015-02-04)
      <i>Background</i>: Iron is an essential micronutrient for all living organisms, and virulence and sequestration of iron in pathogenic bacteria are believed to be correlated. As a defence mechanism, potential hosts therefore keep the level of free iron inside the body to a minimum. In general, iron metabolism is well studied for some bacteria (mostly human or animal pathogens). However, this area ...

    • META-pipe – Distributed Pipeline Analysis of Marine Metagenomic Sequence Data 

      Robertsen, Espen Mikal (Doctoral thesis; Doktorgradsavhandling, 2017-05-19)
      With the accelerated advances in sequencing technology the last decade, the field of metagenomics has progressed immensely. Sampling and sequencing of metagenomic data is now prevalent, and publicly available data sets from mundane soil and water environments to exotic niche habitats such as geothermal hot springs are readily available through sequence data repositories such as the European Nucleotide ...

    • Viral assemblage variation in an Arctic shelf seafloor 

      Nguyen, Tan Thi; Robertsen, Espen Mikal; Landfald, Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-09)
      Spatial differences in microbial communities are observable even in habitats with moderate environmental variation, such as within the pelagic zone or seafloor of geographically finite regions of the oceans. Here we explore whether biogeographical variations are also manifested at this level in the structure of viral assemblages by comparing DNA viromes from the Barents Sea upper seafloor, collected ...
