Community composition of the marine bacterioplankton in Kongsfjorden (Spitsbergen) as revealed by 16S rRNA gene analysis
Phylogenetic diversity of the marine bacterioplankton in Kongsfjorden (Spitsbergen) was investigated by 16S rRNA gene analysis.

Phylogenetic diversity of the marine bacterioplankton in Kongsfjorden (Spitsbergen) was investigated by 16S rRNA gene analysis. Community fingerprint analysis by PCR-denaturing gradient gel electrophoresis revealed that there was no apparent difference of bacterioplankton community composition between sampling locations in the fjord. A higher biodiversity was observed in bottom water of station 3 in the central part of the fjord. By 16S rRNA gene clone library analysis, sequences detected both in surface and bottom water of station 3 fell into eight putative divisions, including Proteobacteria (Alpha, Beta, Gamma and Delta), Bacteroidetes, Actinobacteria, Verrucomicrobia and unidentified bacteria, in addition to chloroplasts of algae.
