Journal ArticleDOI
Significance of size and nucleic acid content heterogeneity as measured by flow cytometry in natural planktonic bacteria.
TL;DR: In various experiments where predator pressure on bacteria had been reduced, the percentage contribution of HDNA bacteria to total bacterial numbers (%HDNA) increased, such that theHDNA bacteria are the dynamic members of the bacterial assemblage.
Journal ArticleDOI
Global patterns of diversity and community structure in marine bacterioplankton
Thomas Pommier,Björn Canbäck,Lasse Riemann,Kjärstin H Boström,Karin Simu,Per Lundberg,Anders Tunlid,Åke Hagström +7 more
TL;DR: In this paper, the authors examined marine bacterioplankton communities from coastal waters at nine locations distributed world-wide using a comprehensive clone library of 16S ribosomal RNA genes, used as operational taxonomic units (OTU).
Journal ArticleDOI
Fractionated phytoplankton primary production, exudate release and bacterial production in a Baltic eutrophication gradient
Ulf Larsson,Åke Hagström +1 more
TL;DR: It was demonstrated that selective filtration does not quantitatively separate photoautotrophs and bacteria in the northern Baltic proper and in the eutrophicated area.
Journal ArticleDOI
Total counts of marine bacteria include a large fraction of non-nucleoid-containing bacteria (ghosts).
Ulla Li Zweifel,Åke Hagström +1 more
TL;DR: In samples from the Baltic Sea, the North Sea, and the northeastern Mediterranean Sea, it is found that only a minor fraction of total counts can be scored as bacteria with nucleoids; therefore, a much lower number of bacteria that grow at rates higher than those previously estimated must be responsible for the measured bacterial production in these seas.
Journal ArticleDOI
Consumption of dissolved organic carbon by marine bacteria and demand for inorganic nutrients
TL;DR: Consumption of dissolved organic carbon by marine bacteria and demand for inorganic nutrients is studied in this article, where the authors propose a method to solve the problem of inorganic carbon depletion.
