Members of the diverse bacterial phylum Bacteroidetes have colonized virtually all types of
habitats on Earth. They are among the major members of the microbiota of animals …

The finding that total viral abundance is higher than total prokaryotic abundance and that a
significant fraction of the prokaryotic community is infected with phages in aquatic systems …

Phytoplankton blooms characterize temperate ocean margin zones in spring. We
investigated the bacterioplankton response to a diatom bloom in the North Sea and …

Background Marine microbial communities have been essential contributors to global
biomass, nutrient cycling, and biodiversity since the early history of Earth, but so far their …

Culture-dependent and-independent studies have found that prokaryotic assemblages are
quite diverse in aquatic habitats and contain representatives of virtually all of the roughly 40 …

Hundreds of millions of litres of petroleum enter the environment from both natural and
anthropogenic sources every year. The input from natural marine oil seeps alone would be …

We used a method that combines microautoradiography with hybridization of fluorescent
rRNA-targeted oligonucleotide probes to whole cells (MICRO-FISH) to test the hypothesis …

Viruses can influence the genetic diversity of prokaryotes in various ways. They can affect
the community composition of prokaryotes by 'killing the winner'and keeping in check …

Heterotrophic marine bacteria play key roles in remineralizing organic matter generated
from primary production. However, far more is known about which groups are dominant than …

Bacterial community composition, enzymatic activities, and carbon dynamics were examined
during diatom blooms in four 200-liter laboratory seawater mesocosms. The objective was to …
