SAR11 is a group of small, carbon-oxidizing bacteria that reach a global estimated
population size of 2.4× 1028 cells—approximately 25% of all plankton. They are found …

Microbes exist in a range of metabolic states (for example, dormant, active and growing) and
analysis of ribosomal RNA (rRNA) is frequently employed to identify the 'active'fraction of …

In marine sediments, DNA occurs both inside and outside living organisms. DNA not
enclosed in living cells may account for the largest fraction of total DNA, and include …

The surface layer of the oceans and other aquatic environments contains many bacteria that
range in activity, from dormant cells to those with high rates of metabolism. However, little …

Very little is known about growth rates of individual bacterial taxa and how they respond to
environmental flux. Here, we characterized bacterial community diversity, structure and the …

One of soil microbiology's most intriguing puzzles is how so many different bacterial species
can coexist in small volumes of soil when competition theory predicts that less competitive …

Significant effort is currently focused on microbial fuel cells (MFCs) as a source of renewable
energy. Most studies concentrate on operation at mesophilic temperatures. However …

There is growing evidence that dissolved phosphorus can regulate planktonic production in
the oceans' subtropical gyres, yet there is little quantitative information about the …

We determined the compositions of bacterioplankton communities in surface waters of
coastal California using clone libraries of 16S rRNA genes and fluorescence in situ …

Fluorescence in situ hybridization (FISH) is widely used to describe bacterial community
composition and, to a lesser extent, to describe the physiological state of cells. One of the …
