Summary 16S rRNA-targeted oligonucleotide probes for eubacteria (EUB338), ammonium-
oxidizing bacteria (Nsm156) and nitrite-oxidizing bacteria (Nb1000) were used for the rapid …

▪ Abstract Since the delineation of 12 bacterial phyla by comparative phylogenetic analyses
of 16S ribosomal RNA in 1987 knowledge of microbial diversity has expanded dramatically …

The evolution of marine microbes over billions of years predicts that the composition of
microbial communities should be much greater than the published estimates of a few …

Microbial communities are vital in the functioning of all ecosystems; however, most
microorganisms are uncultivated, and their roles in natural systems are unclear. Here, using …

The respiratory activities of plant roots, of their mycorrhizal fungi and of the free-living
microbial heterotrophs (decomposers) in soils are significant components of the global …

The dissolution of sulfide minerals such as pyrite (FeS2), arsenopyrite (FeAsS), chalcopyrite
(CuFeS2), sphalerite (ZnS), and marcasite (FeS2) yields hot, sulfuric acid-rich solutions that …

▪ Abstract Uncultured microorganisms comprise the majority of the planet's biological
diversity. Microorganisms represent two of the three domains of life and contain vast …

Microbial life predominates in the ocean, yet little is known about its genomic variability,
especially along the depth continuum. We report here genomic analyses of planktonic …

Ecosystems are shaped by complex communities of mostly unculturable microbes.
Metagenomes provide a fragmented view of such communities, but the ecosystem functions …

Microbial diversity studies based on the cloning and sequencing of DNA from nature support
the conclusion that only a fraction of the microbial diversity is currently represented in culture …
