We applied nucleic acid-based molecular methods, combined with estimates of biomass (ATP),
pigments, and microelectrode measurements of chemical gradients, to map microbial …

We report for the first time micrometer-scale correlation of geologic and microbial processes
in modern marine stromatolites. Precipitation of micritic laminae in these stromatolites was …

Microbial mats on the surfaces of modern, marine stromatolites at Highborne Cay, Bahamas,
were investigated to assess the role of microbial processes in stromatolite formation. The …

The advent of oxygenic photosynthesis on Earth may have increased global biological
productivity by a factor of 100–1,000 (ref. 1 ), profoundly affecting both geochemical and …

Exposure to moderate doses of UV B (0.35 to 0.79 W m(sup-2) s(sup-1) or 0.98 to 2.2 (mu)mol
of photons m(sup-2) s(sup-1) at 310 nm) caused the surface layers of microbial mats from …

Continental shelf sediments of the central Chile upwelling area are dominated by the
presence of dense mats of the filamentous, sulfur-depositing bacterium Thioploca spp. We …

To investigate the extent of genetic stratification in structured microbial communities, we
compared the metagenomes of 10 successive layers of a phylogenetically complex hypersaline …

Cyanobacterial organic matter excretion is crucial to carbon cycling in many microbial
communities, but the nature and bioavailability of this C depend on unknown physiological …

Metagenomic sequence data from defined mock communities is crucial for the assessment
of sequencing platform performance and downstream analyses, including assembly, binning …

Remote effects (occurring without physical contact) of two plant growth-promoting bacteria (PGPB)
Azospirillum brasilense Cd and Bacilus pumilus ES4 on growth of the green …
