Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

This paper reviews dissimilatory nitrate reduction to ammonium (DNRA) in soils-a newly
appreciated pathway of nitrogen (N) cycling in the terrestrial ecosystems. The reduction of …

Cells of most bacterial species are around 2 micrometers in length, with some of the largest
specimens reaching 750 micrometers. Using fluorescence, x-ray, and electron microscopy in …

The profound influence of microorganisms on human life and global biogeochemical cycles
underlines the value of studying the biogeography of microorganisms, exploring microbial …

Revealing the biogeographies and ecologies of rare and abundant microorganisms is
crucial to understand ecosystem diversity and function. In this study, we investigated the …

The~ 1.6 Ga Tirohan Dolomite of the Lower Vindhyan in central India contains phosphatized
stromatolitic microbialites. We report from there uniquely well-preserved fossils interpreted …

The majority of life on Earth—notably, microbial life—occurs in places that do not receive
sunlight, with the habitats of the oceans being the largest of these reservoirs. Sunlight …

Many wastewater treatment plants in the world do not remove reactive nitrogen from
wastewater prior to release into the environment. Excess reactive nitrogen not only has a …

Why do bacteria have shape? Is morphology valuable or just a trivial secondary
characteristic? Why should bacteria have one shape instead of another? Three broad …

Coastal hypoxia (defined here as< 1.42 ml L− 1; 62.5 μM; 2 mg L− 1, approx. 30% oxygen
saturation) develops seasonally in many estuaries, fjords, and along open coasts as a result …
