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 …

Dysoxic marine waters (DMW,< 1 μM oxygen) are currently expanding in volume in the
oceans, which has biogeochemical, ecological and societal consequences on a global …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

Deep-sea hydrothermal-vent ecosystems have stimulated decades of scientific research and
hold promise of mineral and genetic resources that also serve societal needs. Some …

Ion-selective membrane electrodes (ISEs) have become very attractive sensing platforms for
environmental water analysis. This review mainly presents recent advances in polymeric …

The thermodynamics for the first electron transfer step for sulfide and oxygen indicates that
the reaction is unfavorable as unstable superoxide and bisulfide radical ions would need to …

O presente trabalho apresenta uma abordagem simples e didática sobre conceitos

The methods used until now have not been able to reliably resolve O2 concentrations in
oceanic oxygen minimum zones below 1–2 µmol L− 1. We present a new amperometric …

Microbes form mats with architectures that promote efficient metabolism within a particular
physicochemical environment, thus studying mat structure helps us understand …

Sulfur plays a pivotal role in interactions within the atmosphere, lithosphere, pedosphere,
hydrosphere and biosphere, and the functioning of living organisms. In the Earth's crust …
