A positive voltage means that the system is capable of attracting electrons, thus indicative of an oxidizing condition while a negative voltage means a reducing condition exists. As oxygen is a ...

Researchers studied ancient iron-oxidizing bacteria to understand their role in Earth's early iron formations. The study found that nitrate-reducing bacteria produced toxic nitrogen monoxide, ...
