According to Casey Bryce, by the research team's calculations iron oxidation by nitrate-reducing bacteria may have initially compensated for the reduced contribution of phototrophic iron oxidizers.

Scientists trick iron-eating bacteria into breathing electrons instead Date: January 29, 2013 Source: American Society for Microbiology Summary: Scientists have developed a way to grow iron ...

Some of these bacteria use iron oxide as their electron acceptor. On the flip side, some other microbes receive electrons donated by other iron compounds. In both cases, ...

Normally, to grow and reproduce, it lifts electrons off of a form of dissolved iron called Fe (II), also known as iron (II) oxide. This turns it into a solid precipitate of Fe(III) (iron (III) oxide).

How 'Iron Man' bacteria could help protect the environment. ... and they can power themselves by pulling energy from minerals containing iron oxide. "They respire rust," Reguera said.

In this case, the laser beam measures the amount of attraction between the bacteria and the iron oxide. Click here for a larger version of this image. "Also, there's ...

A new treatment could help, as it uses tiny particles known as nanozymes to break down plaque and kill cavity-causing bacteria. For people with particularly cavity-prone teeth, daily brushing and ...

This habitat also happens to have iron oxide minerals coating the sandstone grains, ... “There have been some iron-reducers [bacteria] found at deep subsurface environments,” Sanford said.

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, ...

Scientists think these bacteria must carry out the iron oxidation step on their surfaces. If that’s true, Bond reasoned, ...
