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.

So the very oldest banded iron formations cannot be the result of O 2-dependent oxidation. In 1993, bacteria were discovered which do not need oxygen but can oxidize Fe(II) by using energy from ...

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 ...

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).

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 ...

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.

Iron-oxidizing bacteria (FeOB) have been detected in a wide variety of environments and have been shown to increase the rate of iron oxidation by up to four orders of magnitude compared with the ...

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 ...

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, ...
