Electron donor

It is a reducing agent that, by virtue of its donating electrons, is itself oxidized in the process.

An obsolete definition equated an electron donor and a Lewis base.

This leads to the formation of charge transfer complexes, in which the components largely retain their chemical identities.

Microorganisms, such as bacteria, obtain energy in electron transfer processes.

When clean-up professionals use monitored natural attenuation to clean up contaminated sites, biodegradation is one of the major contributing processes.
