One that binds up oxygen in the water to create an anaerobic environment.

These sediments then provide an anaerobic environment which protects from further degradation.

Since Apollo's energy derives entirely from the sun, he can survive in anaerobic environments indefinitely.

When plants die in such an anaerobic aquatic environment, low oxygen levels prevent their complete bacterial decay.

In these anaerobic environments, protozoa break down plant cellulose to obtain energy.

Gas-pak is a method used in production of an anaerobic environment.

The fermentation is carried out in an anaerobic environment.

Adler realized that the creation of anaerobic environments could be produced on a mass scale.

But these species of yeast will produce ethanol only in an anaerobic environment (not cellular respiration).

Fermentation does not necessarily have to be carried out in an anaerobic environment.
