Fermentation allows for the recycling of hydrogen and the production of atp under conditions.

The answer is Anaerobic.

Explanation:

Fermentation allows for the recycling of hydrogen and the production of ATP under anaerobic conditions. The fermentation doesn't require oxygen and it allows an organism to obtain energy getting a product (ethanol or lactate). It happens, for example, in the muscles when the energy levels are not enough.
