Question

Why is gas production not recognized as nitrate reduction?

Answer 1

Gas production is not recognized as nitrate reduction because they refer to different processes in biology.

Step-by-step explanation:

Gas production is not recognized as nitrate reduction because nitrate reduction refers to the process of converting nitrate (NO3) to nitrite (NO2) and then to nitrogen gas (N2) by bacteria in anoxic environments. This process is part of denitrification, which occurs in the nitrogen cycle. Gas production, on the other hand, can refer to the production of gases like carbon dioxide (CO2) or methane (CH4) through different biological or chemical processes.

Answer 2

The gas production not recognized as nitrate reduction is because organisms that can ferment also produce gas. Therefore even if gas is produced on the tube, you can't tell if it's by fermentation or by nitrate reduction. I hope the answer helps.
