On the carbon source of anaerobic ammonia oxidation

The process of anaerobic ammonia oxidation is of great significance to microbial metabolism, and carbon sources play a key role in this process. Appropriate carbon sources are the cornerstone of ensuring the activity and functional stability of anaerobic ammonia oxidation flora.

In the anaerobic ammonia oxidation system, carbon sources are not only related to the growth and reproduction of microorganisms, but also have a profound impact on the reaction path and product generation. High-quality carbon sources can provide the necessary energy and substances for the flora to successfully complete metabolic activities. For example, some organic carbon sources that are easy to be used can accelerate the uptake and transformation of substrates by anaerobic ammonia oxidizers and improve the reaction efficiency.

However, the selection and regulation of carbon sources is not easy. There are many types of carbon sources with different characteristics. If the concentration of the carbon source is too high, it may cause the overgrowth of heterotrophic bacteria, compete with the anaerobic ammonia oxidizing bacteria for substrates and living space, and disrupt the system balance; if the concentration is too low, it cannot meet the demand of the anaerobic ammonia oxidizing bacteria, resulting in reduced activity and affecting treatment efficiency.

Therefore, accurately control the anaerobic ammonia oxidizing carbon sources, in-depth understanding of the mechanism of action of different carbon sources on the anaerobic ammonia oxidation process, and rationally select and regulate the carbon sources according to the actual conditions of the system, which is the key to achieving efficient and stable anaerobic ammonia oxidation reaction, and is also of great significance to related engineering applications and
