Article Synopsis
- Pseudomonas sp. ZHL02 utilizes a specific nitrogen removal pathway involving ammonia and various nitrogen compounds to study how it performs heterotrophic nitrification-aerobic denitrification (HNAD).
- The research found that ZHL02 primarily removes ammonia nitrogen through assimilation, with varying effects on electron transport and nitrogen removal based on different carbon sources used, such as sodium succinate and sodium citrate.
- Transcriptome analysis revealed the absence of certain key ammonia-oxidizing genes in ZHL02, suggesting that unknown genes might play a role in its nitrogen removal process, indicating the need for further investigation into the relationship between carbon and nitrogen metabolism in HNAD pathways.
The heterotrophic nitrification-aerobic denitrification (HNAD) process can remove nitrogen and organic carbon under aerobic conditions. To get the in-depth mechanism of the HAND process, a strain named Acinetobacter johnsonii ZHL01 was isolated, and enzyme activity, electron transport, energy production, and gene expression of the strain were studied with small-molecule carbon sources, including sodium citrate, sodium acetate, sodium fumarate, and sodium succinate. The HNAD pathway of ZHL01 was NH→NHOH → NO, and nitrogen balance analysis shows that ZHL01 could assimilate and denitrify 58.
