## TL;DR

This paper reports the complete genome sequence of a new bacterium that can remove nitrogen from sewage and degrade harmful compounds.

## Contribution

The study provides the first complete genome sequence of Stutzerimonas kunmingensis L4, a novel HNAD bacterium.

## Key findings

- The genome includes genes for heterotrophic nitrification and aerobic denitrification.
- It also contains genes for degrading aromatic compounds.
- The genome is 4.66 million base pairs long with a GC content of 62.64%.

## Abstract

We present the complete genome of Stutzerimonas kunmingensis L4, isolated from sewage sludge. The genome consists of a circular chromosome (4,661,724 bp) with a GC content of 62.64%, containing several Heterotrophic Nitrification-Aerobic Denitrification (HNAD) and aromatic compound degradation genes.
