## TL;DR

Scientists sequenced the genome of a new Rhodococcus pyridinivorans strain that can break down aniline, a toxic chemical.

## Contribution

The complete genome and annotation of key aniline-degrading enzymes in Rhodococcus pyridinivorans FL1 are newly reported.

## Key findings

- Rhodococcus pyridinivorans FL1 was isolated from a malodorous urban river and degrades aniline.
- The complete genome sequence was determined and key enzymes like catA were annotated.
- The study identifies enzymes involved in the aniline degradation pathway.

## Abstract

A novel Rhodococcus pyridinivorans strain FL1, capable of degrading aniline, was isolated from an urban river ecosystem. The complete genome sequence of this strain was presented, and the key enzymes involved in the aniline degradation pathway, including catechol 1,2-dioxygenase (catA) and 3-carboxy-cis,cis-muconate cycloisomerase, were systematically annotated‌.
