## TL;DR

This paper presents the genome sequence of a salt-tolerant bacteria that can produce PHA, a useful bioplastic.

## Contribution

The novel contribution is the complete genome sequence of Bacillus swezeyi SDB04, a PHA-producing strain from a hypersaline environment.

## Key findings

- The genome of Bacillus swezeyi SDB04 was sequenced and assembled with an estimated chromosome size of 4.29 Mb.
- The strain can produce Polyhydroxyalkanoates (PHA) under high salt conditions.
- The genomic data may aid in improving efficient PHA production processes.

## Abstract

We report the complete genome sequence of Bacillus swezeyi SDB04, which was isolated from a hypersaline environment and could produce Polyhydroxyalkanoates (PHA). The de novo assembly resulted in an estimated chromosome size of 4.29 Mb. Genomic sequence information will help to develop the potential for efficient PHA production.
