## TL;DR

This paper presents the draft genomes of six new bacteria that can break down the biodegradable plastic PHB, isolated from marine environments.

## Contribution

The novelty lies in identifying and sequencing six phylogenetically distinct PHB-degrading bacterial strains.

## Key findings

- The six bacterial strains have genome sizes ranging from 4.5 to 6.6 Mb.
- These strains are phylogenetically distinct from previously known PHB-degrading bacteria.
- They were isolated from marine samples undergoing PHB biodegradation tests.

## Abstract

The draft genome sequences of six strains of bacteria degrading polyhydroxybutyrate (PHB), a biodegradable plastic, have been sequenced. These strains were isolated from marine biodegradation test samples of PHB. The genome sizes range from 4.5 to 6.6 Mb, and they are phylogenetically distinct from known PHB-degrading bacteria.
