## TL;DR

This paper presents the complete genome of a marine bacterium that can grow on a polyolefin model compound, offering insights into how bacteria colonize plastic surfaces in the ocean.

## Contribution

The study provides the first complete genome sequence of Alteromonas stellipolaris strain 6L2 isolated using a polyolefin model substrate.

## Key findings

- The genome includes a circular chromosome and a plasmid.
- The genome reveals genetic potential for polyolefin surface colonization in marine environments.

## Abstract

Alteromonas stellipolaris strain 6L2 was isolated from surface seawater via enrichment culture using an ethylene-α-olefin co-oligomer, a polyolefin model substrate, as sole carbon source. We report its complete genome sequence comprising a circular chromosome and a plasmid. The genome provides insights into bacterial colonization of polyolefin surfaces in marine environments.
