# Draft genome sequence of Polaribacter sp. strain OB-PA-B3: a novel algal polysaccharide degrader isolated from the particle-associated fraction of Osaka Bay, Japan

## TL;DR

Scientists sequenced the genome of a new Polaribacter strain that breaks down algal polysaccharides, isolated from Osaka Bay, Japan.

## Contribution

The paper presents the draft genome of a novel algal polysaccharide-degrading Polaribacter strain.

## Key findings

- The genome has 91.9% ANI to Polaribacter sp. BM10.
- The 3.2 Mbp genome includes enzymes for laminarin utilization.
- The strain was isolated from the particle-associated fraction of seawater.

## Abstract

A novel, algal polysaccharide-degrading Polaribacter strain, OB-PA-B3, was isolated from seawater in Osaka Bay, Japan. The genome sequence showed the highest average nucleotide identity (ANI) (91.9%) to Polaribacter sp. BM10 among available genomes. The 3.2 Mbp draft genome (29.8% guanine-cytosine [GC]) encodes carbohydrate-active enzymes (CAZymes), including a laminarin-utilizing enzyme.
