## TL;DR

This paper presents the draft genome of a bacterium that can use nori seaweed as a nutrient source.

## Contribution

The study identifies around 100 genes involved in polysaccharide degradation in Agarivorans albus strain S3.

## Key findings

- The genome contains genes for degrading starch, β-glucans, and other polysaccharides.
- Agarivorans albus strain S3 can utilize agar and porphyran from nori seaweed.
- The bacterium has a diverse set of enzymes for breaking down complex carbohydrates.

## Abstract

We sequenced the draft genome of Agarivorans albus strain S3, a bacterium capable of utilizing nori (Pyropia yezoensis), a polysaccharide-rich seaweed, as a nutrient source. The genome revealed approximately 100 genes involved in the degradation of starch, β-glucans including cellulose, galactans including agar/porphyran, mannans, xylan, and other polysaccharides.
