# Draft genomes of three abundant bacterial isolates from hypersaline Don Juan Pond, Antarctica

## TL;DR

This paper presents draft genomes of three bacteria from a salty Antarctic pond, offering insights into how microbes survive extreme conditions.

## Contribution

The study provides new genomic data from hypersaline Antarctic environments, expanding knowledge of bacterial adaptation.

## Key findings

- Three bacterial isolates from Don Juan Pond were sequenced, representing Bacillota and Pseudomonadota phyla.
- The genomes offer insights into adaptation to hypersalinity, low water activity, and chaotropicity.
- These isolates may represent novel adaptations to extreme environmental conditions.

## Abstract

Calcium chloride-rich brines are extremely rare; thus, microbes inhabiting these systems can provide insight into bacterial adaptation to hypersalinity, low water activity, and chaotropicity. We present the genomes of three bacterial isolates from the sediments of Don Juan Pond, Antarctica, including members of the phyla Bacillota and Pseudomonadota.
