## TL;DR

This paper reports the full genome sequence of a carotenoid-producing bacterium from a brackish water lake in Indonesia.

## Contribution

The study provides a new genome sequence and identifies genes related to halophilic traits and carotenoid production.

## Key findings

- The genome is 4.1 Mb in size and provides insights into the bacterium's taxonomic position.
- Genes associated with halophilic properties and orange pigmentation were identified.

## Abstract

Halobacillus sp. 12SKB was isolated from a unique Indonesian brackish water lake ecosystem, and its genome sequence was determined. Here, we report its 4.1-Mb genome, which gives insight into the taxonomic position and the secondary metabolite production capacity and reveals genes putatively responsible for its halophilic properties and orange occurrence.

## Linked entities
