# Draft genome sequence of Bacillus velezensis strain 3TSA-3, a potential probiotic for Pacific white shrimp Penaeus vannamei postlarvae isolated from commercial hatchery tanks

## TL;DR

This paper presents the genome of a Bacillus strain that could act as a probiotic for shrimp larvae in aquaculture.

## Contribution

The study provides a draft genome of a Bacillus velezensis strain with probiotic potential for shrimp hatcheries.

## Key findings

- The strain 3TSA-3 lacks virulence genes and contains bacteriocin-encoding genes.
- It was isolated from a hatchery with high shrimp survival despite Vibrio presence.

## Abstract

We report the draft genome of Bacillus velezensis strain 3TSA-3, isolated from Pacific white shrimp Penaeus vannamei postlarvae collected from a hatchery tank with high survival despite the presence of pathogenic Vibrio. The strain possesses genes encoding bacteriocins and lacks virulence factor genes, characteristics for a potential aquaculture probiotic.
