## TL;DR

This paper presents the complete genome sequence of Megasphaera sueciensis, a beer spoilage bacterium that causes off-flavors and cloudiness in beer.

## Contribution

The study provides the first complete and circular genome sequence of Megasphaera sueciensis DSM 17042.

## Key findings

- The genome is 2.9 Mbp in size and contains 2,696 predicted coding sequences.
- The genome sequence will aid in understanding the bacterium's role in beer spoilage.

## Abstract

Megasphaera sueciensis is an obligate anaerobic, gram-negative beer spoilage bacterium causing unwanted off-flavors and turbidity. Here we report the complete and circular genome of 2.9 Mbp with 2,696 predicted coding sequences of the type strain Megasphaera sueciensis DSM 17042.
