## TL;DR

This paper explores microbial communities in bioreactors that convert dairy waste into lactic acid, identifying 42 unique genomes.

## Contribution

The study provides new metagenome-assembled genomes from anaerobic bioreactors processing dairy residues.

## Key findings

- Forty-two unique metagenome-assembled genomes were identified from four anaerobic bioreactors.
- The genomes represent distinct microbial taxa involved in fermenting dairy residues into lactic acid.

## Abstract

To advance the knowledge of microbial communities capable of fermenting agro-industrial residues into value-added products, we report metagenomes of microbial communities from four anaerobic bioreactors fed a mixture of ultra-filtered milk permeate and cottage cheese acid whey. This analysis produced 42 unique metagenome-assembled genomes (MAGs) that represent distinct taxa.
