# Metagenomes and metagenome-assembled genomes from a nutrient removal plant at Los Angeles County Sanitation Districts (LACSD) that transitioned from high to low dissolved oxygen

## TL;DR

This paper presents metagenomic data from a wastewater treatment plant that transitioned to low oxygen conditions to reduce energy use.

## Contribution

The study provides new metagenomic datasets and assembled genomes from a wastewater plant under low dissolved oxygen conditions.

## Key findings

- Five metagenomes and 492 MAGs were obtained from the Pomona plant before and after DO reduction.
- The dataset captures microbial community changes during a transition to low DO conditions.

## Abstract

Operating biological nutrient removal (BNR) wastewater treatment plants with low dissolved oxygen (DO) conditions can reduce energy costs. We report on five metagenomes and 492 metagenome-assembled genomes (MAGs) obtained from samples collected at the Pomona water reclamation plant before and after a DO reduction from 3.5 to 0.7 mg/L.
