# Archaeal genomes linked to industrial wastewater and associated freshwater in South Africa

## TL;DR

This study identifies archaeal genomes in South African industrial wastewater and rivers, highlighting their role in degrading heavy metals.

## Contribution

The study presents novel archaeal genomes from understudied South African environments and identifies genes involved in heavy metal degradation.

## Key findings

- Archaeal genomes were recovered from South African wastewater treatment plants and associated rivers.
- Functional analysis identified genes involved in heavy metal degradation, suggesting a role in contaminant breakdown.

## Abstract

Archaea provide important ecosystem services including the degradation of contaminants. Here, we present archaeal genomes from understudied South African wastewater treatment plants (WWTPs) and associated rivers receiving industrial effluents. Functional analysis revealed key genes implicated in heavy metal degradation, offering a valuable resource for mechanistic studies on archaeal metabolism.
