The use of anammox microbiomes to treat wastewater is an escalating biotechnology, yet the functional role heterotrophic bacteria play in these systems remains poorly understood. Here, Lawsonet al. use metagenomics and metatranscriptomics to reveal that heterotrophs degrade free peptides, while recycling nitrate to nitrite.
