Omnitrophica or Omnitrophota is a proposed candidate phylum of bacteria[1] with chemolithoautotrophic nutrition. It was previously known as candidate phylum OP3. These bacteria appear to thrive in anoxic environments, such as deep marine sediments, hypersaline environments, freshwater lakes, aquifers, flooded soils, and methanogenic bioreactors.[2] Genomic analyzes have found genes responsible for the construction of magnetosomes, which are also present in other phyla of bacteria. These organelles have magnetic properties, which causes bacteria to orient themselves magnetically in the environment.[3] Omnitrophica is part of the PVC superphylum along with the phyla Planctomycetota, Verrucomicrobiota and Chlamydiota with which it shares a common ancestor.[4]
