"Omnitrophica" or "Omnitrophota" is a candidate phylum of bacteriaGenome database. Omnitrophota 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.Glöckner, Jana, et al. Phylogenetic diversity and metagenomics of candidate division OP3. Environmental microbiology 12.5 (2010): 1218-1229. 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.Kolinko, Sebastian, et al. Single‐cell genomics of uncultivated deep‐branching magnetotactic bacteria reveals a conserved set of magnetosome genes. Environmental microbiology 18.1 (2016): 21-37. Omnitrophica is part of the "PVC" superphylum along with the phyla Planctomycetota, Verrucomicrobiota and Chlamydiota with which it shares a common ancestor.Spring, Stefan, et al. Characterization of the first cultured representative of Verrucomicrobia subdivision 5 indicates the proposal of a novel phylum. The ISME journal (2016).
Classification The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).
