Candidatus Brocadia fulgida is a bacterial species that performs the anammox process. Fatty acids constitute an enrichment culture for B. fulgida. The species' 16S ribosomal RNA sequence has been determined. During the anammox process, it oxidizes acetate at the highest rate and out-competes other anammox bacteria which indicates that it doesn't incorporate acetate directly into their biomass like other anammox bacteria.
