Brocadia fulgida
species of bacterium
Candidatus Brocadia fulgida is an anammox bacterial species commonly found in wastewater sludge. Anaerobic ammonium oxidation, or anammox, is the bacterial metabolic strategy where nitrogen gas is produced in anoxic conditions, meaning no oxygen, through the metabolism of ammonium and nitrate or nitrite. Anammox metabolism is rare in nature and was only discovered in 1995. Though only a few anammox species have been identified, with estimates ranging from 23-27 species, these nitrogen-producing microbes are responsible for over 50% of Earth's atmospheric nitrogen. Ca. B. fulgida is able to be cultured, a property unique to fewer than 1% of microbial species. Candidatus refers to microbes that are well characterized, but have not been maintained in pure culture. Ca. B. fulgida is also the only known anammox species that can fluoresce.
Phylogeny
Within the Planctomyces phylum are the four other genera associated with anammox species: Ca.
The public source identifies “Brocadia fulgida” as species of bacterium. This brief keeps that definition visible, then builds a research path around Brocadia, fulgida and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Brocadia fulgida”, the useful work is to connect “species of bacterium” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q16954038. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
