Brocadia
candidate of bacteria
"Candidatus Brocadia" is a candidatus genus of bacteria, meaning that while it is well-characterized, it has not been grown as a pure culture yet. Due to this, much of what is known about Candidatus species (including Brocadia) has been discovered using culture-independent techniques such as metagenomic sequence analysis.
Some notable species within this genus include the type species, Candidatus Brocadia anammoxidans, along with Candidatus Brocadia sinica and Candidatus Brocadia fulgida. Many of the species in this genus, including those already listed, are capable of anaerobic ammonium oxidation, also known as anammox, an important part of the global nitrogen cycle. Anammox works by converting fixed nitrogen back into N2 gas in the atmosphere. Anammox bacteria have a unique, membrane-bound organelle where this anammox process takes place—it is called the anammoxosome.
Phylogeny
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI). Phylogeny based on 120 marker proteins GTDB 10-RS226.
Structure
Candidatus Brocadia falls under the phylum of Planctomycetota. These bacteria are known for a few distinguishing phenotypic features including cell surface pits (crateriform structures), no present peptidoglycan in the cell wall, compartmentalization, and even budding reproduction rather than binary fission.
The public source identifies “Brocadia” as candidate of bacteria. This brief keeps that definition visible, then builds a research path around Brocadia, candidate and bacteria.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Brocadia”, the useful work is to connect “candidate of bacteria” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q12062662. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
