chlorate respiration

traitmech:000198 · CLASS · PROPOSED

An anaerobic respiration in which an organism uses chlorate as the terminal electron acceptor and reduces it to chloride for energy conservation.

chlorate ion as the sole electron acceptor for oxidation of organic matter in a previously unknown mode of respiration

Danielsson Thorell et al. support the organism-level respiratory use of chlorate as the electron acceptor.
DOI:10.1128/AEM.69.9.5585-5592.2003
reduction of chlorate occurs in a two-step reaction: chlorate reduction followed by chlorite decomposition

The Ideonella dechloratans chlorate pathway reduces chlorate and then decomposes the chlorite intermediate.
DOI:10.1128/AEM.07303-11
Perchlorate-respiring bacteria (PRB) can use both perchlorate and chlorate as terminal electron acceptors, whereas chlorate-respiring bacteria (CRB) use only chlorate

Hellberg Lindqvist et al. separate chlorate-respiring bacteria from broader perchlorate reducers.

CURATION TODO OPEN chlorate-respiration-xref-gap · raised by codex · 2026-09-15

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

The pinned METPO snapshot contains only the obsolete broad (Per)chlorate respiration class and no active exact organism-level chlorate respiration class. Candidate EC, Rhea, and protein-family terms for chlorate reductase or chlorite dismutase are narrower than the whole-organism anaerobic respiration phenotype.

Minted chlorate respiration as a DOI-backed anaerobic respiration TraitRecord with a related synonym after a repository-wide duplicate review covering ignored and hidden files; the local METPO snapshot has only an obsolete broad (Per)chlorate respiration class and the replacement placeholder is reserved in proposals/metpo_traitmech_v75.
