A long-term domesticated non-Dehalogenimonas synergistic consortium optimized for bioremediation of 1,2,3-trichloropropane (TCP) in groundwater. The PubMed abstract reports complete TCP removal within 3.5 days after co-metabolic substrate stimulation, links the transformation to a Fusibacter, Desulfovibrio, Nitratidesulfovibrio, and Parabacteroides alliance, and describes a coupled metabolic module involving hydrogen production, cofactor synthesis, and reductive dechlorination.

Ecological Interactions
The graph shows only explicitly linked interaction participants. Community members without an asserted participant link are omitted; membership alone does not imply an interaction.
Inferred Hydrogen Cofactor Reductive-Dechlorination Module
HYPOTHESIZED functional coupling: community and metagenomic analyses associate the four named genera with hydrogen production, cofactor synthesis and reductive dechlorination. This is a consortium-level reconstruction, not measured intergenus hydrogen/cofactor transfer or a demonstrated genus-specific dechlorination pathway.
Participating Taxa: Fusibacter, Desulfovibrio, Nitratidesulfovibrio, Parabacteroides
Metabolites: hydrogen (CHEBI:18276 · MediaIngredientMech · CMMMech), 1,2,3-trichloropropane (CHEBI:34036 · MediaIngredientMech · CMMMech)
Biological Processes:
- halogenated hydrocarbon metabolic process (GO:0042197 · PathwayMech)
Evidence

Co-Metabolic Substrate Enhanced TCP Removal
Sodium acetate and lactate amendments enhanced TCP degradation in the domesticated consortium. The abstract reports an overall average degradation rate of 19.06 umol L-1 d-1 and complete removal within 3.5 days; those values are not separately assigned to each amendment or to an individual genus.
Participating Taxa: Fusibacter, Desulfovibrio, Nitratidesulfovibrio, Parabacteroides

Knowledge gaps & discussions (2)
KNOWLEDGE_GAP OPEN Resolve species or strain IDs, initial inoculum source, the directed domestication passaging regimen, quantitative member abundances, co-metabolic substrate concentrations, and genus-specific assignment of hydrogen-production, cofactor-synthesis, and reductive-dechlorination roles.
The accessible PubMed abstract names the four-genera consortium and overall hydrogen/cofactor/reductive-dechlorination module, but it does not expose species or strain IDs, original inoculum details, full medium composition, substrate concentrations, transfer cadence, or the role of each named genus within the module.

KNOWLEDGE_GAP OPEN Which inferred functions actually mediate the observed amendment response?
Positive substrate-amendment effects remain distinct from metagenome-inferred coupling. The retrieved abstract does not resolve intergenus transfer, necessary cofactors or functional perturbations; the publisher full text was not retrieved. Keep the two existing nodes without inventing a module-to-removal arrow. Prior removal of syntrophy assertions and dangling phenotype arrows is preserved.

realized through a coupled metabolic module of "hydrogen production, cofactor synthesis, and reductive dechlorination"
The abstract attributes this coupled module to community and metagenomic analyses; it does not independently demonstrate transfer or assign each function to a named genus.
