AHL-mediated interspecific communication under disturbance

The disturbed aerobic-denitrification SMC primarily uses C4-HSL and 3OC12-HSL acyl-homoserine-lactones for interspecific communication.

Participating Taxa: Pseudomonas aeruginosa, Acinetobacter baumannii, Aeromonas hydrophila

Metabolites: N-butyryl-L-homoserine lactone (CHEBI:29643 · MediaIngredientMech · CMMMech), N-(3-oxododecanoyl)-L-homoserine lactone (CHEBI:44534 · MediaIngredientMech · CMMMech)

Biological Processes:

Downstream Effects:
→ Disturbance-stable aerobic denitrification

PARTIAL - the authors attribute disturbance stability in part to interspecific communication and identify C4-HSL/3OC12-HSL in the corresponding treatments. The accessible abstract does not report signal-blocking or rescue experiments that isolate an AHL effect on denitrification.

Evidence

  • PMID:40020349 - SUPPORT (IN_VITRO)
    "interspecific communication was mainly carried out through N-butyryl-L-homoserine lactone (C4-HSL) and N-(3-oxododecanoyl)-L-homoserine lactone (3OC12-HSL)"

DBP-stimulated phenazine electron transfer

Under dibutyl phthalate disturbance, phenazine-1-carboxylic acid production accelerates electron transfer from the quinone pool to complex III in the aerobic-denitrification SMC.

Participating Taxa: Pseudomonas aeruginosa, Acinetobacter baumannii, Aeromonas hydrophila

Metabolites: phenazine-1-carboxylic acid (CHEBI:62412 · MediaIngredientMech · CMMMech)

Biological Processes:

Downstream Effects:
→ Disturbance-stable aerobic denitrification

PARTIAL - DBP-induced phenazine-1-carboxylic acid accelerates electron transfer, a route the authors associate with maintained SMC function under DBP. The abstract does not quantify its independent contribution to the approximately 93% denitrification endpoint or extend this phenazine mechanism to LOFX.

Evidence

  • PMID:40020349 - SUPPORT (IN_VITRO)
    "DBP stimulated phenazine-1-carboxylic acid production to accelerate electron transfer from the quinone pool to complex III"

Disturbance-stable aerobic denitrification

Division of labor and redistributed metabolic activity allow the three-member SMC to maintain approximately 93% aerobic denitrification efficiency under dibutyl phthalate and levofloxacin disturbances.

Participating Taxa: Pseudomonas aeruginosa, Acinetobacter baumannii, Aeromonas hydrophila

Biological Processes:

Evidence

  • PMID:40020349 - SUPPORT (IN_VITRO)
    "aerobic denitrification efficiency could be maintained at about 93 %"

Knowledge gaps & discussions (1)

KNOWLEDGE_GAP OPEN Do AHL or phenazine perturbations independently change denitrification stability under DBP and LOFX?

PMID:40020349 reports AHL communication, DBP-stimulated phenazine electron transfer and an approximately 93% denitrification endpoint. Only the abstract is cached; intervention and rescue details needed to isolate mediator-specific effects are unavailable. The two retained edges are marked PARTIAL, and the phenazine claim is restricted to DBP.
