Bacterial inner membranes are enriched in cardiolipin (10–25% of phospholipid) relative to mammalian mitochondrial inner membranes at physiological concentrations; this compositional difference enables selective protonophoric uncouplers that dissipate bacterial membrane potential at cardiolipin-enriched membranes but are inactive at mammalian mitochondrial membranes. Because membrane potential is thermodynamically essential for bacterial viability and resistance mutations reducing cardiolipin content impose severe fitness costs in biofilm environments, cardiolipin-selective protonophores represent the only antimicrobial class for which sustainable resistance is mathematically excluded by the fitness landscape, making them uniquely resistance-proof.

Grok: The hypothesis is falsifiable through experiments comparing cardiolipin content and protonophore effects across bacterial and mammalian membranes, and it aligns with known compositional differences; however, the claim of being uniquely resistance-proof is speculative and lacks direct evidence fro...

ChatGPT: The hypothesis is logically constructed and falsifiable, but it overstates the sustainability of resistance-proofing; the referenced literature supports the essentiality of membrane potential and fitness costs but also highlights compensatory mechanisms and evolutionary adaptability that could en...

Mistral: The hypothesis is falsifiable, well-supported by the cited papers on membrane composition and fitness costs, and presents a compelling mechanistic argument. However, the claim of *mathematically excluded* resistance is overly absolute, as compensatory mutations or alternative resistance pathways ...

Claude: ** The hypothesis stacks multiple unverified premises (bacterial CL content of 10–25% is overstated and highly species/condition-dependent; mammalian mitochondrial inner membranes actually contain ~20% CL, undermining the claimed selectivity gap), none of the cited papers address cardiolipin-sel...
