title: Diffusion susceptibility demonstrates relative inhibition potential of sorbent-immobilized heavy metals against sulfur oxidizing acidophiles.
abstract: A new generation of laminates and cementitious materials incorporate antimicrobial metals into domestic infrastructure. Conventional culturing approaches are unsuitable for assessing the inhibitory properties of these materials. Modifications to the radial Kirby-Bauer antibiotic assay, which incorporate metal impregnated activated carbon in linear formats, reveal relative metal sensitivities of destructive acidophiles.
