Aging impact on nisin-treated biofilm biomass spectra. The spectra that remains after application of a large diffusion encoding gradient pair (3.7 T m⁻¹, 2.44 ms, q = 2.85 × 10⁵ m⁻¹). A high degree of similarity exists between the spectra even after contact with the nisin for two days without additional nutrients in the refrigerator. The spectra have been scaled so that the areas under the spectra are equivalent, as after 13 days of aging, the absolute area under the spectra at this high q value has decreased by 77%.
