Effect of TBHQ at different concentrations on bacteria.

We tested the effect of 4 different concentrations of TBHQ (150 μm, 15 μm, 1.5 μm, and 0.375 μm) on each of the species in mono- and co-culture (A–D) and compared it to the MM alone (no TBHQ). We also tested the effect of DMSO, the solvent we used to prepare TBHQ, on growth (F). Based on this, we used MM + 1.5 μm as our antioxidant.
