^aHeadspace monitoring results are presented in the Supporting Information.
^bCalculated according to equation S-1 in Additional file 1.
^cIncludes three bottles that also received 500 mg/L CF, which had no effect of the F^- mass balance, CS = corn syrup.
^d ± = Standard deviation.
^eInoculum was washed in fresh MSM to avoid carryover of B₁₂.
