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