Lactic Acid → 11006-76-1

Participants

Reaction Steps

To determine the Lactrol® dose required to prevent lactic acid formation during hydrolysate fermentation, a portion of intentionally-contaminated seed culture F1067 at EFT=19.3 hr (from Example 1) was used as a seed culture to inoculate cob hydrolysate medium (FRF13; see General Methods) (adjusted to pH 5.8, +10 mM sorbitol) at 10 vol % (final volume) containing either 0 ppm (sample F1069) or 2 ppm (sample F1071) of Lactrol®, which was then fermented at 33° C. (reduced to 30° C. at EFT=21 hr) and pH 5.8 (adjusted with 4 N NaOH).
