Abstract:
:Six microorganisms that produced acetoin or diacetyl or both from glucose were tested for the production of 2,3-butylene glycol from lactose. Bacillus polymyxa and Streptococcus faecalis gave positive results and were tested in unmodified wheys. Cottage cheese whey was unsatisfactory, but B. polymyxa produced large amounts of the glycol in sweet whey, about 60 mmol of glycol per 100 mmol of lactose utilized. Aeration and an increased ratio of surface area to volume of whey enhanced the production of glycol. 2,3-Butylene was separated from the spent whey and from acetoin and diacetyl with a Sephadex G-10 column.
