BACTERIAL BUTYLENE GLYCOL DEHYDROGENASE AND DIACETYL REDUCTASE

Bacterial Butylene Glycol Dehydrogenase and Diacetyl Reductase* by Harold

The early literature indicates much confusion as to the origin of acetylmethylcarbinol and butylene glycol in microbiological fermentations. Happold and Spencer (1) have reviewed much of this early work and have studied in detail the conditions for the formation of acetylmethylcarbinol and butylene glycol from glucose and pyruvate by Aerobacter aerogenes. Juni (2) has demonstrated that acetoin ...

Origin and relationship of acetylmethylcarbinol to 2:3-butylene glycol in bacterial fermentations.

Purification and characterization of polyethylene glycol dehydrogenase involved in the bacterial metabolism of polyethylene glycol.

Polyethylene glycol (PEG) dehydrogenase in crude extracts of a PEG 20,000-utilizing mixed culture was purified 24 times by precipitation with ammonium sulfate, solubilization with laurylbetaine, and chromatography with diethylamino-ethyl-cellulose, hydroxylapatite, and Sephadex G-200. The purified enzyme was confirmed to be homogeneous by sodium dodecyl sulfate-polyacrylamide gel electrophoresi...

Synthesis of elastic biodegradable polyesters of ethylene glycol and butylene glycol from sebacic acid.

High molecular weight biodegradable polyesters were prepared from sebacic acid, ethylene glycol and butylene glycol through a simple non-solvent polycondensation with a low toxicity catalyst. The successful synthesis of the polyesters was confirmed by gel permeation chromatography, (1)H-nuclear magnetic resonance and Fourier transform-infrared spectroscopies and differential scanning calorimetr...

Microbial production of 2,3-butylene glycol from cheese whey.

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 lac...
