Glycerol fermentation

Schauder R, B Schink (1989) Anaerovibrio glycerin sp. nov., an anaerobic bacterium fermenting glycerol to propionate, cell matter and hydrogen. Arch Microbiol 152 473-478. 

In aU bacteria able to ferment glycerol to 1,3-PD the genes encoding for the four enzymes specific for glycerol fermentation are expressed in common in the so-caUed dha regulon dha from dihydroxyacetone, the first intermediate in the... 

Anaerovibrio glycerini ferments glycerol to propionate (Schauder and Schink 1989) and D. carbinolicus to 3-hydroxypropionate (Nan-ninga and Gottschal 1987). 

One of the most subtle stereospeciflcity of enzymes relates to their ability to distinguish between two identical atoms/groups (proR versus proS) bonded to a carbon atom in prochiral stereospeciflcity (Hanson and Rose, 1975). For example, yeast fermentative glycerol kinase catalyzes phosphorylation of only one (proS) of the two chemically identical primary hydroxyl groups to yield L-glycerol-3-phosphate ... 

The discovery of the fiction of CO, by heterotrophes was first made in the propionic add bacteria (Wood and Werkmann). In these bacteria when fermenting glycerol the CO, is utilized for the formation of succinic add. Elsden has shown that for E. coU the rate of formation of succinate in the presence of pyruvate depends upon the CO, pressure. 

Regulation Between Alcoholic Fermentation and Glyceropyruvic Fermentation Glycerol Accumulation... 

Some of the microorganisms ferment glycerol to produce 1,3-propanediol (Bouvet et al., 1995). 

Industrial production of glycerol from fermentation has not yet become an actuality in the United States, but some of the processes described above have merit. With the coming of more normal economic conditions and when lower cost sugar becomes available in the form of molasses, or otherwise, fermentation glycerol might become a commercial possibility.
