Flavin-containing a-glycerophosphate dehydrogenases have been found also in Streptococcus faecalis ( 44) and Propionibacterium arabinosum (24B). The enzyme from 5. faecalis is reported to contain FAD, have a Km for < -glycerophosphate of 4 mM, and a pH optimum of 5.8. In addition to dyes, this enzyme can interact directly with molecular oxygen to form H2O2. The preparation from P. arabinosum is particle-bound, has a Km for a-glycerophosphate of 26 /lAf, and is claimed to contain flavin and nonheme iron.

In the fermentation of glucose by Propionibacterium arabinosum, the C of both 1-, and 3,4-labeled glucose was found in every carbon of the products—propionic acid, succinic acid, and CO2. The results are consistent with the explanation that glucose is split to two three-carbon compounds and to CO2 plus a five-carbon compound, and that randomization occurs by means of symmetric three- and four-carbon compounds. 

All propionic acid bacteria are catalase-positive P. arabinosum displays a very weak catalase activity). As a rule, members of the genus Propionibacterium produce significant amoxmts of vitamin Bn. We (Vorobjeva, 1976) suggested to differentiate propionibacteria by the nature of the coenzyme form of vitamin Bn. The presence of the isomerization reaction of succinyl-CoA methylmalonyl-CoA, which is the key reaction of propionic acid fermentation, represents another valuable taxonomic property of the genus.
