Abstract
Glycerol was fermented with the production of 1,3-propanediol as the major fermentation product by four strains of
Clostridium acetobutylicum
, six of
C. butylicum
, two of
C. beijerinckii
, one of
C. kainantoi
, and three of
C. butyricum
. 1,3-Propanediol was identified by its retention times in gas chromatography and high-pressure liquid chromatography and by its mass spectrum. During growth of
C. butylicum
B593 in a chemostat culture at pH 6.5, 61% of the glycerol fermented was converted to 1,3-propanediol. When the pH was decreased to 4.9, growth and 1,3-propanediol production were substantially reduced.
