Industrial glycerol obtained through the transesterification process using rapeseed oil did not support growth of several strains ofClostridium butyricum obtained from bacterial culture collections. Ten new strains ofC. butyricum were obtained from mud samples from a river, a stagnant pond, and a dry canal. These new isolates fermented the commercial glycerol and produced 1,3-propanediol as a major fermentation product with concomitant production of acetic and butyric acids. Four of the ten… CONTINUE READING
