Process for conversion of glycerine into 1,3-propanediol by microorganisms using a strain of microorganisms selected from clostridium, Enterobacterium, Lactobacillus, Citrobacter, Aerobacter and Klebsiella which is capable of converting glycerine into 1,3-propanediol in a space time yield of more than 0.5 g per hr. per l in a 5 wt% glycerine soln. as sole carbon source under standard fermentation conditions, comprises using the chosen microorganism for conversion of a 5-20 wt%., (10-15 wt%) soln. of glycerine as sole carbon source under anaerobic conditions while maintaining a constant pH, and after extensive conversion of the glycerine, sepg. obtd. biomass and working up the prod. mixt. by distn. |
