4.12 Production of
1,3-propanediol
A process for microbial synthesis
of 1,3-propanediol is being developed for the manufacture of
'green' polyester fabric from renewable resources. Under anaerobic
conditions, a selected strain of Klebsiella pneumoniae converts
glycerol ((231-1803) to 1,3-propanedi01 (C3H802) and acetic acid
(C2H402), with minimal formation of other fermentation products
such as butyric acid, ethanol, and 1-12 gas. The fermentation and
cell growth equation can be written as:
68 C3H803 + 3 NH3 = 3 C4H702N + 49 C3H802...
