A process for the microbial synthesis of 1,3-propanediol ( 3 8 2 C H O ) uses an anaerobicfermenter with a selected strain of K. pneumoniae to convert glycerol ( 3 8 3 C H O ) to 1,3-propanediol and acetic acid ( 2 4 2 C H O ). All other byproducts are of negligible concentration.The fermentation and cell growth equation can be written:3 8 3 3 4 7 2 3 8 2 2 4 2 2 2 68 3 3 49 15 15 40 C H O NH C H O N C H O C H O CO H O + → + + + +The continuous fermentation process is set up at 37°C and atmospheric pressure.Anaerobic conditions are maintained by sparging the fermentation broth with N2 at aflowrate of 500 litres per minute. The medium, containing ammonia, is fed at 500 kg perhour, and has a composition of 14% (w/w) glycerol. Suppression of the side reactions isachieved by excess glycerol, so the liquid product contains 3% (w/w) unreacted glycerol.2a. Draw a process diagram.
