Table 3. Different parameters for 1,3-propanediol production by various strains.
| Method | Description | Parameter value | Strain | Reference |
|---|---|---|---|---|
| Batch fermentation | Easy operation, short cycle, low contamination rate, low titre or yield, complicated kinetic parameter measurements | γ(titre)=78.5 g/L | C. diolis GSHM 2 | (72) |
| Υ=0.65 mol/mol | C. butyricum YJH-09 | (73) | ||
| r=0.78 g/(L·h) | L. brevis N1E9.3.3 | (74) | ||
| Fed-batch fermentation | Constant substrate concentration or feed rate, kinetic paremeter analysis, high productivity, possibility of contamination, species degeneration | γ(titre)=87.5 g/L | K. pneumoniae 2-1 | (36) |
| Υ=0.67 mol/mol | K. pneumoniae DSM 4799 | (75) | ||
| r=3.29 g/(L·h) | K. pneumoniae KG1 | (70) |
Υ=yield, r=productivity
