| Abstract: | The fermentation conditions of 1,3-propanediol high-producing strain CpN-38 were studied. The optimum conditions of producing 1,3-PD were: initial pH 7.0,temperature 30℃, culture time 40 h, inoculum size 8%.Under the optimum conditions, the productivity of 1,3-PD reached up to 29.38 ?g/(L·d) and the 1,3-PD yield reached up to 49.07 ?g/L in 30?L fermentor by CpN-38. |
| Keywords: | Clostridium pasteurianum 1 3-PD fermentation conditions |
