| 초록 |
The stagnant region of fermentation broth could be observed easily during poly (g-glutamic acid) (g-PGA) fermentation due to its high viscosity. The cells in stagnant region would be experienced the shortage of nutrients such as oxygen and carbon sources. Thus this could induce cell damage and reduce productivity of g-PGA. It is possible to reduce the stagnant region and local shortage of nutrients by fitting or retrofitting of fermentor if we could predict the stagnant region. In this study the mathematical model was used to predict the stagnant region in 5 L , 30 L of fermentor with high viscosity of broth. |
