The fermentation broth of production for poly ((-glutamic acid) ((-PGA) was highly viscous because (-PGA was secreted to culture broth. The high viscosity of fermentation broth made separation process of (-PGA) to be difficult. And that most of cells producing (-PGA) had capsule composed of mainly (-PGA) so they had negative surface charges near neutral pH. The cell with negative surface charge had high stability in culture broth. The energy requirement for the separation of (-PGA) from fermentation broth was very high due to high viscosity of broth and high stability of cell. So we tried to find simple and economical process for the separation process of (-PGA). The cells were efficiently settled down by an acidification of fermentation broth that could induce the reduction of broth viscosity and surface charge |
