| Abstract: | B. ammoniagenes MA 2 and B. flavum MA 3 were collected by using chitosan as flocculant. The optimum conditions such as the amount of chitosan used, the velocity of agitator and mixing time which influence the enzyme activity and separation effects were determined. The flocculating process of collecting B.ammoniagenes MA 2 and B.flavum MA 3 with chitosan was also analyzed. |
