| The effects of CellCaSi and bioflocculant on the control of algal bloom were investigated in enclosures in a small eutrophic pond. The bioflocculant produced by a bacterial strain S-2 was finally selected to remove Microcystis aeruginosa which was a dominant species of algal bloom in the pond. Enclosure experiment showed that phosphorus concentration decreased dramatically from $131mu{g}ell^{-1}$ (Control) to $1-14mu{g}ell^{-1}$ in three CellCaSi-enriched enclosures. Chlorophyll $-alpha$ concentration also decreased from $215mu{g}ell^{-1}$ (Control) to $59mu{g}ell^{-1}$ by the addition of CellCaSi $(1gell^{-1}$, bioflocculant $(2mlell^{-1}$, calcium chloride $(1gell^{-1}$ and ferric chloride $(2mg;Feell^{-1})$ in Enclosure 4. From the results of the mouse acute toxicity test of the S-2 bioflocculant and the goldfish survival test in enclosures, it seems that both the S-2 bioflocculant and the CellCaSi do not show any severe toxicity in water system. Consequently, it was concluded that the bioflocculant and the CellCaSi could be used to control algal bloom in eutrophic waters by removing phosphorus and chlorophyll$-alpha$ |
