Continuous fluidized bed bioreactor packed with activated carbon and cellulose as a carrier was used to evaluate the removal efficiency of blue-green alga, Phormidium tenue and its metabolite, 2-methylisoborneol (2-MIB).The removals of P. tenue and total 2-MIB (including intracellular and dissolved 2-MIB) by fluidized bed biological activated carbon (FBA) were 89.1% and 68% at 20°C for 7 days, while those of them by fluidized bed biological cellulose (FBC) were 85.3% and 57% under the same condition. FBA showed relatively higher removal than FBC.Protozoan, Monas sp. on biofilm was closely correlated with the ingestion of viable cells of P. tenue, and its dissolved 2-MIB was found to be efficiently assimilated by the aggregated bacteria on the biofilm. It was indicated that the removal difference of 2-MIB by continuous fluidized bed bioreactor was dependent on the kind of carriers.
