To assess the algicidal effect of a bacterium, Pseudomonas fluorescens HYK0210-SK09 (SK09), attached to activated carbon polyvinyl alcohol (ACPA) and cellulose sponge (CS) carriers against Stephanodiscus hantzschii, the present study was carried out in an indoor-microcosm. As comparing immobilization effects of two carriers, the ACPA carrier allowed for higher packing cell density of SK09 compared to the CS carrier. In the microcosm, immobilized SK09 cells were applied to control S. hantzschii blooms. Immobilized SK09 cells exhibited a species-specific activity towards the diatom, showing an algicidal effect up to 72% attached by ACPA carriers and to 51% attached by CS carriers. In particular, a level of conductivity treated with ACPA carriers was decreased than that of CS carriers. The present study clearly demonstrates that ACPA-immobilized SK09 cells could effectively control S. hantzschii blooms and improve water quality in the microcosm ecosystem.
