To examine the algicidal effect of co-treatment of biological control agent on centric diatom Stephanodiscus hantzschii in the filtered water, an endemic algicidal bacterium (Pseudomonas putida) and a heterotrich ciliate (Stentor roselli) were iso-lated from Pal'tang reservoir, Korea. Bacterial isolate and ciliate removed 98% and 80% of the diatom for 7 days of cultivation. Co-treatments of these two agents perfectly inhibited the diatom growth, compared to the single treatment of each agent. This synergistic interaction of the bacterium and ciliate could provide an effective tool in the biomanipulation to control the diatom bloom in freshwater lakes and streams.
