| description | Blooms of harmful cyanobacteria <i>Microcystis aeruginosa</i> lead to an adverse effect on freshwater ecosystems, and thus extensive studies on the control of this cyanobacteria’s blooms have been conducted. Throughout this study, we have found that the two bacteria <i>Aeromonas bestiarum</i> HYD0802-MK36 and <i>Pseudomonas syringae</i> KACC10292<sup>T</sup> are capable of killing <i>M. aeruginosa</i>. Interestingly, these two bacteria showed different algicidal modes. Based on an algicidal range test using 15 algal species (target and non-target species), HYD0802-MK36 specifically attacked only target cyanobacteria <i>M. aeruginosa</i>, whereas the algicidal activity of KACC10292<sup>T</sup> appeared in a relatively broad algicidal range. HYD0802-MK36, as a direct attacker, killed <i>M. aeruginosa</i> cells when direct cell (bacterium)-to-cell (cyanobacteria) contact happens. KACC10292<sup>T</sup>, as an indirect attacker, released algicidal substance which is located in cytoplasm. Interestingly, algicidal activity of KACC10292<sup>T</sup> was enhanced according to co-cultivation with the host cyanobacteria, suggesting that quantity of algicidal substance released from this bacterium might be increased via interaction with the host cyanobacteria. |
