The algicidal bacterium Pseudomonas aeruginosa ACB3 effectively inhibited the growth and maximum quantum efficiency (Fv/ Fm) of unicellular Microcystis strains, but hardly inhibited the growth and Fv/ Fm of colonial Microcystis strains. Interestingly, bacterium ACB3 decreased the colony size of Microcystis. Considering that Microcystis occurs mainly as colonial aggregates in nature, our results will help understand the role of algicidal bacteria in affecting the growth of Microcystis. © The Author 2013.
