Abstract: | The effect of various bacteria on the growth of and hemolysin production by Amphidinium carterae was studied. The algal culture had an indigenous bacterial flora of Moraxella and Pseudomonas and these could not be eliminated by treatment with bactericidal antibiotics like gentamicin. Various bacteria like Micrococcus, Aeromonas, Vibrio, and Moraxella-like bacteria were added to A. carterae cultures to study their effect on growth and hemolysin production. Micrococcus and Aeromonas were found to improve the growth marginally. Hemolysin titres were considerably higher in A. carterae cultures supplemented with bacteria.
