Abstract:
The effect of Nannochloris sp. on the toxicity of cultures of four algae was evaluated using a Microtox 500 that measures the effect on a light-producing bacterium, Vibrio fischeri. Cultures of four algae produced a toxic effect, but in the presence of Nannochloris sp., the effect was reversed, and a stimulatory effect was observed. The effect was tested for Microcystis aeroginosa, Cyclotella menengheniana, Scenedesmus dimorphis, and Lyngbya sp. using cultures obtained from the University of Texas Culture Collection of Algae.
