To clarify the effect of SOT medium concentration on the specific growth rate of the blue–green alga S. platensis, the alga was cultured in media containing SOT components at concentrations of 0.050–5.0 times. The specific growth rate of S. platensis decreased in cultures at 4.0 times or higher concentrations of SOT components. It also decreased when the medium was diluted to 0.40 times or lower concentrations of SOT components.
