Popis: Batch growth and chemostat culture experiments were carried out with the marine alga Tetraselmis suecica (Kylin), a unicellular alga which is potentially useful for wastewater treatment by controlled eutrophication. In natural (Mediterranean coastal) seawater enriched with nutrients, at 22°C, under illumination at 12 h 12 h light/dark, with an intensity of 500 ft-candles, the maximal specific growth rate was μmax = 0.61 day−1 (base e), measured both in batch and in chemostat experiments. Cell population densities were determined as a function of temperature at fixed dilution rates. The optimal growth temperature was between 25 and 27°C. With an abundant supply of nutrients, it was possible to sustain substantial population densities in the temperature range of 15–32°C.
