Abstract : Environmental requirements are reported for maximum growth of ten strains of marine flagellates of the group Volvocales. Three strains display growth rates above average for green algae: Dunaliella tertiolecta, D. primolecta, and Tetraselmis tetrathele. The algae examined display a spectrum of salinity optima, allowing selection of a strain suitable for mass culture in water of most any available salt content. The temperature optimum for growth is found to vary with the salt concentration of the growth medium for D. tertiolecta. All strains so far examined are unusually tolerant of urea, although not all can use urea as a source of nitrogen for growth. First attempts to obtain mutants capable of utilizing bright light were unsuccessful but provided data on pigment composition and photosynthetic rates of algal cells adapted to growth in light about 1.5 times as intense as sunlight.
