Abstract
Cultures of P. tricornutum were grown under different light intensities and nutrient supplies, and the effects of naphthalene on the photosynthesis of these cultures were examined. The cultures were grown in a turbidostat and a chemostat. The cells adapted to low light intensities by improving the utilization of the lower irradiances. N limitation reduced the light saturated photosynthesis. Each concentration of naphthalene depressed the maximal photosynthesis of P. tricornutum grown under different conditions to nearly the same extent. The growth conditions thus had no influence on the sensitivity of P. tricornutum to naphthalene.
