| Abstract |
Is it possible to define exactly toxicity of pollutants upon a Desulfovibrio-culture by means of the continuous culture? Disturbing increase of pesticids and other pollutants which attain the Waddensea via the river Rhine stirred us to make several researches. Desulfovibrio, a very general representant of the Waddensea, was made an example for these researches because of her interesting metabolitical qualities, likewise its short generation time. In spite of the imperfect methode of these experiments, we can by means of the continuous culture explain more about the influence of a pollutant upon the growth of an organism than it would have been possible in case of a batch-culture. During the experiment a division has been made between a) the influence upon exponential growth-rate, b) the influence upon metabolism. In the first case culture will wash out, in the other case there will be question of a smaller growth result. At the same time experiments have been done with pollutants in a batch-culture, as well with gathered cells. |
