Notes

Growth of two estuarine ciliates, Uronema nigricans and Potomacus potti, was inhibited when the bacterial food source was at a population level of < /=10E6-10E7 cells/ml. Feeding rates of Uronema varied with the type and population density of bacteria. The feeding rate of Uronema was greater when a Vibrio sp. served as food source compared with a Bacillus sp. Significant differences noted in the ciliate population levels were related to the strains used as food source.
