Аннотация: This study addresses competition between the Paramecium bursaria and zoochlorella - endosymbiosis and the infusoria Paramecium caudatum in a closed aquatic system. The system is a natural model of a simple biotic cycle. P. bursaria consumes glucose and oxygen released by its zoochlorella and releases nitrogenous compounds and carbon dioxide necessary for algal photosynthesis. P. caudatum was fed on bacteria. It was shown that the infusoria P. bursaria united in one cycle with Chlorella had a higher competitive ability than P. caudatum. With any initial percentage of the infusoria in the mixed culture, the end portion of P. bursaria reached 90 - 99%, which was significantly higher than the end portion of the P. caudatum population. It is assumed that the sustenance expenditures of P. caudatum were greater than those of the endosymbiotic paramecium, i.e. the closing of the components into a biotic cycle leads to a decrease in sustenance expenditures.

Заглавие : Effects of the bacterial component on the viability of the Paramecium bursaria symbiotic complex (infusorian-zoochlorella)
Колич.характеристики :5 с
Место публикации : Russ. J. Ecol.: MAIK NAUKA/INTERPERIODICA, 2001. - Vol. 32, Is. 4. - P261-265. - ISSN 1067-4136, DOI 10.1023/A:1011314622045

Ключевые слова (''Своб.индексиров.''): paramecium bursaria--endosymbiosis--matter exchange cycle
Аннотация: A hypothesis is considered that the establishment and maintenance of mass exchange processes in the Paramecium bursaria symbiotic complex (infusorian-alga) depends on the presence of the third component-bacteria-whose role is underestimated but essential for completing the exchange cycle. The role of this component in the symbiotic cycle of Paramecium bursaria is possible to reveal using special bactericidal preparations specifically inhibiting the bacteria involved in the metabolic cycle but having no effect on the functions of the host cell and the zoochlorella population. Experiments with various preparations of this type were performed, and the response to treatment was estimated from growth rates of the symbiotic complex and its components. This allowed identification of an antibiotic (rifampicin) that had no adverse influence on free-living zoochlorella and chlorella-free paramecia (the basic components of the symbiotic cycle) but drastically inhibited the growth of the P. bursaria symbiotic complex, which could be interpreted as evidence in favor of the hypothesis concerning the existence of the third symbiotic component.
