Some Issues of Ecophysiology of Free-living Ciliates

A. A. Koval'chuk
Uzhgorod National University Uzhgorod, Ukraine

ABSTRACT

Production experiments in situ and in vitro, as well as experiments on feeding and data on oxygen consumption by the free-living ciliates made it possible to study their energy budget depending on the temperature of a medium. On this basis the following coefficients were calculated: assimilation coefficient (U = 0.58), efficiency of using the consumed food for growth (K1 = 0.26), and efficiency of using the assimilated food for growth (K2 = 0.43). The temperature corrections are given to determine the natural level of ciliate metabolism under different temperature conditions.
