Dovgal %J Natura Montenegrina, Podgorica %T The nutrition rates of Peritrichous Ciliates (Ciliophora, Peritrichia) in conditions of the treatment facilities of Zhytomir (Ukraine) %X The article deals with testing of the method of peritrichous ciliates nutrition rate evaluation using the square number of food vacuoles (SNFV) index. The indexes were judged for most common in treatment facilities for peritrichous species: Vorticella striata f. octava, Epistylis plicatilis, E. bimarginata, Opercularia phryganeae and V. convallaria. The dependence of the nutrition rates of peritrichous ciliates on the temperature, operating conditions of treatment facilities and season were estimated. The method is recommended for control of sewage disposal plants operating efficiency as well as in bioassay. %N 2 %K food vacuoles, nutrition rate, peritrichs, treatment facilities %P 51-61 %V 8 %D 2009 %L zu222628
