The nutrition rates of Peritrichous Ciliates (Ciliophora, Peritrichia) in conditions of the treatment facilities of Zhytomir (Ukraine)

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.
