The effect of adding two different organic materials; wheat extract and bactopeptone was studied on some of the most abundant bacterivorous hymnostomes collected from freshwater canal in Shibin El-Koum, Menoufia, Egypt. It was found that some of these ciliates prefer plant protein such as wheat, others prefer animal protein such as bactopeptone, and some have the ability to accomodate with both organic materials. A significant positive relationship between log doubling times and log cell volumes of these hymnostomes was confirmed.
