Abstract

A Protozoa, Tetrahymena sp. was isolated from domestic wastewater and identified by morphological characteristics. It was 50 to $70{\mu}m$ in length, ovoidal shape, and divided by binary fission. When Escherchia coli was fed as a food microorganism, the optimal conditions for growth were 30 to $35^{\circ}C$, pH 7 to 9 and 0.05% NaCl. The growth was inhibited by heavy metal ions; 0.3 mg of $Cd^{++}/l$ and 0.1mg of $Cu^{++}/l$. While, it was not inhibited up to 0.7 mg of $Zn^{++}/l$.
