• 1) To reveal the food habit of three species of Vorticellidae which were deemed most significant in purifying polluted waters by activated sludge, pure cultures of several strains of bacteria which were expected to be in the sludge were prepared to secure the protozoan food. 2) Some of the bacteria could be metabolized by Vorticellidae, whereas the remaining species could not be taken up by the protozoa. 3) If a mixed diet of the bacteria favorable for the protozoan growth was served, the specific growth rate of Vorticellidae approached that value which was experienced when the heterogeneous bacteria isolated from the sludge were given in situ. 4) Judging from another observation that Vorticella microstoma did not proliferate in the sludge extract medium when the favorable bacteria as food were inactivated by antibiotics and in addition, that no growth of the protozoa was noted when sterile rice-bran, boiled egg yolk or sterilized SS (suspended solid) from a raw sewage was given as food, Vorticellidae was presumed to take only the bacteria. So far, Vorticellidae was found stenophagic and holozoic. 5) A relationship demonstrated between the microflora and -fauna in the sludge presents a clue leading to the biochemical and microbiological control of the biotic community in the activated sludge process.
