| Research Abstract |
Bioaugmentation is a method to use a special microorganism for soil cleanup. However, microorganisms introduced to a contaminated site decrease rapidly in many cases. In this research, we found out that the decrease was caused by protozoa existing in the natural environment. Most of protozoa that we have found were flagellates that were classified to Chrysophyceae, Stramenopiles. Several flagellates were isolated and they were found to ingest various kinds of bacteria.
