A species-defined microcosm, consisting of bacteria Escherichia coli DH5a, protozoa Tetrahymena thermophila B and algae Euglena gracilis Z, was synthesized in which all species co-existed for over 130 days. This microcosm was developed as an experimental system to study gene-population interaction in a community.
