ANOTHER RARE STAMP. “Even farther down the organismal path is the two-species bacterial consortium “Chlorochromatium aggregatum,” which has been championed as a model of bacterial multilineage multicellularity. In this symbiosis, green sulfur bacterial epibionts (Chlorobium chlorochromatii) surround a motile β-proteobacterium (Symbiobacter mobilis). The central bacterium relies extensively on the photosynthetic products of its epibionts and has undergone extensive genome reduction, a mark of evolved dependence.”
