The showdown competition is run by synthetic bacteria. Predators and prey communicate and regulate each other's density. Via molecular signals, the predator cells kill the prey while living prey rescues predators. The diverse and colorful crowd surrounding the spectacle was genetically engineered to carry different pigments which has been appreciated at the iGEM competition 2009. | The showdown competition is run by synthetic bacteria.
