Three Population Cascade Overview
An oscillator is a system that repeatedly goes back and forth about a specific level of expression in order to achieve an equilibrium. Many think of an oscillator as being a physical system such as a pendulum or a clock, but oscillators are also repeatedly found in biological systems. Biological oscillators are characterized by a positive and negative feedback loop.
For our oscillator, we created three different strains using E.coli bacteria. These strains used three different quorum sensing molecules acyl homoserine-lactone (AHL), (autoinducer-1) AI-1, and (autoinducer-2) AI-2 coupled with yellow, red, and cyan fluorescent proteins to create a visual oscillating effect.
