There are three main components to the bacterial music generator: (1) bacteria colonies (2) tube rack (3) button control. We engineered bacteria to express different colors and lights through chromoproteins, fluorescent proteins, luciferase, and oscillating amounts of luciferase. We then translated bacterial colonies on a plate into a step sequencer, which creates patterned expressions of sound. The tube rack and button control add extra layers of interaction and control, making the user the coolest DJ ever.
