Pyocyanin is a small, hydrophobic molecule that belongs to the phenazine family. It is responsible for the characteristic blue-green color of P. aeruginosa cultures. This compound is known for its ability to generate reactive oxygen species (ROS), which play a pivotal role in its toxic effects. Pyocyanin acts as a redox-active compound, cycling between oxidized and reduced states, which contributes to oxidative stress in host cells.
