Pseudomonas fluorescens

Pseudomonas fluorescens is a type of bacteria commonly found in soil, water, and plant surfaces. It is known for its ability to produce a natural, glowing pigment called pyoverdine, which makes colonies appear fluorescent under certain lights. This bacteria plays a beneficial role in agriculture by promoting plant growth and controlling harmful pathogens. It is generally considered safe and environmentally friendly, often used as a biological control agent. While it can sometimes cause infections in immunocompromised individuals, it mainly exists as a helpful, natural part of the ecosystem.
