    Product Description

    Pyoluteorin is a bichlorinated pyrrole produced by several species of Pseudomonas that demonstrates antibiotic, antifungal, and herbicidal activity. Pyoluteorin production is influenced by positive autoregulation and has been shown to function as a signal molecule negatively regulating additional secondary metabolites produced by Pseudomonas.1

    WARNING This product is not for human or veterinary use.
