2,4-diacetylphloroglucinol

Patent Granted 2,4-Diacetylphloroglucinol is a natural phenol found in specific strains of the Gram-negative bacterium Pseudomonas fluorescens.[1] This compound is found to be responsible for the antiphytopathogenic[2] and biocontrol[3] properties in these strains. It is also found in Pseudomonas protegens where it has the same activity against various plant pathogens.[4][5] 2,4-Diacetylphloroglucinol is also produced by Lysobacter gummosus, a bacterium which lives on the skin of redback salamanders.
