aurantiaca is an orange Gram-negative soil bacterium, originally isolated from the rhizosphere soil of potatoes.

It produces di-2,4-diacetylfluoroglucylmethan, which is antibiotically active against Gram-positive organisms.

[2] It has shown potential for use as a biocontrol agent against plant-pathogenic microbes.

[3] Originally described as Pseudomonas aurantiaca based on 16S rRNA analysis it has been placed in the P. chlororaphis group.

[4] Isolates found in Ukraine living in root symbiosis produce 2,4-Diacetylphloroglucinol to control Fusarium oxysporum.
