Pseudomonas chlororaphis (PcO6), a rhizosphere bacterium, is important to agriculture because of its use as a biological control against fungus and other pests. This biological control correlates with production of phenazines; a process regulated by acyl homoserine lactones (AHSLs). Long chain AHSLs might also have an affect on the production of phenazines. My research showed that PcO6 produced long chain AHSLs and that production is affected by nutrition with more long chain AHSLs produced in rich medium than minimal medium. The nutritional studies and findings with different mutants of PcO6 altered in phenazine production suggest that control of these antifungal compounds is not the major role of these long chain fatty acid signaling molecules. Long chain AHSLs production is also influenced by Pluronics in the media. 2
