Pseudomonas brassicacearum strain DF41 kills Caenorhabditis elegans through biofilm-dependent and biofilm-independent mechanisms.

ABSTRACT: Pseudomonas brassicacearum DF41 is a biocontrol agent that suppresses disease caused by the fungal pathogen Sclerotinia sclerotiorum A number of exometabolites are produced by DF41 including the lipopeptide sclerosin, hydrogen cyanide (HCN) and degradative enzymes. Production of these compounds is controlled at both the transcriptional and posttranscriptional level by quorum sensing (QS) and the Gac-two component regulatory system. In order to be successful, a biocontrol agent must persist in the environment at levels sufficient for pathogen control. Bacterivorous predators, including nematodes, represent a challenge to the establishment of introduced microorganisms. In the current study, DF41 was investigated for its ability to resist predation by Caenorhabditis elegans. We discovered tha
