Acylated homoserine lactones (AHLs) play a widespread role in intercellular
communication among bacteria. The Australian macroalga Delisea pulchra
produces secondary metabolites which have structural similarities to AHL
molecules. We report here that these metabolites inhibited AHL-controlled
processes in prokaryotes. Our results suggest that the interaction between
higher organisms and their surface- associated bacteria may be mediated by
interference with bacterial regulatory systems.
