Surfactin and fengycin lipopeptides of Bacillus subtilis as elicitors of induced systemic resistance in plants.
Experiments conducted on bean and tomato plants showed that overexpression of both surfactin and fengycin biosynthetic genes in the naturally poor producer Bacillus subtilis strain 168 was associated with a significant increase in the potential of the derivatives to induce resistance.
PAMPs, MAMPs, DAMPs and others: an update on the diversity of plant immunity elicitors
La comprehension des bases physiologiques et biologiques des mecanismes de ces immunites a beaucoup progresse ces dernieres annees, mais une connaissance plus approfondie des me canismes sous-jacents a the perception of ces eliciteurs est cependant essentielle pour developper de nouveaux moyens de controle des nuisibles.

Evidence is provided for the role of secreted lipopeptides, and more particularly of fengycins, in the protective effect afforded by the strain against damping-off of bean seedlings caused by Pythium ultimum and against gray mold of apple in post-harvest disease.
Influence of culture conditions on lipopeptide production by Bacillus subtilis
This study studied the effects of different media on the nature of the synthesis of fatty acid chains for each lipopeptide family and found that the intensity of production of homologous compounds depends on the strain and the culture medium.
