MICROBIALLY PRODUCED RHAMNOLIPIDS (BIOSURFACTANTS) FOR THE CONTROL OF PLANT PATHOGENIC ZOOSPORIC FUNGI

Disclosed is the use of biosurfactants as biological control products. In particular, rhamnolipid biosurfactants produced by Pseudomonas spp. were demonstrated to rapidly kill zoospores by rupturing the plasma membrane of three representative zoosporic plant pathogenic microorganisms: Pythium aphani...

Beschreibung
Zusammenfassung:	Disclosed is the use of biosurfactants as biological control products. In particular, rhamnolipid biosurfactants produced by Pseudomonas spp. were demonstrated to rapidly kill zoospores by rupturing the plasma membrane of three representative zoosporic plant pathogenic microorganisms: Pythium aphanidermatum, Plasmopara lactucae-radicis, and Phytophthora capsici. L'invention porte sur l'emploi de tensioactifs biologiques comme produits de lutte biologique. Il s'agit notamment de tensioactifs biologiques rhamnolipides produits par l'espèce Pseudomonas dont il a été démontré qu'ils tuaient rapidement des zoospores par rupture de la membrane plasmique de trois micro-organismes représentatifs zoospores pathogènes des plantes, à savoir: Pythium aphanidermatum, Plasmopara lactucae-radicis et Phytophthora capsici.
