Abstract

genus. Production of variovoracin analogues was demonstrated in two strains predicted to produce mono-rhamnosylated congeners, further validating the assignment of the variovoracin BGC. Despite their structural similarity to the rhamnolipids, the characteristic curvature (Cc) of the variovoracins has the opposite sign, indicating that their non-ionic and hydrophobic properties confer unique functional characteristics and consequently different surfactant applications.
