Résumé

Known for more than 60 years and among the best studied biosurfactants, rhamnolipids comprise a diverse group of mono- and di-sugar amphiphilic glycolipids with surface-active properties. Produced by various bacteria, the best known being Pseudomonas aeruginosa and a few Burkholderia species, these fascinating molecules still hold many secrets and promises. Although we have learned a lot on the genetic and metabolic regulation of rhamnolipid production in P. aeruginosa, the pathogenic potential of this bacterial species represents an incentive to develop alternative production models. In this regard, the intrinsic capacity of a few Burkholderia species which are not human pathogens, such as B. thailandensis and B. glumae, to produce rhamnolipids, although different from the ones produced by P. aeruginosa, is especially promising, while posing a whole new set of challenges. In this presentation, I will argue that a better understanding of the reasons why bacteria produce rhamnolipids is key to develop procedures to optimize their productivity.
