In silico engineering of Pseudomonas metabolism reveals new biomarkers for increased biosurfactant production [PDF]

PeerJ, 2018
Background Rhamnolipids, biosurfactants with a wide range of biomedical applications, are amphiphilic molecules produced on the surfaces of or excreted extracellularly by bacteria including Pseudomonas aeruginosa.

Bacterial rhamnolipids and their 3-hydroxyalkanoate precursors activate Arabidopsis innate immunity through two independent mechanisms

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance Activation of plant innate immunity relies on the perception of microorganisms through elicitors. Rhamnolipids and their precursor HAAs are exoproducts produced by bacteria.

Biosurfactants in Plant Protection Against Diseases: Rhamnolipids and Lipopeptides Case Study

Frontiers in Bioengineering and Biotechnology, 2020
Biosurfactants are amphiphilic surface-active molecules that are produced by a variety of microorganisms including fungi and bacteria. Pseudomonas, Burkholderia, and Bacillus species are known to secrete rhamnolipids and lipopeptides that are used in a ...

Rhamnolipids produced by Pseudomonas: from molecular genetics to the market

Microbial Biotechnology, 2020
Rhamnolipids are biosurfactants with a wide range of industrial applications that entered into the market a decade ago. They are naturally produced by Pseudomonas aeruginosa and some Burkholderia species. Occasionally, some strains of different bacterial

Rhamnolipids from non-pathogenic Acinetobacter calcoaceticus: Bioreactor-scale production, characterization and wound healing potency.

New Biotechnology, 2021
Rhamnolipids are predominantly produced from the opportunistic pathogen Pseudomonas aeruginosa, which restricts their scaled-up production and biomedical applications. Moreover, the wound healing property of rhamnolipids is mainly focused on either mono-

Rhamnolipid Micellization and Adsorption Properties

International Journal of Molecular Sciences, 2022
Biosurfactants are naturally occurring amphiphiles that are being actively pursued as alternatives to synthetic surfactants in cleaning, personal care, and cosmetic products. On the basis of their ability to mobilize and disperse hydrocarbons, biosurfactants are also involved in the bioremediation of oil spills.
