Monorhamnolipid is a type of biosurfactant produced by certain microorganisms, particularly Pseudomonas aeruginosa. It is composed of a single rhamnose sugar molecule linked to a lipid molecule. Monorhamnolipids exhibit surface-active properties, making them useful in a variety of industrial applications such as enhanced oil recovery, bioremediation, and pharmaceuticals. Research in this area focuses on elucidating the biosynthesis pathways of monorhamnolipids, optimizing production methods, and exploring their potential uses in various industries.
