Glycolipid biosurfactants

Among biosurfactants, glycolipids are the earliest and most in-depth researched, and they are also the first type of biosurfactant to realize industrial fermentation. There are currently two main types, Sophorolipid and Rhamnolipid.

The initial strains of both glycolipids originate from the natural environment, and there are several natural strains that can metabolize glycolipid surfactants. After continuous optimization and screening, the two strains currently most widely used in industrial applications are: Starmerella bombicola, which produces sophorolipids, and Pseudomonas aeruginosa, which produces rhamnolipids.。

Molecular structure of glycolipid surfactants

Glycolipid surfactants are composed of hydrophilic "sugar" and hydrophobic "carbon chains". Due to different types of sugar groups, different glycolipid products can be named, such as sophorosyl sophorolipids and rhamnosyl rhamnolipids. Because of the different number of sugar rings, differences in the length and degree of unsaturation of the carbon chain, and other groups that may be produced at different positions, many structural variants have been derived. Each glycolipid class has dozens of structural variants.


Comparison of the differences between sophorolipids and rhamnolipids

The following table is a comparison of the differences between sophorolipids and rhamnolipids. Unspecified indicators are the same or similar. Due to different bacterial strains, formulas and production processes from different manufacturers, the content listed in this table only applies to DG BIO's glycolipid-related products.
