Natural biosurfactant produced by fermentation of Candida bombicola
1) What is Sopolin(Sophorolipids)?
Sopolin is a glycoplipid biosurfactant derived from microorganism, and is a natural biosurfactant produced by fermentation of Candida bombicola. Sopolin is biologically produced by the bioconversion of glucose and plant oil (or its esters) at the stationary phase of fermentation during while glycosidic bond are formed.
2) Sopolin derived from natural products
Natural surfactant produced from fermentation of natural substances including glucose, rapeseed oil, yeast extract (Saccharomyces cerevisiae) and natural substances (GMO free).
3) Chemical Structure of Sopolin
1. Composed of hydrophile (Sophorose) + lipophile (Fatty acid)
2. Non ionic surfactant
3. Mixture of Acidic and Lacton form and varies depending on the fatty acids and acetyl groups of sophorose
4. Ratio of Fatty Acids
- Fatty acid profile of rapeseed oil, a raw material, is similar to that of Sopolin
- Oleic acid is one of the major fatty acids.
