MEL
Characteristics
- 1. A biosulfactant, one of glycolipids, produced from plant oil by yeast
(Pseudozyma sp.) - - Hydrophilic part : mannose and erythritol
- - Hydrophobic part : fatty acid
- 2. An eco-friendly and human-suitable material
- - Non-toxicity
- - High biodegradability
- - High surface activity
- - High emulsification activity
- - High thermal stability
- - Low CMC value

- CMC value was measured with purified biosurfactant
- Emulsification activity was measured against hydrocarbons with crude biosurfactant at a concentration of 0.1g/l
- Stabilities were determined by measuring the surface tension of biosurfactant solution
- Salt resistance were determined by measuring emulsification activity
- Toxicity was determined as the concentration to inhibit the 50% of mouse fibroblast cell L929
