| titleOfInvention | A kind of method for separating and purifying biosurfactant rhamnolipid |
| abstract | The invention discloses a method for separating and purifying biosurfactant rhamnolipid. The method comprises the following steps of: centrifuging a rhamnolipid fermentation broth to obtain a supernatant, adding acid to adjust pH, then centrifuging to obtain a precipitate, and resuspending the precipitate After washing, the obtained supernatant is adjusted to pH with acid, then centrifuged to collect the precipitate, extracted with an organic solvent, and finally back-extracted with a phosphate buffer solution to obtain a purified rhamnolipid solution. The invention improves the existing rhamnolipid separation and purification method and optimizes the extraction process, thereby increasing the purification concentration of the rhamnolipid. |
