摘要： A method for the production of a rhamnolipid. The method includes culturing in a fermentation medium an organism capable of producing a rhamnolipid to form a fermentation broth comprising at least one rhamnolipid and having a pH>5; extracting at least one lipophilic impurity from said fermentation broth; acidulating said fermentation broth to form an aqueous medium of pH

摘要： Methods for production of a bioproduct with a microorganism and selective extraction of bioproducts from a fermentation broth. The methods may include mixing a carbon source, a nitrogen source, and an extractant-depleted raffinate to form a fermentation medium, and fermenting the medium with a microorganism to form a fermentation broth having at least one bioproduct. The bioproduct may be extracted from the fermentation broth with an extractant comprising an olefin to form an extract and a raffinate, and the extract may be further separated from the raffinate. The bioproduct may then be separated from the extract, and the extractant may be separated from the raffinate to regenerate the extract-depleted raffinate.

摘要： Disclosed are methods for making one or more bioproducts such as isoprene derivatives, fatty acids, fatty acid derivatives, fatty alcohols, fatty alcohol derivatives, mixtures thereof, and compositions having one or more such bioproducts with microorganisms and for separating the bioproduct(s) or bioproduct composition(s). The methods include providing an extractant having a solvent with a boiling point at atmospheric pressure of less than 20° C.; feeding an aqueous suspension of cells that have produced the bioproduct(s) into a pressurized column; feeding the extractant into the pressurized column; removing an extract having the extractant and the bioproduct(s) from said pressurized column; and separating the extractant from the removed extract to obtain a separated oil-soluble composition having the bioproduct.

The methods may include mixing a carbon source, a nitrogen source, and an extractant-depleted raffinate to form a fermentation medium, and fermenting the medium with a microorganism to form a fermentation broth having at least one bioproduct. The bioproduct may be extracted from the fermentation broth with an extractant comprising an oxygenated organic compound and a hydrocarbon to form an extract and a raffinate, and the extract may be further separated from the raffinate. The bioproduct may then be separated from the extract, and the extractant may be separated from the raffinate to regenerate the ex tract-depleted raffinate.
