The present invention relates to a process for selectively producing sophorolactone without use of organic solvent, comprising the steps of: pre-cultivating cells of a Candida species capable of producing sophorolactone, in absence of an oily substrate until a stationary growth phase is obtained, cultivating said pre-cultivated cells in an aqueous medium in the presence of at least one fermentable sugar and substrate; the reaction mixture of sugar, substrate and pre-cultivated cells being present in an amount and conditions such that the cells metabolize the sugar and substrate thereby forming sophorolactone and fatty acid, continuously feeding said substrate to said cells thereby suppressing the formation of fatty acid and keeping fatty acid levels in the reaction mixture below 10 g/l, resulting in the crystallization of at least part of the sophorolactone present in the reaction mixture, warming the reaction mixture to a temperature between 60? C. and 90? C., thereby melting the sophorolactone crystals, allowing the molten sophorolactone to settle and to provide a crude sophorolactone composition, and removing the crude sophorolactone composition from the remainder of the reaction mixture without use of an organic solvent.

The present invention relates to glycosylating polyphenols via biocatalysis. More specifically the present invention discloses particular mutants of the thermostable sucrose phosphorylase derived from the microorganism Thermoanaerobacterium thermosaccharolyticum which efficiently glycosylate polyphenols such as resveratrol.

Surfactants based on a newly discovered class of compounds include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety, and a serine-leucinol dipeptide linked to the lipid oligomer. Such surfactants can be used to create an oil-in-water or water-in-oil emulsion by mixing together a polar component; a non-polar component; and the surfactant. Biosurfactants of the newly discovered class can be made by isolating and culturing a microorganism which produces the biosurfactant, and then isolating the biosurfactant from the culture. A microorganism can be engineered to produce biosurfactant of this newly discovered class by expressing a set of heterologous genes involved in the biosynthesis of the biosurfactant in the microorganism.
