    Patent number: 4814272
    Abstract: Rhamnolipids with high surface activity are produced micro iologically in high yield per g of dry cell substance using Pseudomonas spec. DSM 2874 in the form of growing, resting and immobilized cell mass in an aqueous medium containing at least one assimilable carbon source at a pH of 6.7 to 7.3 and a temperature of 30.degree. to 37.degree. C. Two new rhamnolipids with only one .beta.-hydroxydecanoic acid residue in the molecule and defined as .alpha.-L-rhamnopyranosyl- and 2-O-.alpha.-L-rhamnopyranosyl-.alpha.-L-rhamnopyranosyl-.beta.-hydroxydeca noic acid with a molecular weight of 334 and 480, respectively, are obtained.
