Rhamnolipid - alginate polymer - complex, microbiological process for its production, rhamnolipid - alginate polymer - complex - preparations and their uses

摘要

Rhamnolipid - alginate polymer - complex of building blocks of the structures obtainable by means of a microbiological process under the fermentation of a for the production of rhamnolipid - alginate polymer - complex that is capable of bacterium of the genus pseudomonas, wherein the method includes the steps of that– an aqueous, at least one assimilable carbon source, at least one assimilable nitrogen source and conventional nutrient salts in suitable concentrations and sterilized nutrient medium containing this;– the resulting nutrient medium with a bacterium of the genus pseudomonas inoculated;– the bacterium of the genus pseudomonas, at a ph of - value in the range of 6,5 to 7,5 and at a temperature in the range from 20 to 35°C. is cultured aerobically in a moving submerged culture;– the cells of the bacterium of the genus pseudomonas in a manner known per se from the aqueous medium is separated off; and, optionally– the rhamnolipid - alginate polymer - complexes of the cell-free aqueous medium.
