Abstract: Bacterial strains are able to produce rhamnolipids which they release into the culture solution. On use of bacteria of the species Pseudomonas aeruginosa for the fermentation, these microorganisms synthesise rhamnolipids in a concentration of 70-120 g/l of culture solution. The L-rhamnose can be isolated from the culture solution directly by hydrolysis of the rhamnolipids, i.e. without an elaborate removal of the biomass and without isolation of the rhamnolipids before the hydrolysis.

Abstract: The invention relates to polymer conjugates which are reversibly precipitable from aqueous solution and are composed of a carrier polymer which is soluble in aqueous medium and of a catalytically active compound which is chemically bonded thereto. The invention also relates to a process for the preparation of polymer conjugates of this type, and to the use thereof in homogeneous catalysis, especially biocatalysis.

Abstract: The invention relates to a method for the quantitative purification of glycolipids, which is characterised in that the purification of the glycolipids is effected by acidifying the glycolipid-containing solution to pH /= 500 g of the glycolipid-containing phase for sedimentation.

Abstract: HOE 87/F 346 of the disclosure: A method for the aeration, without exit gases, of fermentation media Aeration, without exit gases, of fermentation media is possible by oxygen being transported, with the aid of fluid carrier media, into the fermentation medium and entering the fermentation medium via the liquid/liquid phase boundary, with, subsequently, the fluid carrier medium which has been depleted in oxygen and enriched in carbon dioxide being again enriched with oxygen, without emission of exit gas streams, and with the carbon dioxide which is displaced in this way being desorbed and removed.

Abstract: Cells of E. coli ATCC 11105 immobilised on chitosan are distinguished in the racemate resolution of D,L-2-amino-4-methylphosphinobutyric acid by smaller losses of activity and longer useful lives compared with immobilised acylases.
