摘要： The invention relates to a process for quantitatively purifying glycolipids, wherein the purification of the glycolipids is effected by acidifying the glycolipid-containing solution to pH .ltoreq.5.0, then heating the batch to 60.degree. C.-130.degree. C., and then cooling the batch down to .ltoreq.50.degree. C. and centrifuging it at .gtoreq.500 g in order to sediment the glycolipid-containing phase.

摘要： Bacterial strains are capable of the formation of rhamnolipids, which they generate in the culture solution. If bacteria of the type Pseudomonas aeruginosa are employed for the fermentation, these microorganisms synthesize rhamnolipids in a concentration of 70-120 g/l of culture solution. The L-rhamnose can be recovered directly from the culture solution by hydrolysis of the rhamnolipids, i.e. without a complicated separation of the cell material and without isolation of the rhamnolipids before hydrolysis.

摘要： A process for reacting substrates with biocatalysts in a two-phase liquid system disposed in a columnar vessel having a top portion with an exit opening and a first filter disposed therein, a bottom portion with an entrance opening and a second filter disposed therein, a feed line connecting the exit and entrance openings, and a pump disposed in the feed line. The process comprises the steps of: stirring the two-phase liquid in the columnar vessel to accelerate sedimentation and minimize accumulation of the biocatalysts in the top portion of the vessel; selectively controlling the temperature of the two-phase liquid within the vessel; drawing, with the pump, a portion of the two-phase liquid through the exit opening and first filter; and passing the drawn-off portion of the two-phase liquid through the feed line and through the entrance opening and second filter into the vessel to enhance miscibility of the individual phases of the two-phase liquid with the vessel.
