Pseudomonas aeruginosa and its use in a process for the biotechnological preparation of L-rhamnose

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.
