Culture of a microorganism of the genus Klebsiella Sp., and process for preparing a mixture of carbohydrates with a high content of rhamnose by means of this culture

摘要

The invention relates to biotechnology.; It relates in particular cultures of micro-organism Klebsiella sp. having the characteristics of strain BEC 441 deposited under No. I-714 in the National Collection of Microorganism Cultures of the Pasteur Institute and strains obtained from the CLB 441 strain by mutation, these strains being ca pables produce rhamnose rich polysaccharides by fermentation in a nutrient medium containing assimilable sources of carbon and nitrogen and mineral subs tances.; Application to the production of a mixture of sugars high in rhamnose.
