US 2003/0148498 A1 · Microorganism overproducing 5'-xanthylic acid

Abstract

The invention relates to microorganism producing 5′-xanthylic acid. More specifically, the invention relates to Corynebacterium ammoniagenes CJXPK001 which is a mutant strain of Corynebacterium ammoniagenes KFCC 10743 having a resistance to 3,4-dehydro-DL-proline. Since Corynebacterium ammoniagenes CJXPK001 of the present invention is resistant to 3,4-dehydro-DL-proline and is not affected by the osmotic pressure caused by the accumulated, highly concentrated solute in the medium, it can produce 5′-xanthylic acid at a high yield and concentration rate.
