Title:
5-KETO-D-GLUCONIC ACID METABOLISM DEFICIENT VARIANT
Document Type and Number:
Japanese Patent JPH03164166
Kind Code:
A
Abstract:
NEW MATERIAL:A 5-keto-D-gluconic acid metabolism deficient variant by inducing the variant from a strain belonging to the genus Corynebacterium, capable of producing 2 keto-L-gulonic acid.
EXAMPLE: Corynebacterium sp. (FERM BP-1079).
USE: Producing 2-keto-L-glonic acid from 2,5-diketo-D-gluconic acid without accu mulating 2-keto-D-gluconic acid in a medium.
PREPARATION: A strain [e.g. Corynebacterium sp. (FERM P-2770)] belonging to the genus Corynebacterium, capable of producing 2-keto-L-gulonic acid, is varied by ultraviolet irradiation, etc., and a bacterium not growing in a medium of 5-ketc-D-gluconic acid is selected.
