Title:
BIOLOGICAL PRODUCTION OF ALPHA-HYDROXY-4-METHYLTHIOBUTYRIC ACID
Document Type and Number:
Japanese Patent JPH0440898
Kind Code:
A
Abstract:
PURPOSE: To produce α-hydroxy-4-methylthiobutyric acid industrially and advanta geously, by using a bacterium having hydrolyzing activity of α-hydroxy-4- methylthiobutyronitrile.
CONSTITUTION: α-Hydroxy-4-methylthiobutyronitrile is converted into α- hydroxy-4-methylthiobutyric acid by hydrolysis reaction by action of bacterium. A bacterium belonging to the genus Caseobacter, Pseudomonas, Alcaligenes, Corynebacterium or Brevibacterium, Nocardia, Rhodococcus or Arthrobacter may be cited as the bacterium used.
