Document Type and Number:
Japanese Patent JP3162224
Kind Code:
B2
Abstract:

PURPOSE: To provide a production method by which a sialic acid can be obtained in high yield without using any expensive natural material.
CONSTITUTION: An acid (a), preferably sulfuric acid, is added to a solution containing colominic acid (b) yielded by a microorganism, in such an amount that the concentration of the acid (a) in the resulting solution is 0.01N to 1.0N. The acid (b) is hydrolyzed at 60-100°C to liberate a sialic acid (c). Under optimal conditions, at least 70% of the acid (b) can be decomposed into the monomer (c).
