Abstract
Disclosed is a method for separating lycine and L-serine from a solution containing both of them in the dissolved state and, in particular, a reaction solution obtained from a fermentation or enzymic conversion process for the preparation of L-serine by using glycine as the raw material. This method is based on a chromatographic technique utilizing the differential affinity of L-serine and glycine for a strongly acidic ion exchange resin.
