Blass and Macheboeuf reported that they had isolated α-aminoadipic acid from cholera Vibrio (1). On repeating the experiment later, they tested the purity of the isolated product by means of paper chromatograms developed with phenol and retracted their earlier claim (2). However, Borsook et al. found that α-aminoadipic acid and glutamic acid gave the same spot on two-dimensional paper chromatograms developed with phenol and δ-collidine (3). The retraction of Blass and Macheboeuf was therefore based on a method which does not differentiate between the two dicarboxylic amino acids. By using the starch chromatographic method of Stein and Moore (4), Borsook et al. were able to separate α-aminoadipic acid from other amino acids, including glutamic acid (3). In this present study an attempt is made by the same technique to determine whether α-aminoadipic acid is present in the cholera Vibrio.
