Abstract
ACCORDING to our earlier reports1, the legume bacteria split off quantitatively one of the carboxyl groups from l-aspartic acid forming β-alanine, HO2C.CH2.CH(NH2).CO2H→HO2C.CH2.CH2NH2 + CO2. The reaction was at first accomplished only with living bacteria. We have now succeeded in observing it also in the presence of toluene with the same bacteria. The bacterial suspension, which had been kept 24 hours under toluene, split off carbon dioxide forming β-alanine in an aspartic acid solution (pH 7) in the presence of toluene.
