[Amino acid analysis of culture media and autolysates by capillary gas chromatography].

N-heptofluorbutyryl-O-propyl ethers from 20 natural amino acids were analysed on a capillary column Am-Ac by gas chromatography. A high reproducibility of the quantitative estimation of the compounds studied was achieved not only for the standard mixtures but when analysing the amino acid composition of the autolysates of the baker's yeast and cultural media.
