SUMMARY: Washed cells of micro‐organisms were extracted with 10% acetic acid and the extracts subjected to two‐dimensional paper partition chromatography. With closely related strains within species already defined serologically and physiologically, the patterns of amino acids and peptides revealed by ninhydrin were relatively constant; but with different species variations were noted, even between species hitherto not easy to differentiate.
