| Abstract: | 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. |
