Data about the amino acid pools, protein amino acids, CO2: O2 ratios, enzyme activities and sensitivities to metal ions and antibiotics, are reported. The utility of an index obtained from the study of the oxygen uptake with various organic-C concentrations and the use of defined media for a more satisfactory discrimination of the various strains, is shown. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-55-2-227
