Cellular polyamines of various aerobic Gram-positive cocci and some radio-resistant eubacteria were analyzed.
Staphylococcus and
Micrococcus species except for some spermidine-containing or cadaverine-containing strains were lacking in polyamines.
Planococcus species ubiquitously contained putrescine, spermidine and agmatine.
Marinococcus were divided into two groups, one of which contains no polyamine and another putrescine, spermidine and agmatine. Polyamines were not detected in
Pediococcus, Tetragenococcus, Aerococcus, Alloiococcus, Helcococcus and
Kineococcus species. Spermidine was found in
Stomatococcus mucilaginosus and
Salinicoccus hispanicus while no polyamine was detected in
Salinicoccus roseus. Sporosarcina halophila and
Sporosarcina ureae ubiquitously contained spermidine, however, agmatine was found in the former and spermine in the latter. Polyamine profiles were heterogeneous within aerobic Gram-positive cocci, though each profile was specific for the genera. Different polyamine patterns found in the genera
Marinococcus, Salinicoccus and
Sporosarcina suggest the heterogeneity of these genera. Radio-resistant
Rubrobacter radiotolerans was devoid of polyamines, whereas spermidine was detected in radio-resistant
Deinobacter grandis as well as radio-tolerant
Deinococcus species.
