[Polyamines in representative taxa of coryneform and other bacteria]

The composition of polyamines is studied for the first time in representatives of the genus Micrococcus and taxon "conglomeratus", strains Staphylococcus aureus CCM 209, Deinococcus erythromyxa CCM 706 as well as of Erwinia carotovora ATCC 15713 polyamines, which are not extracted by perchloric acid. Considerable amounts of spermine and rarely of spermidine are revealed in cells of Gram positive microorganisms, that differs them from Gram negative bacteria possessing high concentrations of putrescine, spermidine and their derivatives. A procedure is developed for detection of polyamines in cells of Gram positive microorganisms. It is recommended to use the hydrolysis of their cells by 6N HCl for 4 at 120 degrees C or for 8-10h at 100 degrees C with the subsequent electrophoretic separation. Putrescine, as well as comparable with it amount of agmatine and spermidine traces are found in Erwinia carotovora ATCC 15713 cell hydrolyzates, whereas putrescine and agmatine traces are found in perchloric extracts of intact cells. Spermine is not observed in the cells. The binding of polyamines with biopolymers of cells of Gram positive bacteria and their difference by the given character from the Gram negative procaryotes are under discussion.
