An extremely halophilic archaebacterium Halobacterium cutirubrum was demonstrated to be devoid of any polyamine except agmatine when grown in a synthetic medium with no exogenous polyamines. Decarboxylation activities of homoarginine and canavanine as well as of arginine were shown to be present in cell lysates of 5 strains of extreme halophiles examined. H. halobium R1 was shown to have an additional pathway to synthesize agmatine from glutamic acid.
