DISTRIBUTION OF HYDROXYPOLYAMINES, AMINOPROPYLCADAVERINE, AND SPERMINE IN THERMOPHILIC, HYDROGENOXIDIZING PSEUDOMONADS

Abstract

A slightly thermophilic hydrogen bacterium, "Pseudomonas hydrogenothermophila, " was found to contain 2-hydroxyputrescine, 2-hydroxyspermidine, diaminopropane, putrescine, cadaverine, spermidine, aminopropylcadaverine and spermine. A mesophilic hydrogen-oxidizing pseudomonad, "Pseudomonas hydrogenovora" contained putrescine, 2-hydroxyputrescine, and spermidine. The polyamine distribution pattern of the latter is rather common in the beta subclass of Proteobacteria. The occurrence of 2-hydroxyspermidine, aminopropylcadaverine and spermine is unique in the thermophile.
