Abstract (EN):
Two strains of Rhodothermus marinus from Iceland, three strains of Rhodothermus sp. from the Azores, and 'Thermus thermophilus' HB-8 were grown in basal salt medium 162 with yeast extract plus tryptone (medium A); yeast extract plus sodium glutamate (medium B); yeast extract alone (medium C) and glutamate alone (medium D). In medium A and C, branched-chain iso-C15 and iso-C17 fatty acids were the major fatty acids, iso-C16 and normal-chain fatty acids were minor components. In medium B, the relative proportion of iso-C16 increased to high levels, and was the major component of the Azorean Rhodothermus strains. In medium D, with glutamate as sole source of carbon and energy, normal-chain C16 constitued the major component, and normal-chain fatty acids reached about 50% of the total fatty acids.
