Fatty acids and polar lipids of extremely thermophilic filamentous bacterial masses from two Yellowstone hot springs.
The fatty acid composition of filamentous bacterial masses from two very hot Yellowstone Park springs is not unusual despite the extreme environment. Both populations have a series of C(14) to C(20) straight-chain acids with a maximum at C(18), and a series of saturated iso acids with a maximum at C(17) in one case and C(19) in the other. The fatty acid pattern of this anomalous group of organisms is like that of bacteria but not of blue-green algae. Both populations have similar polar lipids and identical carotenoids. It is speculated that these organisms may be adapted to their high-temperature environment by means of stable lipoprotein membrane systems.
