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.
尽管环境极端,但来自黄石公园两个非常炎热泉水中的丝状细菌群体的脂肪酸组成并无异常。这两个群体都有一系列碳数为14至20的直链酸,其中碳数为18时含量最高,还有一系列饱和异酸,在一种情况下碳数为17时含量最高,在另一种情况下碳数为19时含量最高。这一异常生物群体的脂肪酸模式与细菌相似,而与蓝藻不同。两个群体都有相似的极性脂质和相同的类胡萝卜素。据推测,这些生物可能通过稳定的脂蛋白膜系统来适应其高温环境。
