Thermotoga maritima, a thermophilic eubacterium, is motile at temperatures ranging from 50 to 105 degrees C. The cells are propelled by a single flagellum which most of the time spins clockwise. Changes in the swimming direction ("tumbles") are achieved by short reversals of the direction of filament rotation. The average speed of swimming cells depends on the temperature, reaching a maximum value of about 60 microns/s at 85 degrees C. The cells show a thermotactic response to temporal temperature changes. When the temperature is raised, the rate of tumbles is increased, while decreasing temperature decreases the tumbling rate.
嗜热栖热菌是一种嗜热真细菌,在50至105摄氏度的温度范围内具有运动能力。细胞由一根单一的鞭毛推动,鞭毛大部分时间顺时针旋转。游泳方向的改变(“翻滚”)是通过细丝旋转方向的短暂反转来实现的。游泳细胞的平均速度取决于温度,在85摄氏度时达到约60微米/秒的最大值。细胞对温度的时间变化表现出趋温反应。当温度升高时,翻滚速率增加,而温度降低则降低翻滚速率。
