Carboxydothermus pertinax

Carboxydothermus pertinax is a rod-shaped, strictly anaerobic bacterium that thrives at an optimal temperature of 45.0°C. As a member of the microbial community, C. pertinax is capable of utilizing carbon monoxide as a carbon and energy source, which suggests its potential involvement in biogeochemical cycles, particularly in environments rich in organic material and carbon compounds. The adaptation to an anaerobic lifestyle indicates that C. pertinax occupies environments where oxygen is limited or absent, such as deep-sea hydrothermal vents, anoxic sediments, or other geothermal habitats. Its ability to metabolize carbon monoxide may also contribute to the detoxification of this gas in its native environment, thereby influencing local carbon cycling dynamics. Moreover, the thermal preference of C. pertinax highlights its potential role in high-temperature ecosystems, where it may interact with other extremophiles, contributing to microbial consortia that thrive under similar conditions. The physiological traits of C. pertinax underscore its importance in understanding microbial ecology in extreme environments and its potential applications in biotechnological processes that exploit anaerobic metabolism and carbon monoxide utilization.
