Cecembia calidifontis str. DSM 21411

Cecembia calidifontis str. DSM 21411 is a Gram-negative, rod-shaped bacterium that exhibits aerobic metabolism and thrives at an optimal growth temperature of 45.0°C. This thermophilic organism does not form spores, which suggests that it relies on other mechanisms for survival in potentially adverse environmental conditions. The Gram-negative nature of Cecembia calidifontis indicates that it possesses a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides, which may contribute to its resilience in high-temperature environments. As an aerobic bacterium, it requires oxygen for its metabolic processes, positioning it within ecosystems where oxygen is readily available, such as hot springs or thermally enriched soils. The specific adaptation to higher temperatures may confer a competitive advantage in certain niches, allowing Cecembia calidifontis to utilize organic substrates efficiently in thermophilic habitats. Understanding the physiological traits of this microbe can provide insights into its potential roles in biogeochemical cycles, particularly in thermally active environments where microbial activity is critical for nutrient degradation and turnover.
