Porphyromonas gingivalis SJD12

Porphyromonas gingivalis SJD12 is a Gram-negative, rod-shaped bacterium that is nonsporulating and thrives in anaerobic conditions. This microbe is typically associated with host environments, indicating its adaptation to living within specific biological systems, particularly in the human oral cavity where it is known to be part of the subgingival microbiota. Its optimal growth temperature is 37.0°C, aligning with the physiological temperature of the human body, which further suggests its role in host-associated habitats. The anaerobic nature of P. gingivalis SJD12 highlights its dependence on low-oxygen environments, which is characteristic of many oral bacteria that inhabit periodontal pockets. As an anaerobe, it likely utilizes fermentation pathways to generate energy in the absence of oxygen, which may contribute to its ecological niche in the oral biofilm. Understanding the growth requirements and habitat preferences of Porphyromonas gingivalis SJD12 may provide insights into its interactions within the oral microbiome and its potential implications in oral health and disease. The ability of this bacterium to thrive in anaerobic conditions underscores the importance of oxygen depletion in the development and maintenance of polymicrobial communities in host-associated environments.
