Parvimonas micra ATCC 33270

Parvimonas micra ATCC 33270 is a Gram-positive, non-motile coccus that exhibits anaerobic growth, thriving in environments devoid of oxygen. This species is classified as a chemoheterotroph, utilizing organic compounds for energy. It is commonly found in multiple habitats, indicating its ecological versatility. The optimal growth temperature for P. micra is 37°C, which aligns with the typical human body temperature, suggesting a potential association with human microbiota. This bacterium possesses a single replicon, indicating a streamlined genomic organization that may contribute to its adaptability in various environments. Notably, P. micra is nonsporulating, which means it does not form spores as a means of survival under adverse conditions. Additionally, this organism is characterized by the presence of flagella, although its non-motility suggests that these structures may not play a role in active movement but could be involved in other cellular processes. The ecological significance of Parvimonas micra lies in its potential role within the human microbiome, particularly in anaerobic environments such as the oral cavity and gastrointestinal tract. Its ability to metabolize organic substrates may contribute to the complex interactions within microbial communities, influencing health and disease states. Understanding the characteristics of P. micra can enhance our knowledge of microbial ecology and the functional roles that anaerobic bacteria play within their respective environments.
