Rhodospirillum rubrum S 1, S1

Rhodospirillum rubrum S1 is a Gram-negative, photolithotrophic bacteria that functions as a photoautotroph, utilizing light as its primary energy source. It is characterized by its spiral shape (spirilla) and exhibits mobility due to the presence of flagella. R. rubrum S1 is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic conditions. The optimal growth temperature for this species is 25°C, placing it within the mesophilic temperature range. Genetically, R. rubrum S1 has three replicons, which may contribute to its adaptability and genetic diversity. This organism is noted to be free-living, suggesting it does not rely on a host for survival. The accessions associated with R. rubrum S1 include CP077803.1, CP077804.1, and CP003046.1, which provide extensive genomic information that can be useful for further studies. In an ecological context, the ability of R. rubrum S1 to utilize light for energy while also being capable of surviving in various oxygen conditions highlights its potential role in diverse environments. This adaptability may allow it to participate in biogeochemical cycles, particularly in environments where light is available, and contribute to the cycling of nutrients in ecosystems.
