Rhodopseudomonas palustris strain 2.1.18

Rhodopseudomonas palustris strain 2.1.18 is a Gram-negative, facultative anaerobic bacterium characterized by its bacilli shape and single-cell arrangement. This strain is motile, possessing flagella that enable movement in its environment. It thrives optimally at a temperature of 25°C and is classified as mesophilic, indicating its preference for moderate temperature ranges. This bacterium is found in diverse habitats, including aquatic environments, particularly in stratified aquatic settings, as well as terrestrial locations. Its ability to live freely in these varied environments highlights its ecological versatility and adaptability. The presence of one replicon in its genetic makeup suggests a streamlined genomic organization, which may contribute to its adaptability. Rhodopseudomonas palustris strain 2.1.18 plays a significant role in its ecosystems due to its metabolic capabilities, which allow it to utilize various organic compounds under both aerobic and anaerobic conditions. This flexibility in oxygen requirements enables it to thrive in fluctuating environmental conditions, potentially contributing to nutrient cycling in aquatic and terrestrial ecosystems. The strain's ability to inhabit stratified aquatic environments emphasizes its ecological importance, as it may participate in processes like organic matter decomposition and nitrogen fixation, thereby influencing the productivity and health of its habitats.
