Halanaerobium congolense strain UTICA-S4D12

Halanaerobium congolense strain UTICA-S4D12 is an anaerobic bacterium isolated from a produced water sample associated with the Utica shale, specifically from hydraulically fractured shale wells and oil reservoirs. This strain thrives in deep subsurface shale environments where oxygen levels are minimal or absent, making it well-adapted to the anaerobic conditions typical of these habitats. A notable characteristic of Halanaerobium congolense UTICA-S4D12 is the presence of flagella, which may facilitate motility within its environment, potentially aiding in nutrient acquisition and colonization of specific niches within the shale. Additionally, the strain possesses a single replicon, indicating a streamlined genetic organization that might contribute to its adaptability and survival in complex subsurface ecosystems. The genomic sequence of Halanaerobium congolense UTICA-S4D12 is cataloged under the accession number SOAA00000000.1, providing a basis for further studies on its metabolic pathways and ecological roles. This bacterium's presence in produced water samples highlights its potential importance in biogeochemical cycles within oil reservoirs and suggests that it may play a role in the degradation of organic compounds in anaerobic environments. Overall, Halanaerobium congolense strain UTICA-S4D12 exemplifies the diversity and adaptability of microbial life in extreme environments, particularly in relation to human activities such as hydraulic fracturing, which can alter subsurface ecosystems.
