Summary:
- This article reports the discovery of a new species of bacteria, Candidatus Desulfocapsa sulfatarsenicans, found in the extreme environment of a volcanic hot spring in Yellowstone National Park.
- The researchers used a combination of genomic and metabolic analyses to characterize this novel bacterium, which is capable of oxidizing arsenic and reducing sulfate, allowing it to thrive in the arsenic-rich, sulfur-rich, and high-temperature conditions of the hot spring.
- The findings provide insights into the microbial diversity and adaptations in extreme environments, and highlight the potential of such environments to harbor previously undiscovered microorganisms with unique metabolic capabilities.
