Ferroplasma is a genus of microorganisms known as archaea, which are single-celled organisms distinct from bacteria and eukaryotes. These extremophiles thrive in high-temperature environments, such as hot springs and deep-sea hydrothermal vents, where they can survive extreme conditions. Ferroplasma is notable for its ability to oxidize iron, which plays a crucial role in its energy metabolism. This genus is characterized by its unique cell structure, lacking a traditional cell wall, and instead having a membrane composed of lipids. Ferroplasma species are often studied for their potential applications in biotechnology and bioremediation, as they can help in the extraction of metals and the breakdown of pollutants in harsh environments.
