Diversity of Uncultured Magnetospirillum sp. from the Sediments of South Kerala Sedimentary Basin, India

Thermophilic Magnetotactic Bacteria from Mickey Hot Springs, an Arsenic-Rich Hydrothermal System in Oregon

“…Magnetotactic bacteria (MTB) are found in a variety of aquatic sediments such as marine and freshwater environments all over the world. − MTB play an important part in the geochemical cycling of elements such as carbon, iron, nitrogen, phosphorus, and sulfur. − They are known to occupy specific niches (e.g., low O 2 concentrations) within their habitat using chemotaxis and magnetotaxis to find optimal growth conditions. ,,− Different chemicals in the environment such as iron, nitrate, oxygen, and sulfur can impact the type of MTB that exist at a specific environmental site. ,− Previous studies have described the metabolic diversity of MTB within various habitats and confirm that these organisms play important biogeochemical roles in their environment. ,,,,, For example, Araujo et al (2016) used a comprehensive genomic approach to characterize Magnetofaba australis strain IT-1 and demonstrate that it is capable of nitrogen fixation, sulfur oxidation, and reduction and synthesis of intracellular phosphate-rich granules . In another paper, Rivas-Lamelo et al (2017) demonstrated that MTB belonging to the Magnetococcaceae family play an important role in the phosphorus cycle in Lake Pavin (France) …”
