About Arpita Bose's Work

Microbes drive global biogeochemical cycles. Pervasive in every environment, microbially mediated reduction-oxidation reactions dominate matter and energy flow throughout the biosphere. Most microbes use soluble electron donors and acceptors, but some can also use solid phase conductive substances (SPCS). This process is called extracellular electron transfer or EET. EET refers to the use of SPCSs as both electrons acceptors (reductive EET) and electron donors (oxidative EET). My research focuses on oxidative EET, a phenomenon that has come to fore only recently and changes our perception of the role of microbes in nature. My research aims to understand oxidative EET, determine its influence in nature, and use this knowledge to provide solutions to global issues such as the energy crisis and climate change.
