Lumen Boundless Microbiology. «Anaerobic Respiration-Electron Donors and Acceptors in Anaerobic Respiration». courses.lumenlearning.org(en inglés). Boundless.com. Consultado el 19 de noviembre de 2020. «Anaerobic respiration is the formation of ATP without oxygen. This method still incorporates the respiratory electron transport chain, but without using oxygen as the terminal electron acceptor. Instead, molecules such as sulfate (SO42-), nitrate (NO3–), or sulfur (S) are used as electron acceptors».
