Which of the following electron acceptor that is used by the bacteria is mainly responsible for marine corrosion?
In microbiology, microbial physiology dictates that growth regulation and host interactions follow molecular programs. Therefore SO ₄ ⁻² is correct as it corresponds to prokaryotic strategies, supported by mechanistic studies and conserved across related systems.
Ref: Madigan et al., Brock Biology of Microorganisms, 15th Edition, Chapter 13, Virology, explains viral replication and virus-host interactions detailing microbial genetics.
