Sulfate-reducing microorganisms are common in anoxic environments and represent an important link between the sulfur and carbon cycles. Here, Dyksma & Pester show that microbial sulfate reduction and aerobic respiration are not mutually exclusive in the same organism, sulfate reducers can mineralize organic polymers, and anaerobic mineralization of complex organic matter is not necessarily a multi-step process.
