Microbial oxidation of short-chain gaseous alkanes (SCGAs, including ethane, propane and butane) are important sinks to mitigate the emission SCGAs atmosphere. 'Candidatus Alkanivorans nitratireducens' has been discovered be capable utilizing nitrate as an electron acceptor anaerobically oxidize these SCGAs. However, little is known about its metabolic diversity in sulfate reduction, despite being widely present both marine freshwater ecosystems. Here, we show that can reduced by 'Ca. A. alternative acceptor. Genomic analysis confirmed genome harbours genes involved reduction. Short-term incubation enriched showed immediate consumption sulfate, suggesting capability utilize Long-term further ability sulfate. rates reduction gradually decreased during long-term incubation, accompanied a deline relative abundance nitratireducens'. After adaptation with sole acceptor, anaerobic partly recovered switching back from nitrate. Overall, this study indicates utilized but not preferred for The findings deepen our understanding on flexibility
