Summary

, alongside increased expression of genes involved in iron metabolism and methane oxidation coupled with denitrification. Additionally, we observed a shift from the energy-demanding Calvin cycle to the more energy-efficient serine pathway for carbon fixation, promoting the synthesis of glycine and succinyl-CoA, which serve as key precursors for iron storage proteins. These metabolic adjustments highlight a strategy for coordinating both substance and energy metabolism in nitrate-dependent methanotrophic bacteria, thereby enhancing their capacity for simultaneous nitrogen and carbon removal. Our findings reveal that iron may act as a metabolic "switch" in microorganisms, offering new insights into the targeted manipulation of microbial metabolism to maximize their beneficial functions in bo
