Proteobacterial Methanotrophs, Methylotrophs, and Nitrogen

  • Lisa Y. SteinEmail author


Research on intersections between single-carbon and nitrogen metabolism have revealed a number of unexpected insights that have expanded our view of how proteobacterial methanotrophs and methylotrophs impact biogeochemical cycles. Aside from assimilating nitrogen as an essential element for cellular growth and metabolism, methanotrophs and methylotrophs metabolize and transform a diversity of inorganic and organic nitrogenous molecules and release reactive nitrogen species as products. Thus, methanotrophs and methylotrophs play a major role in both the global carbon and nitrogen cycles. This chapter outlines the more recent discoveries and unusual nitrogenous molecules and pathways used by proteobacterial methanotrophs and methylotrophs for assimilation, respiration, and regulation of their activities. The role of nitrogen in axenic cultures, complex communities, and bioindustrial applications is discussed.
