The catalytic conversion of methane from natural gas into a readily transportable liquid fuel is a research area that is currently attracting considerable attention. This is a difficult transformation from a thermodynamic viewpoint since methane is a relatively unreactive substance and chemicals derived from methane are substantially more reactive than methane itself. Thus, no industrial process to date has been able to convert methane to liquid products in high yield. One of the more studied process is the oxidative coupling of methane to higher hydrocarbons and olefins. We undertook a program to take advantage of the selectivity already known to exist in a bacterial enzyme system. A group of aerobic soil/water bacteria called methanotrophs can efficiently and selectively utilize methane as the sole source of energy and carbon for cellular growth. The first reaction in this metabolic pathway is the conversion of methane to methanol and is catalyzed by the enzyme methane monooxygenase (MMO). Our work centers on the characterization of the structure/activity relationships of the particulate form of MMO and synthesis and characterization of inorganic/organic chemical models of MMO (both particulate and soluble).
