Metabolic Regulation of "Ca. Methylacidiphilum Fumariolicum" SolV Cells Grown Under Different Nitrogen and Oxygen Limitations.

ABSTRACT: Aerobic methanotrophic bacteria can use methane as their sole energy source. The discovery of "Ca. Methylacidiphilum fumariolicum" strain SolV and other verrucomicrobial methanotrophs has revealed that the ability of bacteria to oxidize CH(4) is much more diverse than has previously been assumed in terms of ecology, phylogeny, and physiology. A remarkable characteristic of the methane-oxidizing Verrucomicrobia is their extremely acidophilic phenotype, growing even below pH 1. In this study we used RNA-Seq to analyze the metabolic regulation of "Ca. M. fumariolicum" SolV cells growing at μ(max) in batch culture or under nitrogen fixing or oxygen limited conditions in chemostats, all at pH 2. The analysis showed that two of the three pmoCAB operons each encoding particulate methane monoxygen
