چکیده
With the recent drop in natural gas prices in the United States, there is heightened interest to use methanotrophic bacteria to produce commercial products such as liquid fuels. This project was recently funded to explore this paradigm. This paper describes a bacterium that grows on methane and produces copious amounts of polyhydroxy butyrate.

Differential Transcriptional Activation of Genes Encoding Soluble Methane Monooxygenase in a Facultative Versus an Obligate Methanotroph
Methanotrophs are a specialized group of bacteria that can utilize methane (CH₄) as a sole energy source. A key enzyme responsible for methane oxidation is methane monooxygenase (MMO), of either a soluble, cytoplasmic type (sMMO), or a particulate, membrane-bound type (pMMO). Methylocellasilvestris BL2 and Methyloferulastellata AR4 are closely related methanotroph species that oxidize methane v...
متن کاملEstimation of methanotroph abundance in a freshwater lake sediment.
The numbers of methane-oxidizing bacteria (methanotrophs) in the sediments of Lake Washington were estimated using three culture-independent methods. Quantitative slot-blot hybridizations were performed with type I and type II methanotroph-specific probes. These data were compared to data from quantitative hybridizations using a pmoA-specific probe and a eubacterial probe. From the combined hyb...
متن کاملPotential of Immobilized Whole-Cell Methylocella tundrae as a Biocatalyst for Methanol Production from Methane.
Methanol is a versatile compound that can be biologically synthesized from methane (CH4) by methanotrophs using a low energy-consuming and environment-friendly process. Methylocella tundrae is a type II methanotroph that can utilize CH4 as a carbon and energy source. Methanol is produced in the first step of the metabolic pathway of methanotrophs and is further oxidized into formaldehyde. Sever...
متن کاملDraft Genome Sequence of the Moderately Halophilic Methanotroph Methylohalobius crimeensis Strain 10Ki
Methylohalobius crimeensis strain 10Ki is a moderately halophilic aerobic methanotroph isolated from a hypersaline lake in the Crimean Peninsula, Ukraine. This organism has the highest salt tolerance of any cultured methanotroph. Here, we present a draft genome sequence of this bacterium.
متن کاملComplete genome sequence of Methylocystis sp. strain SC2, an aerobic methanotroph with high-affinity methane oxidation potential.
Methylocystis sp. strain SC2 is an aerobic type II methanotroph isolated from a highly polluted aquifer in Germany. A specific trait of the SC2 strain is the expression of two isozymes of particulate methane monooxygenase with different methane oxidation kinetics. Here we report the complete genome sequence of this methanotroph that contains not only a circular chromosome but also two large pla...
