Methane to liquid fuel

http://ens-newswire.com/2013/01/04/biotech-bacteria-could-convert-methane-to-liquid-diesel/

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.

Methane-oxidizing bacteria for biotechnology

http://onlinelibrary.wiley.com/doi/10.1002/elsc.200900093/abstract

This paper describes a bacterium that grows on methane and produces copious amounts of polyhydroxy butyrate.

This page contains notes from a workshop at which approaches were discussed for converting methane to liquid biofuels, largely by biological mechanisms.

Methanotrophic microbiomes

https://biblio.ugent.be/publication/3166868

This page links to a dissertation focused on studies of methanogenic communities with the goal of mitigating against atmospheric methane release.

Methylococcus capsulatus

http://microbewiki.kenyon.edu/index.php/Methylococcus_capsulatus

Methylococcus capsulatus is a methanotrophic bacterium that has been well studied and is one of two major experimental model systems for understanding the biochemistry of methanotrophy.

Methylosinus trichosporium OB3b: BioCyc

http://biocyc.org/MOB3B/organism-summary?object=MOB3B

Methylosinus trichosporium is a methanotrophic bacterium that has been well studied and is one of two major experimental model systems for understanding the biochemistry of methanotrophy. This BioCyc page contains metabolic reconstruction information derived from the genome-sequencing project for this organism.

Non-methanotroph in methanotroph environment

http://www.ncbi.nlm.nih.gov/pubmed/23765894

This paper shows methane oxidation by a non-methanotrophic bacterium containing an alkane monooxygenase enzyme.

Methanotroph ecology for gas prospecting

http://www.ncbi.nlm.nih.gov/pubmed/20107985

Deoxyribonucleic acid sequencing can be used to identify methanotrophic community signatures that might be indicative of natural gas being below the surface in a given region.

Methylmicrobium buryatense 5G genome

http://genomea.asm.org/content/1/4/e00053-13.full

Methylmicrobium buryatense 5G is a fast-growing methanotrophic bacterium, and thus it may have commercial value; this study describes its genome sequence.

Methane biofiltration systems

http://www.ucalgary.ca/mehrotra/files/mehrotra/2011-Hettiarachchi-Hettiaratchi-Mehrotra-Kumar-EnvironmentalPollution.pdf

Environmental methane releases are of growing concern because of increases in oil extraction from oil sands and via hydraulic fracturing. One method of detailing with methane emissions where gas harvesting is not possible is to use methane biofilters.
