Textbooks on methane-metabolising organisms might have to be rewritten after researchers in a University of Queensland-led international project today (23 October) announced the discovery of two new organisms.
Deputy Head of UQ's Australian Centre for Ecogenomics in the School of Chemistry and Molecular Biosciences Associate Professor Gene Tyson said these new organisms played an unknown role in greenhouse gas emissions and consumption.
"We sampled the microorganisms in the water from a deep coal seam aquifer 600m below the earth's surface in the Surat Basin, near Roma, Queensland, and reconstructed genomes of organisms able to perform methane metabolism," Associate Professor Tyson said.
"Traditionally, these type of methane-metabolising organisms occur within a single cluster of microorganisms called Euryarchaeota.
"This makes us wonder how many other types of methane-metabolising microorganisms are out there?"
Dr Tyson's group discovered novel methane metabolising organisms belonging to a group of microorganisms, called the Bathyarchaeota - an evolutionarily diverse group of microorganisms found in a wide range of environments, including deep-ocean and freshwater sediments.
"To use an analogy, the finding is like knowing about black and brown bears, and then coming across a giant panda," Dr Tyson said.
"They have some basic characteristics in common, but in other ways these they are fundamentally different.
"The significance of the research is that it expands our knowledge of diversity of life on Earth and suggests we are missing other organisms involved in carbon cycling and methane production."
The discovery of the novel methane-metabolising microorganisms was made using techniques that sequence DNA on a large scale and assemble these sequences into genomes using advanced computational tools, many of which were developed at The Australian Centre for Ecogenomics over the past 24 months.
The research, titled Methane metabolism in the archaeal phylum Bathyarchaeota revealed by genome-centric metagenomics, was published in Science.

Methane Organisms ping!...................
Yeah, but they'll smell really bad. BTT
Methane is odorless...................it’s the ‘additives’ you smell.....................
Kill them, kill them all!!!
They are eating our fuel!!!
Dr. Tyson’s research is going to improve our understanding the mechanism of global warming!
Yep. Just like propane. The additives are there to help people notice if there’s a leak.
These things are still DNA/RNA creatures.
We haven’t been able to take the chemical origin of life back any further — nothing in the present, and nothing in the fossil record.
But something had to come earlier, since DNA and RNA are complex molecules.
Maybe something on Mars will give us a hint.
LOL!!...........They must be liberals.......................
I think these things are pretty dangerous. One almost destroyed the Enterprise once.
Hah, I could have saved them a lot of money. Rather than look deep beneath the ocean, should just check the intestinal tracts of those of us on the other side of 55.
Do they metabolize it into 100 octane or what?
Methane organisms?
You mean Hillary, I take it?
Smell is ‘how’ they communicate.
Just because we can’t smell it, doesn’t mean that methane producing microbes can’t.
My old man once stated that the solution to the Middle East problem is to develop a microorganism that converts crude oil into sand, and to nuke the whole of Saudi Arabia with it.
It`s called mercaptan: http://www.mudomaha.com/blog/why-does-natural-gas-smell-rotten-eggs-2
Thanks Red Badger.

New recruits for the Occupy Movement?
Put a tiny drop of t-butyl mercaptan underneath somebody’s front porch and watch the fun begin.
