Hi Dr Karve, Not sure you are directing your question to the right forum, but as it's CO2 and methane, guess it qualifies, but never thought my own interest in this humble cell form would be useful to anyone(:-)
Archaea having been around for 3-4 billion years are the ultimate colonist of any environment, survival being that they arrive at their destination from where ever they come from. Even if there was not the chemistry present to feed directly, they can also take in energy from Sunlight and convert this to feed. Mutation is rapid, given the environmental chemistry would also changing around them over a few million years or so. Time doesn't seem to matter and they keep multiplying to suit their environment. They can now be found in just about every thing on this planet,so I'm sure carbonic acid was considered ideal nutrient. Given that your interest is of their participation in digestive processes and the evolution of methane, one can only guess that the building blocks allowing their evolution branching into bacteria one way, and eucaryota the other, they had plenty of places to turn host nutrient into methane. My own interest is their function within the human gut, evidenced by their methane production and distinctive smell, and how they might be involved with the matrix of peptides on which warm blooded cells of life forms build. It may be better to discuss this privately rather than be off topic. Regards, Doug Williams, Fluidyne.
