Hi Anand, My results and methods are crude but it looks like I'm on the right track. I like the syngas - methane route mentioned above but the process requires some sophisticated and expensive reactors. Its worth looking at manure to house all of it. There is not much in the literature that says man made reactors are more efficient for this process.
I used 32 ounce bottles and filled to bottles with semi solid manure and I had to top off with tap water to make anoxic conditions. To that I added about one ounce of CO2 water, or acetate or a mixture of both. The mixture bottle did not do well on the first round and the acetate alone bottle became toxic and killed all of the methane producing bacteria. The papers say use much less. i used water with O2 in it, thus poisoning the reaction. Thats a good kind of mistake. If acetate is the precursor to methane then CO, taken from syngas, is the precursor to acetate and that test comes next or at least soon. It would be great progress if it worked.
