- •
A survey was performed on microbial communities in oil reservoirs with different temperatures.
- •
The survey focuse on genes of cbbM, cbbL, fthfs, [FeFe]-hydrogenase encoding gene and mcrA.
- •
A rich diversity of functional genes involved in CO2 fixation and conversion of CO2 to CH4 was found.
- •
The predominant methanogens were hydrogenotrophic CO2 reducing ones.
- •
The results implies high potential for in situ microbial fixation and conversion of CO2 into CH4.
