A method for producing methane by biological conversion of carbon dioxide, performed by means of a symbiosis between one or more methane-generating bacteria and: (i) one or more hetero-autotrophic cyanobacteria and/or microalgae, or (ii) one or more sulfobacteria and/or acetobacteria, wherein said hetero-autotrophic cyanobacteria and/or microalgae, or said sulfobacteria and/or acetobacteria, produce the molecular hydrogen required for the conversion of carbon dioxide into methane performed by said methane-generating bacteria. |
