Generation of materials with enhanced hydrogen content from anaerobic microbial consortia

An isolated microbial consortia for biogenically producing methane from a larger hydrocarbon, the consortia comprising:

• a first microbial consortium to convert a larger hydrocarbon into a product containing one or more intermediate hydrocarbon compounds;
• a second microbial consortium, comprising one or more species of Pseudomonas, to convert the intermediate carbon compounds into a product comprising carbon dioxide and molecular hydrogen;
• and
• a third microbial consortium to convert the carbon dioxide and molecular hydrogen into methane and water.

Isolated microbial consortia for anaerobic production of methane from a larger hydrocarbon, the consortia comprising:

• a first microbial consortium, comprising one or more species of Pseudomonas, to convert the larger hydrocarbon to form a product comprising smaller hydrocarbons;
• and
• a second microbial consortium to convert at least a portion of the smaller hydrocarbons to form a product comprising acetate;
• a third microbial consortium to convert said acetate to form methane and water.
