a Anaerobic archaeal oxidation of methane; b dissimilatory sulfate reduction; c archaeal methanogenesis; d anaerobic degradation of alkanes by bacteria. Red font indicates that not all MAGs retrieved include the gene (numbers of MAGs with the corresponding gene indicated in parentheses). The percentages between brackets indicate the estimated completeness of the corresponding MAGs.
