N2 - A new pmoA gene-based PCR primer set was designed for detection of nitrite-dependent anaerobic oxidation of methane (n-damo) bacteria from four different ecosystems, namely rice paddy soil, freshwater reservoir, reed bed, and sludge from wastewater treatment plant. This primer set showed high specificity and efficiency in recovering n-damo bacteria from these diverse samples. The obtained sequences showed 88-94 and 90-96 % similarity to nucleotide and amino acid sequences, respectively, with the known NC10 phylum bacterium. According to the UniFrac principal coordinates analysis (PCoA), DNA sequences retrieved by the new PCR primer set in this study formed a separate group from the reported sequences, indicating higher diversity of n-damo in the environment. This newly designed PCR primer is capable of amplifying not only the currently known n-damo bacteria but also those that have not been reported, providing new information on the ecological diversity and distribution of this group of microorganisms in the ecosystem.
