(A) Positions of PCR primers for the arxA gene and expected size of the PCR product. (B) Gel images showing the results of PCR with newly designed primers. Samples in lanes are: M, 10 kb DNA ladder as a size marker; (1–2) Jozankei microbial mat; (3) Sulfuritortus calidifontis J1A; (4) Nitrincola lacisaponensis 4CA; (5) Sulfuricella denitrificans skB26; (6) no template control; (7) Mizugaki water; (8) Alkalilimnicola ehrlichii MLHE-1; (9) Sulfuritalea hydrogenivorans sk43H; (10) no template control. In lanes 1 and 2, bands of expected sizes are marked with triangles.
