| AZM14 | 1.46 × 105 | 31.3 | 68.7 | 0.7 |
| AZM14 (mat) | 96.5 | 3.5 | 0.9 | |
| AZM16 | 4.96 × 104 | 87.7 | 12.3 | 1.4 |

| AZM19 | 6.60 × 105 | 93.8 | 6.2 | 1.2 |
a
ND indicates that the value is below the detection limit (<102 copies).
b
The real-time PCR for Archaea did not yield positive results for AZM13 (see Results for details).
