Comparison of DNA concentrations in anaerobic sludges from WWTP and OFMSW samples in the two experimental line
| DNA µg/g of weighted sample ± SD | ||
|---|---|---|
| WWTP | ||
| Fresh samples | Frozen samples | |
| A samples | 246.1 ± 107.7 | 89.6 ± 48.2 |
| B samples | 182.0 ± 65.2 | 75.5 ± 35.4 |
| C samples | 103.2 ± 44.6 | 28.3 ± 12.4 |
| D samples | 143.9 ± 64.9 | 43.5 ± 21.1 |
| All samples | 168.8 ± 89.0 | 59.2 ± 39.7 |
| OFMSW | ||
|---|---|---|
| Days elapsed | E sample | F sample |
| 1 | 21.6 | 32.36 |
| 19 | 9.16 | 22.8 |
| 28 | 13.64 | 35.88 |
| 29 | 4.64 | 12.36 |
| 21 | 7.32 | 15.84 |
| 27 | 4 | 2.36 |
The mean values and SD are reported, based on 10 replicates for each type of samples, concerning WWTP samples. For OFMSW experimental line, only two samples were available, so SD was not calculated, since E and F samples were independent sludge samples
