Table 2.
Bacterial growth efficiencies (BGE) in the sediments fed by DOM-1x and DOM-5x, respectively, and individual periods of incubation.
| Experimental phase | BGE (%) | |||
|---|---|---|---|---|
| 1x | 5x | |||
| Sediment at microcosm inlet | Sediment at microcosm outlet | Sediment at microcosm inlet | Sediment at microcosm outlet | |
| Experiment (t0–t171) | 4.7 | 0.5 | ||
| Phase 1 (t0–t46) | 8.9 | 0.8 (1.1)* | ||
| Phase 1B (t28–t46) | 10.4 | 2.5 (2.6)* | ||
| Phase 2A (t46–t77) | 1.2 | 0.4 | ||
| Phase 2B (t77–t126) | 3.0 | 0.2 | ||
| Phase 2C (t126–t171) | 8.9 | 0.4 | ||
*BGE values were calculated from BCP (∆TCC) and DOC mineralization (∆DOC).
