Table 2. Ratios of rRNA:rDNA for taxonomic groups in this study.
| Exponential | Near-stationary | Transect | |
|---|---|---|---|
| Ca. P. ubique | 22±16 | 45±17a | 27±17 |
| SAR92 | 20±2 | 16±6 | 9±6 |
| R. pomeroyi | 215±67a | 39±8a | 4±3 |

Culture samples were divided into two periods of growth. Transect samples were from the Delaware estuary. Errors are s.d. For Pelagibacter, SAR92 and Ruegeria, n=6 in each phase of culture growth. For MED152 growth phases, n=4. For transect samples: SAR92, n=4; MED152, n=18; Ruegeria, n=21; Pelagibacter, n=24; and all bacteria, n=24.
