Growth parameters of PCC9511 batch cultures shifted from HL to HL+UV during 12 h/12 h L/D cycles.
| Growth Parameters* | Cycle 1 (HL) | Cycle 2 (HL+UV) | Cycle 3 (HL+UV) |
|---|---|---|---|
| μcc (d-1) | 0.69 ± 0.02 | 0.61 ± 0.01 | 0.45 ± 0.00 |
| μnb (d-1) | 0.64 ± 0.05 | 0.45 ± 0.02 | 0.1 ± 0.02 |
| TG1 (h) | 18.0 ± 0.6 | 21.4 ± 0.3 | 29.3 ± 0.2 |
| TS (h) | 3.67 ± 0.14 | 3.72 ± 0.09 | 6.25 ± 0.03 |
| TG2 (h) | 2.33 ± 0.14 | 2.28 ± 0.09 | 1.75 ± 0.03 |
| Sr | 25.0 ± 0.7 | 21.9 ± 0.2 | 21.5 ± 0.1 |
Values shown are averages (± mean deviation) of two biological replicates
*Growth rates per day calculated from: cell cycle data (μcc) or cell numbers (μnb); TG1, TS, TG2: cell cycle phase duration in hours; Sr: rate of synchronization estimated from the ratio (TS+TG2)/(TG1+TS+TG2)
