Comparison of ICP values measured via photometry and flow cytometry for different growth phases during yeast propagation
| Growth phase | ICP method | Mean ICP value ± SDa | Coefficient of variation (%) |
|---|---|---|---|
| Lag | Photometer | 5.83 ± 0.09 | 1.48 |
| Cytometer | 6.61 ± 0.03 | 0.49 | |
| Exponential | Photometer | 6.13 ± 0.07 | 1.08 |
| Cytometer | 6.83 ± 0.03 | 0.40 | |
| Stationary | Photometer | 6.07 ± 0.08 | 1.28 |
| Cytometer | 6.77 ± 0.03 | 0.44 |

Arithmetic means were calculated from six independent replications. Mean ICP values from photometry are means of duplicate readings. Mean ICP values from flow cytometry distributions are calculated as the geometric mean.
