Inoculation date | Feeding mode | Doubling time (h) | Maximum cell density (cells ml−1) |
---|---|---|---|
13 December 2000 | Pulse | 33.3 ± 3.8 | 2.1 × 106a |
16 January 2001 | Pulse | 22.9 ± 5.8 | 1.3 × 107 |
20 February 2001 | Pulse | 23.6 ± 7.9 | 9.8 × 106 |
28 March 2001 | Continuous | 30.5 ± 2.4b | 1.8 × 107 |
9 May 2001 | Continuous | 16.7 ± 3.0 | 1.4 × 107 |
The experiment was stopped before the stationary growth phase was reached.
Doubling time calculated for the period after the Fe(II) supply was restored.
