Table 1. Growth parameters of Prochlorococcus with or without Alteromonas under ambient (~400 p.p.m.) or elevated (~800 p.p.m.) CO2 regimes.
CO2 treatment | m (day−1) | μ (day−1) | L (day) | D |
---|---|---|---|---|
Ambient | 0.353±0.040 | 0.440±0.023 | 2.21±1.38 | 0.223±0.165 |
Elevated | 0.187±0.041 | 0.426±0.071 | 10.14±3.53 | 0.688±0.164 |
Ambient axenic | 0.048±0.060 | 0.219±0.098 | 9.73±10.82 | 0.539±0.286 |
Elevated axenic | 0.027±0.086 | 0.095±0.124 | 4.57±10.93 | 0.699±0.443 |
Values are means of replicate cultures±95% confidence intervals (n=6, non-axenic; n= 7, ambient axenic; n=4, elevated axenic). m, realized growth rate over at least two consecutive batch cultures; μ, exponential growth rate of individual cultures; L, lag phase duration; D, die-off proportion.
