Table 2. The regressions of the Logistic model on K. mikimotoi population growth when exposed to N starvation conditions.
| Population growth parameters | Growth equation | Carrying capacity K (×104 cells mL-1) | r (d-1) | Tp (d) | R2 |
|---|---|---|---|---|---|

| N:P = 1:1 | N = 31.36/(1+e(3.623–0.577t)) | 31.36* | 0.578 | 6.2 | 0.975 |
| N:P = 2:1 | N = 33.89/(1+e(3.577–0.515t)) | 33.89* | 0.515 | 6.9 | 0.961 |
| N:P = 4:1 | N = 37.33/(1+e(3.533–0.498t)) | 37.33* | 0.498 | 7.0 | 0.975 |
| N:P = 8:1 | N = 47.05/(1+e3.263–0.444t)) | 47.05* | 0.444 | 7.3 | 0.985 |
