Aeration effect on SPB1 biosurfactants production into 2,6 L fermentor using the formulated medium.
| Aeration profile (%) | Biosurfactants (mg/L) | CFU (108 cells/mL) | *Relative biosurfactants yield (mg/1010cells) |
|---|---|---|---|
| 10 | 2410.160 ± 23 | 15.30 ± 2 | 15.75 |
| 20 | 3801.120 ± 34 | 16.60 ± 3 | 22.89 |
| 30 | 4922.540 ± 25 | 20.00 ± 1 | 24.61 |
| 40 | 4230.423 ± 13 | 27.50 ± 3 | 15.38 |
| 60 | 2609.140 ± 11 | 36.00 ± 1 | 7.24 |
*Relative biosurfactant yield was calculated as the ratio of biosurfactant (mg/L) over CFU (1010 CFU/L), both of them were determined at the end of fermentation.
