Bioprocesses for SLs fermentation
| Fermentation mode | Glucose (g l−1) | Oleic acid (g l−1) | Period (h) | Sophorolipids (g l−1)a | Biomass (g l−1) | Productivity (g l−1 h−1) | Product purity |
|---|---|---|---|---|---|---|---|
| Batch fermentation in conventional bioreactor | 90 | 90 | 96 | 104.7 | 21.98 | 1.09 | – |
| Fed‐batch fermentation in conventional bioreactor | 120 | 120 | 96 | 120 | 24.02 | 1.25 | – |
| Semicontinuous fermentation in new bioreactor with DVDSB | 420 | 385 | 320 | 484 | 61.76 | 1.51 | 60% |
| Semicontinuous fermentation in DVDSB coupled with two‐stage separation system | 510 | 380 | 300 | 477 | 67.96 | 1.59 | 74% |
a. The production of sophorolipids was calculated by gross product/the final volume of fermentation broth.
