| Agitation speed (rpm) | C0 (g/L) | Cend (g/L) | Total carbon consumption (g/L) | Alk0 (mL) | Alkend (mL) | Total alkali consumption (mL) | Lac0 (g/L) | Lacend (g/L) | Total lactate accumulation (g/L) |
| 100 (control) | 60.00 | 10.20 | 49.80 | 1,200 | 200 | 1,000 | 0.00 | 10.72 | 10.72 |
| 150 | 9.40 | 50.60 | 500 | 700 | 10.08 | 10.08 |
| 200 | 12.68 | 47.32 | 100 | 1,100 | 9.88 | 9.88 |
