TABLE 1.
Specific energy consumptions (EC, in kWh/kgDW) of the different cell disruption techniques for the recovery of a unit mass of target compounds (WSP, water-soluble proteins; C-PC, C-phycocyanin; CHO, carbohydrates) from A. platensis microalgae suspensions.
| Disruption method |
Specific energy consumption (kWh/kgDW) |
||
| WSP | C-PC | CH | |
| PEF M (TIN = 25°C) | 8.1 | 65.7 | 13.7 |
| PEF B (TIN = 25°C) | 10.8 | 120.1 | 15.9 |
| Mild heating (TIN = 35°C) | 79.6 | 401.3 | 443.9 |
| Mild heating (TIN = 35°C) + PEF M | 8.4 | 47.9 | 17.1 |
| Mild heating (TIN = 35°C) + PEF B | 12.1 | 100.1 | 20.1 |
| HPH | 10.5 | 110.5 | 53.7 |
PEF M and PEF B indicate the PEF treatment (20 kV/cm, 100 kJ/kg) with mono and bipolar pulses (delay time = 10 μs), respectively. HPH treatment conditions: P = 150 MPa; nP = 3.
