Table 4 Improvement of lipid productivity using different types of NPs in some species of microalgae
From: Biomass and lipid induction strategies in microalgae for biofuel production and other applications
Microalgae strain | Type of NPs | Utilization | Lipid profile change | Refs. |
|---|---|---|---|---|
Chlorella vulgaris | Cu NPs | Metal resistance induction | Total lipid increase (up to 32%) | [162] |
Mg NPs | Photosynthesis enhancement | Lipid content increase (0.43Â mg/L) | ||
Zn NPs | Metal resistance induction | Total lipid content increase (0.74Â mg/L) | ||
Pb NPs | Increase of growth rate | Total lipid content increase (0.76Â mg/L) | ||
Isochrysis galbana | Fe NPs | – | No significant difference in total lipid content | [163] |
Pavlova lutheri | Increase of growth rate | Increase of the total lipid (up to 12Â pg/cell) | ||
Tetraselmis suecica | Increase of growth rate | Increase of the total lipid (up to 40Â pg/cell) | ||
Chlorella vulgaris | Nanoscale MgSO4 | Photosynthesis enhancement | 185.29 ± 4.53% improvement in lipid production | [164] |
Chlorella sp. KR-1 | CTAB-decorated Fe3O4 NPs | Improvement of harvesting and cell disruption efficiency | The cells harvested using CTAB-OTES-MNP yielded an approximately 2.3-fold-higher lipid content compared with the control extracted by only hexane | [165] |
Nannochloropsis maritima | Fe3O4 NPs | Improvement of harvesting efficiency | The algal biomass increased up to 1.02Â g/L at day 18 (subsequently, more total lipid amount is achieved) | [166] |
