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 (0.43 mg/L)
Zn NPs Metal resistance induction Total lipid content increase (0.74 mg/L)
Pb NPs Increase of growth rate Total lipid content increase (0.76 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 12 pg/cell)
Tetraselmis suecica Increase of growth rate Increase of the total lipid (up to 40 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 1.02 g/L at day 18 (subsequently, more total lipid amount is achieved) [166]
