| Abstract: |
| The low yield of microalgae metabolites restricts the industrialization development of microalgae.Recently, coupling of antioxidant and abiotic stress is an efficient method to cope with the low yield of metabolites by microalgae. In order to provide new ideas for the efficient synthesis of lipid and carotenoid by microalgae under abiotic stress conditions, the research progress on the effects of combined antioxidant and abiotic stresses in regulating lipid and carotenoid synthesis by microalgae were reviewed, and the mechanism of action of antioxidants in regulating the synthesis of secondary metabolites and resistance of algal cells was further analyzed. It can be concluded that antioxidants could maintain the growth of microalgae, promote the accumulation of metabolites, and alleviate oxidative damage by regulating intracellular redox balance, signal transduction and the transcription level of related genes. |
