| Abstract: |
| The crisis of water resources and the worry about environmental pollution promote the upgrading of traditional wastewater treatment process. Microalgae can accumulate lots of high value-added secondary metabolites such as lipids. Microalgae cultivation in wastewater can simultaneously meet the requirements of obtaining microalgae biomass and wastewater treatment. The characteristic of combining microalgae cultivation with wastewater treatment was reviewed, and the role of microalgae-based wastewater treatment processes, including photobioreactors, biofilm-photobioreactors, microalgae-bacterial consortia, microalgae-microbial fuel cells and coupled plant growth regulators, in improving the microalgae biological activity, lipid production capacity and wastewater treatment efficiency were described. In view of the complexity of wastewater composition and the adaptability of microalgae, innovative microalgae-based wastewater processes and technologies are also needed to achieve higher wastewater bioremediation efficiency and yield of high value-added products from microalgae. |
