Conclusion

The study demonstrated mixed algal consortia’s bioremediation potential (removal of nutrients) with the scope for biofuel production. Mixotrophy with self flocculating abilities of algal consortia aided in the effective treatment of wastewater and algal harvest. This technique if replicated in sewage fed ponds and lagoons helps in the decentralised treatment of water with the value added option for energy generation. This would cater to the regional energy demand while mitigating GHGemissions. Thus, bioremediation through mixed algal consortia meets multiple objectives of sustainable development that would help in treatment of wastewater and avert water crisis.
