Global increase in demand for production of biofuels, coupled with potential efficacy of microalgae, has largely been the driving force for progression in microalgae-based research. Apart from their utilization in renewable energy, these photosynthetic organisms have several other high-value applications (e.g in biopharmaceutical and nutraceutical industries). However, large-scale cultivation of microalgal biomass and manufacture of microalgal products, require cost-effective technologies. Microalgae have a low sedimentation velocity; moreover, their colloidal characteristic, together with the negative charge on the surface, makes harvesting difficult. Harvesting of microalgal biomass poses as a major bottleneck as it generally accounts for about 20 to 30% of the total cost of cultivation. Amidst a range of harvesting techniques adopted (coagulation, flocculation, and centrifugation), bio-flocculation has emerged as a cost-effective, non-perilous, commercially suitable method for microalgal harvesting.
