Microalgae are multifaceted photosynthetic microorganisms with incipient business prospective. Harvesting of microalgae from the medium poses a significant obstacle due to their diminutive size and low concentrations. Thus, from carbon capturing and waste management to biofuels, harvesting of microalgae is in an efficient and environmentally-friendly manner, has become the topic of apprehension. Bioflocculation studies of microalgae Synechococcus, Dunaliella, and Chlorella sp. using Delonix regia leaf protein was undertaken herein. D regia leaf protein had a bioflocculation efficiency of 75%, 76%, and 84% respectively in case of Chlorella sp, Synechococcus sp, Dunaliella sp. As leaf protein is a safe, non-toxic, and environmentally friendly flocculant, it is suitable for effective and ecofriendly microalgal harvesting and has the potential to be upped to an industrial scale.
