On the other side, microalgae biomass has been considered as a robust biological solution to fulfill the green energy demand apart from its genuine multi-functionality for carbon dioxide sequestering and wastewater phycoremediation. However, low microalgae productivity is a critical hindrance to be tackled for the successful commercialization of microalgae biodiesel. Hence, the present work investigates the feasibility of agri-food waste such as corncob, banana peels, and onion residues as potential biostimulants for lab-scale cultivation of C. vulgaris. Among all the tested biostimulants, an improved growth performance was attained when C. vulgaris was supplied with biostimulant derived from onion residue, recording biomass concentration of about 1.34 g/L at day 14, which was 81.72 higher than control culture without any biostimulant supplementation. Moreover, despite its outstanding growth-promoting effect, there was no significant drop in the lipid yield of microalgae cultured using onion residue-based biostimulant, demonstrating its effectiveness as a promising low-cost microalgae biostimulant. On the contrary, biostimulant extract prepared from corncob and banana peel retarded the growth of C. vulgaris at the end of the cultivation cycle without any augmentation effects on the biomass or lipid. © 2024 Author(s). date: 2024 publisher: American Institute of Physics official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85188294915&doi=10.1063%2f5.0196834&partnerID=40&md5=89c7e176150ab3b01d3453d712c297a5 id_number: 10.1063/5.0196834 full_text_status: none publication: AIP Conference Proceedings volume: 3041 number: 1 refereed: TRUE issn: 0094243X citation: Uganeeswary, S. and Lam, M.K. and Hemamalini, R. and Lim, J.W. and Pa'Ee, K.F. and Len, K.Y.T. and Tan, I.S. and Show, P.L. and Lee, K.T.
