Eutrophication and hypereutrophication in lakes foster harmful blue-green algal blooms, which pose a significant threat to the ecological health of freshwater reservoirs. This study investigated effectiveness bio-flocculation approach using Ganoderma lucidum fungus strain BGF4A1 remove these specifically targeting cyanobacterial species like Microcystis PCC-7914. Key flocculation parameters, concentrations, adsorption kinetics, pellet morphology were explored this research. Our results demonstrate that G. can effectively up 93.70 % cyanobacteria (measured as chlorophyll-a absorbance), 75.28 chemical oxygen demand (COD), 92.09 total suspended solids (TSS) under optimal conditions: an initial pH 4, 1 fungal volume (w/v), 48 h contact time, 100 rpm agitation at room temperature. Microscopic examination water samples before after treatment confirmed reduction colonies, indicating death or decline targeted organisms. Morphological analysis field emission scanning electron microscopy (FESEM) revealed cells deposited on hyphae pellets, contrast smooth surface control pellets. These novel culture technologies show great promise bio-flocculating agents for removing algae potentially be adapted microalgae harvesting biodiesel production.
