ABSTRACT: Microalgae can be used as a renewable energy source, as nutritional supplements, and as a source of pharmacological compounds. However, playing in insufficient light conditions usually limits their optimal growth. The research examines the efficacy of red and brown macroalgae-based Seaweed Liquid Fertilizers (SLFs) derived from Hypnea musciformis and Zonaria variegata in stimulating the development of green microalgae. Microalgal cultures were treated with the SLFs to evaluate their effects on growth rate, biomass yield, photosynthetic efficiency, and biochemical composition. The findings indicated that when macroalgae-derived SLF was used, algae grew and exhibited higher biochemical productivity than in the control cultures. The findings demonstrate the opportunities of macroalgae-based SLF as a natural growth factor for the extensive growth of microalgae, with sustainable potential for biofuel production, bioproduct synthesis, and environmentally friendly aquaculture development.
