Microplastics (MPs), as frequent pollutants, persist in aquatic environments and have an impact on the growth biomass production of microalgae. This study employed MPs polyethylene (PE), polystyrene (PS), polypropylene (PP) at concentrations 250 mg/L with MP sizes 50, 100, 300, 500 µm to investigate their influences bio-production Scenedesmus quadricauda. The results revealed that suppressed S. quadricauda increased algal lipid production. order terms inhibitory effect was following: PP > PS PE. size sensitivity 50 100 300 µm. In culture, inhibition microalgal (inhibition rate: 49.26%) accumulation lipids (total content: 65.40%) were most significant, especially neutral content. Additionally, scanning electron microscopy (SEM) Fourier-transform infrared spectroscopy (FTIR) analyses proved rough surface led high aggregation microalgae, reduced intensities protein-, lipid-, carbohydrate-related bands affected structure cells.
