Algae biorefinery is gaining much attention for the sustainable production of value-added products (e.g., biofuels, protein supplements etc.) globally. The current study aimed to investigate the relationship between lipid production and bacteria growth by an initial microalgae Chlorella vulgaris density culture in seafood wastewater effluent (SWE). According to our results, the initial C. vulgaris concentration in SWE influenced lipid accumulation. The concentration ranged from 25-35 mgL(-1) which corresponds to SWE's chemical oxygen demand concentration of 365.67 +/- 3.45 mgL(-1). A higher microalgae growth rate and lipid content of 32.15 +/- 1.45% was successfully attained. A higher lipid content, approximately double, was observed when compared to the control (16.8 +/- 0.5%). Moreover, this study demonstrates that bacteria inhibited microalgae growth as the initial cell density stepped over 35 mgL(-1), which also affected lipid accumulation. This study shows an optimal lipid accumulation attained at moderate Chlorella vulgaris density culture in SWE. Hence, wastewater treatment incorporating microalgae culture could be greatly developed in the future to achieve a greener environment.
