摘　　要：Microalgae are cultured commercially as healthy food, cosmetic products, food preservatives, and a source of valuable compounds. However, the high cost of commercial culture medium is one of the challenges to microalgal production. Therefore, it is essential to find an alternative cost-effective culture medium. Aquaculture wastewater is considered as a highly potential candidate due to its high nutrient content and large quantity generated from the rapid growth of aquaculture sector. In this study, Tetraselmis chuii cultured in different media with or without wastewater was evaluated for its growth, proximate composition and carotenoid production. The results showed that significantly(P < 0.05) higher growth(4.3 × 105 cells mL^(-1)) and protein(56.4% dry weight), lipid(44% dry weight) and carbohydrate(20% of dry weight) contents were found in T. chuii when they were cultured in the combination of both wastewater and Conway(wastewater + Conway) medium. However, carotenoid production of T. chuii was significantly increased(P < 0.05) when it was cultured in wastewater only, followed by Conway + wastewater and Conway medium only. Therefore, the incorporation of wastewater with commercial medium Convey is recommended for a cost-effective microalgae culture, as well as for the enhancement of growth and nutritional content of microalgae.Microalgae are cultured commercially as healthy food, cosmetic products, food preservatives, and a source of valuable compounds.

The results showed that significantly （P 〈 0.05） higher growth （4.3 × 105 cells mL？1） and protein （56.4% dry weight）, lipid （44% dry weight） and carbohydrate （20% of dry weight） contents were found in T. chuii when they were cultured in the combination of both wastewater and Conway （wastewater ＋ Conway） medium. However, carotenoid production of T. chuii was significantly in-creased （P 〈 0.05） when it was cultured in wastewater only, followed by Conway ＋ wastewater and Conway medium only. Therefore, the incorporation of wastewater with commercial medium Convey is recommended for a cost-effective microalgae culture, as well as for the enhancement of growth and nutritional content of microalgae.
