摘要： Economically efficient biomass production is crucial to lift the microalgal circular bioeconomy requiring low production cost with higher biomass and value-added products. In this study, Micractinium sp. YACCYB505 was cultured at different illuminations (1600, 2400, 3200 lux) and CO2 conditions (up to 10%) to evaluate biomass productivity and accumulation of macromolecules (lipid, carbohydrate and protein). The product optimization study was conducted to analyze individual variables of environmental factors by using a Box-Behnken design. Highlight intensity (3200 lux) and 5% CO2 aeration maximized biomass productivity on 11th day of microalgal harvest. Microalgal lipid accumulation indicated positive impact on increased CO2 aeration and light intensity treatment. Similarly, a considerable amount of protein content (9%) was increased at higher CO2 aeration but raised light intensity had a negative impact on protein biosynthesis. Significant carbohydrate content reduction was observed with increased light intensity and CO2 aeration. The overall results proved that increased CO2 concentration (10%) and light intensity (3200 lux) enhanced lipid accumulation (32%) and biomass productivity in Micractinium sp., which provides potential to achieve a sustainable, cost-effective biomass and value-added products.
