Microalgae cultivation in wastewater is a promising strategy for reducing nutrient loads and generating biomass that can be further exploited. Although microalgae grown under such conditions are not suitable high-value applications, the resulting still valuable uses as biofuels, biofertilizers, or animal feed. In this study, Chlorella sorokiniana was cultivated dairy and, to best of our knowledge, first time spent effluent from gas fermentation, assess its potential sustainable growth medium. Growth kinetics productivity were evaluated at different dilution ratios, it found high concentrations ammonium hexanol undiluted effluents inhibitory, while an optimized 50:50 led highest accumulation (1.96 g L−1) (0.5 L−1 d−1) C. sorokiniana. This significantly reduced nitrogen (100%), phosphate sulfate (68%), carbon (61%) contents, demonstrating effective bioremediation activity. Furthermore, fatty acid profile revealed increased polyunsaturated fraction, enhancing feed supplement. Overall, contributing circular bioeconomy, approach scalable cost-effective, freshwater chemical dependency production.
