Effect of iron and magnesium addition on population dynamics and high value product of microalgae grown in anaerobic liquid digestate.

ABSTRACT: In this study, FeSO₄ supplementation ranging from 0 to 4.5 mM, and MgSO₄ supplementation ranging from 0 to 5.1 mM were investigated to observe the effect on the population dynamics, biochemical composition and fatty acid content of mixed microalgae grown in Anaerobic Liquid Digestate (ALD). Overall, 3.1 mM FeSO₄ addition into ALD increased the total protein content 60% and led to highest biomass (1.56 g L^-1) and chlorophyll-a amount (18.7 mg L^-1) produced. Meanwhile, 0.4 mM MgSO₄ addition increased the total carotenoid amount 2.2 folds and slightly increased the biomass amount. According to the microbial community analysis, Diphylleia rotans, Synechocystis PCC-6803 and Chlorella sorokiniana were identified as mostly detected
