Extraction of Bio-pigments from the Green Microalgae Chlorella pyrenoidosa Under Different Solvent Ratios

Abstract Nowadays, the use of microalgae biomass is evolving rapidly for their various applications such as food, pharmaceutical, and cosmetics. One essential compounds in that have good perspectives market pigment since it can be used a natural colorant food or However, extraction bio-pigments from green Chlorella pyrenoidosa under different solvent ratios still rarely reported. Therefore, this study aims to investigate bio-pigment potential C. extracted ethanol ratios. The algae-to-ethanol 1:5, 1:7.5, 1:10 were employed study. Overall, contains total chlorophyll content much higher than carotenoids due fact autotrophic microorganism performs photosynthesis. decreased with an increase ratio, i.e., 134.47, 133.74, 129.46 μg/mL at ratio 1:10, respectively. In contrast, carotenoid slightly increased 86.64, 87.08, 88.45 main extract molar 1:5 identified c (47.09 μg/mL), followed by b (38.50 (28.67 d (20.23 μg/mL).
