This study delves into an innovative biorefinery approach to extract multiple high-value compounds from a single biomass source, Halobacterium salinarum R1, a resilient halophilic microorganism. By using bio-based solvents, namely an aqueous solution of gamma-valerolactone (GVL) and ethanol, a simple and efficient pipeline approach was developed, recovering unique pigments, including C50 bacterioruberin, as well as two additional fractions consisting of protein and polysaccharides. The process is based on sustainable engineering and green chemistry principles, providing a viable alternative to replacing non-renewable solvents. The study addresses environmental concerns by employing bio-based solvents while presenting a cost-effective and sustainable solution. This approach contributes to developing a high-performance and sustainable alternative, promoting the development of a blue bioeconomy. [ABSTRACT FROM AUTHOR]
