Inside out Porphyridium cruentum : Beyond the Conventional Biorefinery Concept. Acs Sustain Chem Eng, 11:381-389, 2023 Cited by PubMed Abstract: Here, an unprecedented biorefinery approach has been designed to recover high-added value bioproducts starting from the culture of. This unicellular marine red alga can secrete and accumulate high-value compounds that can find applications in a wide variety of industrial fields. 300 ± 67 mg/L of exopolysaccharides were obtained from cell culture medium; phycoerythrin was efficiently extracted (40% of total extract) and isolated by single chromatography, with a purity grade that allowed the crystal structure determination at 1.60 Å; a twofold increase in β-carotene yield was obtained from the residual biomass; the final residual biomass was found to be enriched in saturated fatty acids. Thus, for the first time, a complete exploitation ofculture was set up. PubMed: 36643001DOI: 10.1021/acssuschemeng.2c05869 PDB entries with the same primary citation |
