Inside out <i>Porphyridium cruentum</i>: Beyond the Conventional Biorefinery Concept
Here, an unprecedented
biorefinery approach has been designed to
recover high-added value bioproducts starting from the culture ofPorphyridium cruentum. 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 ofP. cruentumculture was set up
