Design of experiments‐driven optimization of Porphyridium marinum cultivation: impact of operational variables on phycoerythrin and exopolysaccharide production

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Among the Porphyridium genus, Porphyridium marinum exhibits the highest phycoerythrin (PE) content. In this study, the metabolic trade‐off between biomass, PE, and sulfated exopolysaccharide (EPS) production was assessed under varying nitrogen and sulfur availability, light intensity, residence time, and cultivation mode.

A New Exopolysaccharide of Marine Coral-Associated Aspergillus pseudoglaucus SCAU265: Structural Characterization and Immunomodulatory Activity

open access: yesJournal of Fungi, 2023
Recent studies have found that many marine microbial polysaccharides exhibit distinct immune activity. However, there is a relative scarcity of research on the immunomodulatory activity of marine fungal exopolysaccharides.

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...
