Exploring the lichenization continuum through the marine tripartite symbiosis of Collemopsidium pelvetiae

American Journal of Botany, Volume 113, Issue 6, June 2026.
Abstract Premise Symbioses between lichen‐forming fungi and brown algae (phaeophytes) are extremely rare. We investigated the interactions between the marine fungus Collemopsidium pelvetiae and its two photosynthetic partners, the brown alga Pelvetia canaliculata and a cyanobacterial symbiont to address questions on symbiosis biology, lichenization ...

Single-molecule spectroscopy selectively probes donor and acceptor chromophores in the phycobiliprotein allophycocyanin [PDF]

, 2004
We report on single-molecule fluorescence measurements performed on the phycobiliprotein allophycocyanin (APC). Our data support the presence of a unidirectional Forster-type energy transfer process involving spectrally different chromophores, alpha84 ...

Pilot-Scale Phycocyanin Extraction by the Green Two-Step Ultrasound-Based UltraBlu Process

Separations
Phycocyanin is a natural, non-toxic, blue pigment-protein with many commercial applications. Its exploitation in various biotechnological sectors strongly depends on its purity grade (P).

Studies on phycobiliproteins in Algae. VI. Light-harvesting phycobiliprotein pigments in some Rhodophyta from the Adriatic Sea

Acta Societatis Botanicorum Poloniae, 2014
The phycobiliprotein content in 5 species of red algae from the coast of the Adriatic Sea' was studied by chromatography on Sephadex G-100. The phycobiliproteins, R-phycoerythrin, C-phycocyanin and allophycocyanin were identified.
