Phycobiliproteins have been used as a natural dye, an analytical probe for fluorescence studies, and chemical medicinal use. An ultrafiltration membrane is useful the purification of phycobiliproteins. This study addressed phycobiliprotein-containing solution, extracted from Nostoc commune , which was individually performed by two kinds (MWCO 150 kDa 10 kDa) in cross-flow. Three proteins were m...

Two-photon-induced fluorescence is observed from the photodynamic phycobiliprotein phycoerythrin. Temporal, spectral, and intensity-dependent properties of the two-photon-induced fluorescence emission from phycoerythrin excited by a 1.06-mum laser beam are reported. The measured two-photon absorption cross section of phycoerythrin is an order of magnitude larger than that of Rhodamine 6G. The p...

The present study evaluated the effect of multiple variables (drying time, drying temperature, biomass/solvent ratio, glass beads/biomass extraction and speed) in solubilization three different phycobiliproteins (C-PC, APC, PE) from a thermotolerant Oscillatoria sp. strain was grown BG11 media (28 °C, light: dark cycle 12:12 h at 100 µmol·m−2·s−1, 20 days) experiments were conducted according t...

Photosynthetic phycobiliprotein complexes from Spirulina maxima were purified and fractioned by gel chromatography. A mathematical model was developed for the fractionated to successfully represent fluorescence decay rate under exposure excitation light. Each complex had a different ratio of phycobiliproteins, such as allophycocyanin, phycocyanin, or phycoerythrin, but their trends determined s...

The relatedness of several marine Synechococcus spp. was estimated by DNA hybridization. Strains isolated from various geographical locations and representing a diversity of DNA base compositions and phycobiliprotein profiles were compared by restriction fragment length polymorphisms for a number of genes. DNAs from two marine red algae and a cryptomonad alga (which exhibit a phycobiliprotein c...

Wild type Gracilaria tikvahiae, a macrophytic red alga, and fourteen genetically characterized pigment mutants were analyzed for their biliprotein and chlorophyll contents. The same three biliproteins, phycoerythrin, phycocyanin, and allophycocyanin, which are found in the wild type are found in all the Mendelian and non-Mendelian mutants examined. Some mutants overproduce R-phycoerythrin while...
