As food safety continues to gain prominence, phycocyanin (PC) is increasingly favored by consumers as a natural blue pigment, which is extracted from microalgae and serves the dual function of promoting health and providing coloration. Spirulina-derived PC demonstrates exceptional stability within temperature ranges below 45 °C and under pH conditions ...

Fluorescence properties of Phycocyanin and Phycocyanin-human serum albumin complex
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2020In this work, the fluorescence properties of Phycocyanin (PC) and the corresponding quenching effects are investigated in attendance of human serum albumin (HSA). At first, PC is excited at 532 nm using CW SHG Nd:YAG laser, then the emission wavelength, Stokes shift, quantum yield, extinction constant and self-quenching coefficient are obtained based ...

Biosynthesis of phycocyanin in vivo
Biochimica et Biophysica Acta (BBA) - General Subjects, 1970Abstract 1. 1. Cells of the unicellular alga, Cyanidium caldarium , synthesize phycocyanin in the light but lack this pigment when grown in darkness. Dark-grown cells fed δ-amino[4- 14 C]levulinic acid and [4,5- 3 H 2 ]leucine synthesized double-labeled phycocyanine in the light.

C-Phycocyanin: Minimum Molecular Weight
Science, 1964Sedimentation and immunodiffusion experiments indicate that the molecular weight for the minimum molecular unit of C-phycocyanin is 30,000. This result agrees with an analysis of available data on amino acid content for C-phycocyanins from several different algae.

Photooxidative reactions of c-phycocyanin
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972Abstract 1. Aging cultures of blue-green algae, as well as cultures kept under certain adverse physiological conditions, often show bleaching of photosynthetic pigments. 2. Crude extracts containing c -phycocyanin of the blue-green algae, Plectonema boryanum or Anacystis nidulans , bleach when exposed to short wavelengths of visible light ...

Purification and bioactivities of phycocyanin
Critical Reviews in Food Science and Nutrition, 2016Phycocyanin is an important light-harvesting pigment antenna protein in cyanobacteria, rhodophyta, cryptophyta, and glaucophyta, with a variety of bioactivities. The introduction of purification and bioactivities of phycocyanin contributes to a significant improvement in developing it into final processed products. In fact, the knowledge of phycocyanin

A comparison of cryptophytan phycocyanins
Archives of Microbiology, 1975The spectroscopically different phycocyanins present in the type strain of Hemiselmis virescens, Millport 64, and in a second strain of this cryptophytan species, Plymouth 157, have been purified and compared. They are similar in native molecular weight and in subunit structure, both containing alpha and beta subunits with molecular weights of ...

Characterization of cryptomonad phycoerythrin and phycocyanin
Archives of Biochemistry and Biophysics, 1976Phycoerythrin, a chromoprotein, from the cryptomonad alga Rhodomonas lens is composed of two pairs of nonidentical polypeptides (..cap alpha../sub 2/..beta../sub 2/). This structure is indicated by a molecular weight of 54,300, calculated from osmotic pressure measurements and by sodium dodecyl sulfate (SDS) gel electrophoresis, which showed bands with
