Infrared spectroscopy of phytochrome and model pigments [PDF]

, 1990
Fourier-transform infrared difference spectra between the red-absorbing and far-red-absorbing forms of oat phytochrome have been measured in H2O and 2H2O. The difference spectra are compared with infrared spectra of model compounds, i.e. the (5Z,10Z,15Z)-

Hepatoprotective protein pigment complex phycocyanin from Spirulina maxima and its potential antimicrobial, oxidative stress-modulating effects

The Microbe
In the present study, the antibacterial activity and oxidative stress-modulating effects of phycocyanin extracted from Spirulina maxima were investigated. Phycocyanin was isolated from S. maxima biomass using cold maceration, followed by ammonium sulfate

Application of complexes from phycocyanin and pectin in a model beverage system

Future Foods
The blue-appearing phycocyanin from the cyanobacteria Arthrospira platensis undergoes severe color losses during food production or storage. Thus, many studies have looked at stabilizing phycocyanin against processing conditions such as heat with ...
