Cyanobacterial strains that showed high content of phycocyanin, their origin, biomass yield, and phycocyanin purity in a crude extract, based on A615/280 ratio. Percent of C-PC content in biomass was calculated in a crude extract by using spectrophotometric method and it is based on measurements of three separate extractions.
