Extraction of phycocyanin-A natural blue colorant from dried spirulina biomass: Influence of processing parameters and extraction techniques.

Journal of Food Science, 2020
Phycocyanin, a natural blue colorant, is typically extracted from liquid biomass of Arthrospira platensis, a blue-green algae called spirulina. In this study, we developed a scalable process to extract phycocyanin from dried spirulina biomass.

Coloring with three‐colored subgraphs

Journal of Graph Theory, 2003
AbstractLet f(n) be the minimum number of colors required to color the edges of Kn,n such that every copy of K3,3 receives at least three colors on its edges. We prove that $$(0.62+o(1))\sqrt{n}< \, f(n)< \, (1+o(1))\sqrt{n}$$, where the upper bound is obtained by an explicit edge‐coloring.
