Biopigments, Obtaining and Properties

In this work we report some of the key parameters which determine pigment production in submerged biosynthesis using different nutrient sources like glucose, starch, rice, glutamic acid, with a low oxygen concentration in order to avoid the mycotoxin formation. The chemical composition of biopigment performed by fluorescent X-ray diffraction and atomic emission in coupled inductively plasma indicate a high concentration of C, N, H, and K and the presence of microelements like Co, Cu, Fe, Mn, Zn. The stability of bioproduct determined by electronic spectra in solid state and in different solvents (i.e., water, ethanol, diethyl ether and n-hexane) indicates the instability of bioproduct in the presence of light either in the solid state or in different solvents. Its fresh aqueous solution has strong antioxidant properties, comparable with those of E vitamin.
