MENDEZ-ZAVALA, A et al. Fungal production of the red pigment using a xerophilic strain Penicillium purpurogenum GH-2. Rev. Mex. Ing. Quím [online]. 2007, vol.6, n.3, pp.267-273. ISSN 1665-2738.

In this study, the capacity of Penicillium purpurogenum GH2 for pigments production was evaluated in liquid and solid state fermentation, as well using minimum and enriched media. The strain was able to growth and produce pigments in these media. Nine culture media reported for pigment production were evaluated in solid state fermentation. Microorganism was able to of growth in all media tested, obtaining different specific growth rates, the highest specific growth rate was reported in the 1, 3 and 9 media (0.0903, 0.0874, y 0.0837 cm. h-1, respectively). The pigments production, was observed in 6 of the 9 analyzed media. In accordance with the exploration scanning analysis, the values of maximum absorbances were found between 400 and 600 nm; in this regions two peaks at 505 and 425 nm were used to evaluated the pigment concentration.
