Production of Naphthoquinone Mycotoxins and Taxonomy of Penicillium viridicatum

A Ciegler et al. Appl Environ Microbiol. 1981 Sep.

Abstract

Groups I and II of Penicillium viridicatum were further differentiated on the basis of synthesis of two mycotoxins, xanthomegnin and viomellein. Strains previously classified as group II produced these pigments, whereas those in group I did not. These napthoquinone pigments were quantitated by thin-layer chromatography and high-pressure liquid chromatography. A new mobile phase of toluene and acetic acid effected a baseline separation of the two components. It is proposed that such biochemical distinctions be incorporated into an artificial taxonomic scheme of use to nontaxonomists.
