| Abstract: | Fungal pigments are a potential resource as natural food colorant. Endophytic fungus SX01, which is able to produce abundant
soluble red pigments, was isolated from the twigs of Ginkgo biloba L. For further research and utilization of this strain and its secondary metabolites, morphological and molecular characteristics
of SX01 was identified. Morphological identification which employed light microscope and scanning electron microscope showed
that SX01 was a species of genera Penicillium. ITS1-5.8S-ITS2 region and 18S rRNA gene were then cloned, and the molecular phylogeny of these two sequences proved that
strain SX01 was Penicillium purpurogenum. |
