title: Metabolomic differential display analysis of the white-rot basidiomycete Phanerochaete chrysosporium grown under air and 100% oxygen.
abstract: When the cultural atmosphere of the white-rot basidiomycete, Phanerochaete chrysosporium, was changed from air to 100% oxygen, the lyophilized mycelial weight increased and thickening of extracellular glucan layer was observed in 2-3 days. To better understand the oxygen-stress responsive mechanism of P. chrysosporium, the metabolomic differential display analysis was performed using metabolites isolated from fungal cells grown under either air or 100% O(2) atmosphere. In the GC-MS total ion chromatogram of methanol-extracts from fungal cells, at least 183 peaks were detected and 53 compounds were identified. Among them, veratryl alcohol (VA), threonate, and erythronate were identified as oxygen-stress responsive metabolites. The intracellular concentration of VA increased dramatically within 1 h after an oxygen purge, indicating that VA production is sensitive to the oxygen stress in P. chrysosporium.
