Volatiles of Shiraia fruiting body-associated Pseudomonas putida No.24 stimulate fungal hypocrellin production.

ABSTRACT: Hypocrellins are major bioactive perylenequinones from Shiraia fruiting bodies and have been developed as efficient photosensitizers for photodynamic therapy. Pseudomonas is the second dominant genus inside Shiraia fruiting bodies, but with less known actions on the host fungus. In this work, the effects of bacterial volatiles from the Shiraia-associated Pseudomonas on fungal hypocrellin production were investigated. Pseudomonas putida No.24 was the most active to promote significantly accumulation of Shiraia perylenequinones including hypocrellin A (HA), HC, elsinochrome A (EA) and EC. Headspace analysis of the emitted volatiles revealed dimethyl disulfide as one of active compounds to promote fungal hypocrellin production. The bacte
