Open AccessEffects of branched-chain amino acids on Shiraia perylenequinone production in mycelium cultures
Perylenequinones from Shiraia fruiting bodies are excellent photosensitizers and widely used for anti-cancer photodynamic therapy (PDT). The lower yield of Shiraia perylenequinones becomes a significant bottlenec...

Open AccessContrasting regulation of live Bacillus cereus No.1 and its volatiles on Shiraia perylenequinone production
Fungal perylenequinones (PQs) are a class of photoactivated polyketide mycotoxins produced by plant-associated fungi. Hypocrellins, the effective anticancer photodynamic therapy (PDT) agents are main bioactive...

Transcriptomic responses involved in enhanced production of hypocrellin A by addition of Triton X-100 in submerged cultures of Shiraia bambusicola
The addition of surfactant is a useful strategy to enhance the product yield in submerged fermentation process. In this study, we sought to explore the mechanism for the elicitation of Triton X-100 on producti...
