摘要： This research aimed to use a novel and effective ultrasound (US) approach for obtaining high bio-compound production, hence proposing strategies for boosting active ingredient biosynthesis. Furthermore, the US promotes several physiological effects on the relevant organelles in the cell, morphological effects on the structure of Phellinus igniarius mycelium, and increases the transfer of nutrients and metabolites. One suitable US condition for flavonoid fermentation was determined as once per day for 7-9 days at a frequency 22 + 40 kHz, power density 120 W/L, treated 10 min, treatment off time 7 s. The flavonoid content and production increased about 47.51% and 101.81%, respectively, compared with the untreated fermentation (P < 0.05). SEM showed that sonication changes the morphology and structure of Ph. igniarius mycelium; TEM reveals the ultrasonic treatment causes organelle aggregation. The ultrasound could affect the metabolism of the biosynthesis of the active ingredients.
