Abstract
As one kind of important secondary metabolites produced by Inonotus baumii, flavones can be applied in food, medicine, and other industries due to their biological activities such as antioxidant, anticancer, and antibacterial activity. To enhance total flavone production in submerged fermentation of I. baumii, three different strategies, optimization of fermentation parameters by statistical designs including Plackett-Burman design and response surface methodology, addition of precursors and elicitors, and two-phase culture, were used. The production of total flavones (PTF) reached 1532.83 mg/L when the optimized medium was used. All precursors and elicitors can increase the PTF. The maximum PTF (2184.06 mg/L, up to 1.57-fold) was obtained with the addition of both AgNO3 and glutathione in fermentation media. Interestingly, when 0.5% (w/v) DM130 macroporous resin as adsorbent was added to fermentation broth on day 4 of culture, the highest production reached 2407.79 mg/L with this two-phase culture strategy. These methods can be further applied to large-scale industrial production and broaden the application of flavones.
