Abstract:
:Pneumocandin B0 is a hydrophobic secondary metabolite that accumulates in the mycelia of Glarea lozoyensis and inhibits fungal 1,3-β-glucan synthase. Extractive batch fermentation can promote the release of intracellular secondary metabolites into the fermentation broth and is often used in industry. The addition of extractants has been proven as an effective method to attain higher accumulation of hydrophobic secondary metabolites and circumvent troublesome solvent extraction. Various extractants exerted significant but different influences on the biomass and pneumocandin B0 yields. The maximum pneumocandin B0 yield (2528.67 mg/L) and highest extracellular pneumocandin B0 yield (580.33 mg/L) were achieved when 1.0 g/L SDS was added on the 13th day of extractive batch fermentation, corresponding to significant increases of 37.63 and 154% compared with the conventional batch fermentation, respectively. The mechanism behind this phenomenon is partly attributed to the release of intracellular pneumocandin B0 into the fermentation broth and the enhanced biosynthesis of pneumocandin B0 in the mycelia.
