Fig. 5From: Development of a Pichia pastoris cell factory for efficient production of germacrene A: a precursor of β-elemeneFed-batch fermentation of GAS16 for high-level production of germacrene A. Fed-batch fermentation was performed in a 1-L bioreactor. Samples were taken every 8 h to analyze the concentration of glucose, ethanol, and germacrene A as well as cell densitiesBack to article page
