Fig. 4From: Metabolic engineering of Ashbya gossypii for deciphering the de novo biosynthesis of γ-lactonesImproved biosynthesis of γ-lactones by engineered A. gossypii strains. a Volumetric (μg/L) and b specific (μg/gCDW) production of total γ-lactones. Data are presented as mean ± standard deviation of three biological replicates. Cultures were carried out in AFM for 72 h. Asterisks represent significant differences to the control (ATCC). **(p < 0.01), ***(p < 0.001) and ****(p < 0.0001)Back to article page
