Batch fermentation with production strain Top10.4. The production profiles for cell dry weight (CDW), naringenin and p-coumaric acid, and the substrate usage of glycerol is shown. Also, growth rate (µ), yield (YPX) of product (naringenin, P) on biomass (CDW, X) and the specific production rate (qp) for naringenin are given for the time frame indicated between dashed vertical lines, encompassing the production process up to the transition to the stationary growth phase. (Error bars = product extraction technical error, n = 2)
