Semi-continuous fermentation of P4R5 with CCR-derived sugar as the carbon source. a, c Schematic representation of the semi-continuous fermentation of P4R5 for PEFA production in flasks and fermenter. b Three-round fermentation in 250-mL flasks. Each round of fermentation lasted for 5 days. The PEFA titer, PEFA productivity, and pH during fermentation were determined at the end of each round. abcData with different superscripts differ (p < 0.05). d Two-round fermentation in a 10-L fermenter. Each round of fermentation lasted for 5 days. The time course of PEFA titer, biomass, SCO content, residual reducing sugar, and pH during fermentation were determined. The concentration of glucose and xylose were also determined by HPLC analysis (Additional file 2: Fig S2b). The arrows indicate the time points for product collection and carbon source supplementation. Three replicates were prepared for statistical analysis
