Volumetric activity (green diamond) and biomass yields (dry cell weight per litre) (black circle) during bioreactor cultivations of each target protein. Arrows indicate the initiation of the glycerol fed-batch phase (20–22 h), where a 50% (w.v−1) glycerol feed supplemented with trace salts was added at a rate of 72.6 mL/h. a Glucuronoyl esterase (GE) b Cellobiose Dehydrogenase (CDH). Error bars indicate standard deviation from mean of three fermentation replicates. c SDS-PAGE analysis of final fermentation samples (each lane representing one replicate of a bioreactor fermentation) of 20 μL supernatant containing the target proteins. Lane 1: Protein molecular weight marker. Lane 2–4: CDH-containing supernatant (rCDH, 127 KDa). Lanes 5–7: Glucuronoyl esterase-containing supernatant (rGE, 78 KDa)
