Fig. 5From: Spatial monitoring of hydrolysis in a plug-flow bioreactor: a support for flexible operation?Feedstock-related dependance of the specific hydrolysis yield (SHY) on the pH-value at the inlet (A) and outlet (B) port for PFR1 (filled symbols) and PFR2 (open symbols). Measurements during start-up (W1–5) and the first 2 weeks with 7 d of HRT in PFR1 (weeks 9, 10) were excludedBack to article page
