Characterization of the cultivation of Paenibacillus polymyxa in reduced Moppa medium in a fermenter. Reduced Moppa medium (specified in Table 2). a Oxygen transfer rate (OTR), b Optical density (OD) and pH, c Maltose, glucose and citrate concentration, d Lactate concentration. Measuring points in brackets are considered outliers. For clarity, only every 720th measuring point is marked as a symbol for OTR. Cultivation conditions: temperature 33 °C, filling volume 1 L, pH control at pH 6.5 with NH3 • aq and H3PO4 solutions, without MES buffer. The cultivation in the fermenter is also shown in Fig. 6
