Figure 4: Influence of PHB accumulation on the productive growth kinetics by taking into account A: µmax = 0.0146 h-1 and B: µmax = 0.05 h-1. For calculating the specific growth rate according to equations 15 and 18, YmaxactBM = 0.789 g active biomass (g MTBE)-1, mS = 0.21 mmol MTBE g-1 h-1 and KS = 1 mM were used.
