Table 3 Average values of key production parameters obtained from the exponential methanol feed phase of fed-batch cultivations using a pre-programmed µ of 0.03 h-1. Volumetric productivity (QP), biomass yield on methanol (YX/S), 3-HP yield on methanol (YP/S), 3-HP yield on biomass (YP/X), CO2 yield on methanol (YCO2/S), specific substrate consumption rate (qS), specific 3-HP production rate (qP), specific carbon dioxide evolution rate (qCO2), and experimentally measured mean specific growth rate (µ). Cultivations were performed in duplicate and biomass concentration analyses were performed in triplicate. ± indicates SD of the biological replicates
