Bioreactor data. Batch bioreactor cultivations in triplicate. The three production strains were cultured in triplicate for the parental strain (Parental), intracellular production strain (ZERA-GLA) and secretion strain (CBHI-GLA) and then analysed by transcriptional profiling for physiological observations. (A) Cell dry weight determined over time in grams of dried biomass per litre of culture volume. (B) Carbon dioxide monitoring was determined over time and measured in percent dissolved CO2.
