Fermentation measurements for ∆gapN (o) and wild type (•) C. saccharoperbutylacetonicum N1‐4(HMT). Cultures were grown on 40 g l⁻¹ glucose in YETM media in bespoke bioreactors (Monaghan et al., 2021); 0.1 M MES was supplemented as a pH buffering agent and the following parameters were monitored: (A) OD₆₀₀; (B) pH; (C) redox potential of media (mV vs. NHE); (D) Glucose concentrations in growth media. Data points are mean values of a total of six repeats including three biological repeats. Error bars represent the standard deviation of mean.
