Overall physiological assessment of four potential host strains for biotechnology applications: V. natriegens, E. coli (evolved and wild-type), and the thermophilic Geobacillus LC300. The values reflect growth at 37 °C for the mesophilic strains, and at 72 °C for Geobacillus LC300. The growth rates (A), and biomass specific glucose (B) and oxygen (C) uptake rates are shown. The results for E. coli and Geobacillus LC300 were taken from previous reported studies (Crown et al., 2015; Cordova et al., 2016).
