Table 1. Cell physiology of all strains in batch and chemostat cultivations.

All values are average±s.e.m. from at least three biological replicates. μmax, maximum specific growth rate on glucose in batch cultures; YSX, biomass yield on glucose in chemostat cultures; YSAc, acetate yield on glucose in chemostat cultures. μmax for each strain was determined based on the CO2 emission during the batch phase of the culture. | ||||
