Yeast extract was determined to be the ideal co-substrate for methanol incorporation into biomass, providing a statistically significant biomass yield from 0.22 g biomass/ g yeast extract without methanol to 0.28 g biomass/ g yeast extract in the presence of methanol. Experiments were then conducted in continuous culture using varying yeast extract concentrations as a co-substrate with methanol in order to determine optimum growth conditions for methanol consumption. Finally, an adaptive evolution experiment was conducted in an attempt to induce a population of E. coli that showed improved growth on methanol over the genetically engineered base-strain.methanol consumptionescherichia colichemical engineeringThesis
