The study explored changes in carbon fluxes in the central metabolism of brewer’s yeast in the absence of building blocks such as adenine or nitrogen. These flows provide insight into changes in the central metabolism of brewer’s yeast. It was found that in the absence of a building block, the yeast mainly uses fermentation for growth, producing ethanol. Deletion of Δade1 in purine de novo synthesis reduces ethanol production, and decreased glycerol production in adenine starvation indicates a slowing of central metabolism.
