The principle of parabolic feed for a fed-batch culture of baker's yeast.
A parabolic nutrient supplementation has been derived by the specific growth rate, sugar conversion rate, and Pasteur effect, followed by high qualitative and quantitative biomass production with the lowest sugar consumption. The method produced about 95% cells in the G1 phase that were more resistant to drying and aging. These features are particularly important in the process of making dry yeast. It appears that the parabolic feed method may be used to species culture that show the Pasteur effect or produce byproducts from sugar. This may be because the supplementation is in conformity with reproducible kinetic growth during the fed-batch culture.
