Process for the production of yeast biomass

摘要

The present invention describes a process for the production of yeast biomass on a commercial scale by culturing yeast cells under aerobic conditions in a growth medium which comprises at least one assimilable carbon source and recovering the yeast cells to obtain yeast biomass, characterised in that the yeast cells functionally overexpress a transcriptional activator such, that the yeast cells have an increased respiratory capacity and an increased fermentative capacity in comparison with the yeast cells not overexpressing the transcriptional activator. The invention also describes the use of yeast biomass according to the invention in the preparation of a food product.
