Abstract
Isolating protein from yeast cells by alkaline extraction is enhanced by growing a continuous culture of yeasts at the lowest possible dilution rate (space velocity) where the cell yield is not significantly affected and/or by aging the continuous yeast culture in a second stage of continuous fermentation having a residence time from 2 to 4 hours and a pH of from 4 to 10.
