Abstract
Process for reducing nucleic acid content of yeasts and bacteria comprising heat shocking for a period of time and at a temperature selected to increase effectiveness of enzymes which break down nucleic acids without allowing proteins to break down or leak out of the cell, and incubating the heat-shocked cells at a temperature lower than the heat shock temperature under conditions in which the cells remain intact and nucleic acid fragments permeate the cell walls.
