A mixture of Kluyveromyces fragilis biomass and coagulated whey proteins was obtained by fermentation of whole whey. This product had a chemical composition similar to that of washed products reported in the literature with high-crude protein and low-ash contents. The product had a high content of sulphur-containing amino acids and tryptophan, which are usually limiting in yeast biomass. Lysine content was inexplicably lower than the expected value, being the limiting amino acid in this case. The chemical score of the protein was 91%. From the biomass-whey proteins product a protein isolate could be recovered with a yield of 80%. The protein content of the isolate was 75%, and the nucleic acids were reduced by 90.8%. The cell-wall debris were also considerably reduced.
