Amino Acid Composition of the Protein from a Mushroom (Pleurotus sp.).

Approximate analyses of mushroom protein (Pleurotus sp.) revealed that it contains 2.78% protein and 0.14% nonprotein nitrogen on a fresh-weight basis. A total of 17 amino acids, including all the essential amino acids, were qualitatively identified. Quantitative estimation of essential amino acids showed that, except for methionine and phenylalanine, all are in fairly high concentration. From these studies, it was concluded that the supplementation of this mushroom with cereal diet would help to overcome lysine deficiency.
