Abstract：Through the determination of amino acid content in sporocarps,the parent Agaricus bisporus strain FA15 and its mutant strains FA15-5 and FA15-6 were comprehensively assessmented in protein nutritive values using the non-biological indicants with the egg protein as standard protein and the essential amino acid reference pattern of WHO/FAO as evaluation criterion.The results showed that the kinds of amino acids in the parent and the two mutant strains were complete,and their essential amino acids accounted for 36.99%,39.31% and 36.53% of the total amino acids,respectively.Their restrictive amino acid was isoleucine.The amino acid scores of FA15-5 and FA15-6 were 31.71% lower and 25.00% higher than that of FA15 respectively.The EAAI value,biological value and nutrition index of mutant strain FA15-6 were 39.97%,54.73% and 40.00% higher than those of the parent strain FA15 respectively.In conclusion,FA15-6 was a better mutant strain with better nutritional value than the parent strain FA15.
