The biological value of proteins from 3 carboxidobacterial strains was assessed on the basis of the protein amino acid content, consumption by the test-organism T. pyriformis and protein susceptibility to proteolytic enzymes in vitro. Carboxidobacterial proteins are characterized by a full-value amino acid composition and contain large amounts of all indispensable amino acids. This indicates that on the whole these proteins are quality ones. Experiments with the test-organisms have shown, however, that the relative biological value of the protein samples significantly yields to casein. The total digestibility of carboxidobacterial proteins by pepsin and trypsin in vitro is close to that of wheat vegetable proteins and lower as compared with that of casein. Carboxidobacterial proteins may be thus attributed to a protein group being an intermediate one between casein and wheat vegetable proteins. |
