Nitrate reductase activity of Mycobacterium tuberculosis and Mycobacterium bovis in the presence of electron donors.

摘要

The activities of the nitrate reductase enzyme of Mycobacterium tuberculosis, M. bovis, and of BCG were assayed with and without addition of electron donors. M. tuberculosis always reduced nitrate; M. bovis did so only in the presence of electron donors, and BCG did not show enzymatic activity.
