Growth of mycobacteria on carbon monoxide and methanol.

Several mycobacterial strains, such as Mycobacterium flavescens, Mycobacterium gastri, Mycobacterium neoaurum, Mycobacterium parafortuitum, Mycobacterium peregrinum, Mycobacterium phlei, Mycobacterium smegmatis, Mycobacterium tuberculosis, and Mycobacterium vaccae, were found to grow on carbon monoxide (CO) as the sole source of carbon and energy. These bacteria, except for M. tuberculosis, also utilized methanol as the sole carbon and energy source.
