Abstract
Some moderate and extreme thermophilic bacteria grew well on media other than the recommended basic media. Attempts to induce phenylalanine hydroxylase (Phe H) in various thermophiles and mild thermophily in the mesophiles Pseudomonas sp. ATCC 11299a and Chromobacterium violaceum ATCC 12540 were unsuccessful. The enzyme in the latter 2 organisms may be membrane bound. The level of Phe H activity induced was not always consistent with the level of the inducer Phe in the growth medium.
