✦ Synopsis

A new metabolite, 6-ethylsalicylic acid, was shown to accompany 6-methylsaiicylic acid in cultures of Mycobacterium phlei grown on media supplemented with propionate. Mass spectral analyses of the aromatic acid fractions obtained after growth in the presence of /?,/?,P-trideuteropropionate demonstrate that the ethyl group derives from propionate. It is postulated that this bacterium can use a propionate 'starter' unit in elaboration of a polyketomethylene chain

In Mycobacterium phlei, fatty acid unsaturation increased with decreasing temperature. The 10-hexadecenoic acid content increased as the temperature was reduced from 35 degrees C to 26-20 degrees C. At lower temperatures tuberculostearic acid decreased while oleic and linoleic acids increased, the l
