A new metabolite, 6‐ethylsalicylic acid, was shown to accompany 6‐methylsalicylic 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 β,β,β‐tridenteropropionate 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.
