in comparing the fatty acid pattern thus obtained and the known structure of mycolic acids in these mycobacteria , an experiential rule that each species of mycobacteria has a relatively high content of normal ( straight-chained ) saturated fatty acid having two more carbons than those of the alpha-branch in this species ' mycolic acids , coincided well for all mycobacteria tested .
