| mycolic acid patterns of some rapidly-growing species of mycobacterium. | representative strains of some rapidly-growing species of mycobacterium were degraded by both acid methanolysis and alkaline hydrolysis followed by phase-transfer catalysed conversion to methyl esters. patterns of mycolic acids and other long-chain components were determined for 56 samples by two-dimensional thin-layer chromatography. representatives of mycobacterium chitae contained epoxymycolates and alpha and alpha'-mycolates, lacking oxygen functions in addition to the 3-hydroxyacid unit; a ... | 1985 | 4050199 |
| two new mycobacterium strains and their role in toluene degradation in a contaminated stream. | two toluene-degrading strains, t103 and t104, were isolated from rock surface biomass in a freshwater stream contaminated with toluene. the strains exhibit different capacities for degradation of toluene and other aromatic compounds and have characteristics of the genus mycobacterium. both are aerobic, rod-shaped, gram-positive, nonmotile, and acid-alcohol fast and produce yellow pigments. they have mainly straight-chain saturated and monounsaturated fatty acids with 10 to 20 carbon atoms and la ... | 1998 | 9572941 |
| mycobacterium tusciae sp. nov. | a new, slow-growing, scotochromogenic mycobacterium was isolated from a lymph node of an immunocompromised child and subsequently from tap water and from a respiratory specimen of a patient with chronic fibrosis. alcohol-acid-fastness, lipid patterns and the g + c content clearly support the placement of this organism in the genus mycobacterium. the isolates grew very slowly at temperatures ranging from 25 to 32 degrees c and showed activities of nitrate reductase, catalase, urease, arylsulfatas ... | 1999 | 10555367 |
