A comparative analysis of mycobacterial fatty acid fractions of Mycobacteriun habana and Mycobacterium sineae strains was made. This study used the gas-liquid chromatography coupled with mass spectrometry. Chromatographic profiles obtained from this technique were exposed and compared. This technique proves to be valuable as an alternative element in mycobacterial characterization and makes it possible to analyze the possible differences that may exist among mycobacterial species and to identify the present fatty acid fractions. The outcome proved that the studied strains had quantifiable quantities of over 20 C atom chain fatty acids. There are small differences among the strains in terms of these organic components. It was confirmed that each of then describes a characteristic chromatographic pattern although the composition of present fatty acids is very similar in both studied species.
