The mycolic acids and fatty acids of mycolic acid- containing bacteria in various types of fluids were analyzed using capillary gas chromatography and mass spectrometry. As model strains, Brevibacterium and Coryebacterium species, which have corynomycolic acids ill the range of $C_{32}C_{36}$ in the whole cell, were investigated. Optimized solvents extraction procedures for the mycolic acids and fatty acids from the culture fluids were: chloroform/methanol (1:2, v/v) as the first extraction solvents fur 4 h; and chlorofunuwater (1:1, v/v) as the second extraction solvents far 1 h. These conditions gave above 95% recovery yields fur mycolic acids from the culture fluids. The mycolic acid profile for the whole cells and the culture fluids were similar fur all the media tested. Thus, the procedure described here could be applied for the identification of mycolic acid-containing bacteria in fermentation broth or liquid from of foods.

RNA 기반 연구에서 고품질의 RNA 추출은 상당히 중요하다. Mycobacterium tuberculosis는 세포벽에 mycolic acid가 풍부하여 두껍고 왁스와 같은 성질을 띈다. 이로 인해 용균이 쉽지 않아 RNA 추출이 어렵다. TRIzol 시약과 silica bead를 이용한 균 파쇄를 통하여 높은 수율의 RNA가 추출이 가능하였다.
