Abstract Gas-liquid chromatography of cellular fatty acids is a useful tool for the identification of bacteria. Derivatization of bacterial fatty acids to methyl esters by conventional techniques is usually time-consuming and complicated. A new one-step technique using trimethyl-sulfonium hydroxide allows the direct formation of fatty acid methyl esters within 1-2 min. Some random examples of profiles demonstrate that straight, branched, saturated, unsaturated, hydroxy and cyclopropyl fatty acids match conventional preparations well. The method is a very sensitive one, since only a few colonies are sufficient for preparation of fatty acid methyl esters.
