Occurrence of branched fatty acid methyl esters The methyl-branched fatty acids are extensively distributed in the nature (Carballeira et al., 2001; Nechev et al., 2002). Now is recognized, that they are formed by the selective incorporation of the methylmalonyl-CoA, catalysed by the fatty acid synthetase enzyme (Seyama et al., 1981), and that such bioenergetic pathway is characteristic from bacteria that generate relative higher concentrations of those isomethylbranched fatty acids. That are, hence, accepted as molecular markers in the organic matter developed by bacteria (Kaneda, 1991; Zabeti et al., 2010). Consequently, the i.
