Methyl glucose lipopolysaccharides (MGLP)were first isolated in 1964 from a fast growing, nonpathogenic mycobacterial strain, Mycobacterium smegmatis. Their complete structure was achieved in 1982 by Forsberg et al.2 It was established that the M. smegmatis MGLP heterogeneity arises from the acyl appendages borne by the polysaccharidic core. In the present study, we report the occurrence of MGLP from a slow growing strain M. xenopi and the structure of the deacylated derivatives (MGP). A new analytical strategy, based on the use of High h]pH Anion Exchange liquid Chromatography (HPAEC) and Liquid Secondary Ion Mass Spectrometry (LSIMS) was successfully develiped. Thanks to HPAEC, the MGP mixture was fractionated and from LSIMS data, it was clearly established that the heterogeneity of the MGP polysaccharidic core arises from the number of glycosyl and methoxyl units.
