Abstract/OtherAbstract:
A simple and sensitive method for separating and detecting the LL, DD and meso diastereomers of the dibasic amino acid diaminopimelic acid (DAP) in the peptidoglycan of Gram-positive bacteria is described. This method is based on reverse phase HPLC separation of chiral derivatives of DAP followed by fluorescence detection of the o-phthaldehyde derivatives. Its application to the analyses of cell walls of several Gram-positive bacteria is described, where 10 mg or less of dry cells is required.
