Structural elucidation of the core-lipid A backbone from the lipopolysaccharide of Acinetobacter radioresistens S13, an organic solvent tolerant Gram-negative bacterium
چکیده انگلیسی

The structure of the core oligosaccharide of the lipopolysaccharide from an organic solvent tolerant Gram-negative bacterium, Acinetobacter radioresistens S13, was investigated by chemical analysis, NMR spectroscopy and MALDI-TOF mass spectrometry. All the experiments were performed on the oligosaccharides obtained either by alkaline degradation or mild acid hydrolysis. The data showed the presence of two novel oligosaccharide molecules containing a trisaccharide of 3-deoxy-d-manno-octulopyranosonic acid in the inner core region and a glucose rich outer core whose structure is the following: R = H in the main oligosaccharide and β-Glc in the minor product.The bacterium was grown on aromatic (phenol and benzoic acid) and nonaromatic carbon sources and the core oligosaccharide resulted to occur always with this novel structure.
