[Study of the lipopolysaccharide from a thermosensitive mutant CR-34 T 83 of Escherichia coli K 12].
The structure of the core of the lipopolysaccharide from T 83 mutant of Escherichia coli K 12 CR 34 was partially determined. Using dephosphorylation, enzymic hydrolysis, Smith degradation, methylations and analysis by gas chromatography/mass spectrometry an oligosaccharide sequence was determined with D-glucose, D-galactose and L-glycero-D-mannoheptose as sugar components. The structure which was demonstrated could be that of the characteristic core fragment of the K 12 type lipopolysaccharides from Escherichia coli.
