Amino Sugars in the Wall of Pseudomonas fluorescens

SUMMARY: 3-Amino-3,6-dideoxy-d-galactose has been identified as a component of the wall of Pseudomonas fluorescens (nctc10038). This amino sugar was present in the lipopolysaccharide fraction of the wall: other amino compounds present were glucosamine, galactosamine, quinovosamine, alanine and ethanolamine. The distribution of amino sugars within different regions of the lipopolysaccharide was studied briefly.
