| Abstract: | The qualitative and quantitative composition of purifed cell wall of Halococcus morrhuae CCM 859 was determined. Glucose, mannose, galactose; glucuronic and galacturonic acids; glucosamine, galactosamine, gulosaminuronic acid; acetate, glycine and sulfate are found as major constituents. The amino sugars are N-acetylated. It was not possible to fractionate the cell wall in chemically different polymers. Evidence is presented that the major cell wall polymer of this strain is a complex heterolgycan which seems, like the peptidoglycan of most bacteria, to be responsible for the rigidity and stability of the cell wall. In addition it could be proved that this heteroglycan is sulfated and therefore differs considerably from previously described bacterial cell wall polymers. |
