The fibrillar polysaccharides and their linkage to algaenan in the trilaminar layer of the cell wall of Coelastrum sphaericum (Chlorophyceae)

Methylation and spectroscopical analyses of DMSO-LiCl-solubilized fractions of the fibrillar cell wall of Coelastrum sphaericum Nag. established the presence of cellulose and β-1,4-linked mannan. A small proportion (2-7%) of (1→2) linkages in β-mannan that introduced an interruption in the regular r...
