Abstract :
The alkali extractable and water-soluble cell wall polysaccharides F1SS from Aspergillus wentii and Chaetosartorya chrysella have been studied by methylation analysis, 1D- and 2D-NMR, and MALDI-TOF analysis. Their structures are almost identical, corresponding to the following repeating unit: [--> 3)-beta-D-Gal f -(1 --> 5)-beta-D-Gal f-(1 -->]n --> mannan core. The structure of this galactofuranose side chain differs from that found in the pathogenic fungus Aspergillus fumigatus, in other Aspergillii and members of Trichocomaceae: [--> 5)-beta-D-Gal f-(1 -->]n --> mannan core. The mannan cores have also been investigated, and are constituted by a (1 --> 6)-alpha-mannan backbone, substituted at positions 2 by chains from 1 to 7 residues of (1 --> 2) linked alpha-mannopyranoses.Copyright 2004 Kluwer Academic Publishers
