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)-β-D-Galf-(1→5)-β-D-Galf-(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)-β-D-Galf-(1→](n)→mannan core. The mannan cores have also been investigated, and are constituted by a (1→6)-α-mannan backbone, substituted at positions 2 by chains from 1 to 7 residues of (1→2) linked α-mannopyranoses.
