Cell wall polysaccharides isolated from the fungus Neotestudina rosatii, one of the etiologic agents of mycetoma in man.
The alkali-extractable water-soluble polysaccharides F1SS isolated from the cell wall of two isolates of the pathogen Neotestudina rosatii and one of Pseudophaeotrichum sudanense, which is now considered as a synonym of the former, have been studied by methylation analysis, GC-MS and NMR spectroscopy. The three polysaccharides differ mainly in their content in galactofuranose, and have the following idealized repeating unit: with m approximately 19, and p approximately 6 in all cases, but being n approximately 1 for N. rosatii CBS 271.75, n approximately 0.5 for N. rosatii CBS 331.78, and n approximately 0.15 for P. sudanense.
