An antigenic water-soluble glucogalactomannan extracted from cell walls of Paecilomyces fumosoroseus and Paecilomyces farinosus

Article Abstract:

A water-soluble galactomannan, extracted from the cell wall of four strains of Paecilomyces fumosoroseus, was isolated and partially characterized. A search of cell-wall polysaccharides revealed the structure of the fractions, which is comprised of a (1->4)-alpha-glucan (F1S-A) and a branched (1->6)-mannan with terminal residues of beta-galactopyranose (F1S-B). The immunogenicity of F1S-B polysaccharides and the specificity of the anti-Fs1-B serum from P. fumosoroseus CBS 375.70 were also determined. Indirect immunofluorescence tests also revealed the staining of fungal hyphae of P. fumosoroseus CBS 375.70.

Intron polymorphism in small subunit rDNA of Nectria galligena

Article Abstract:

The presence of introns responsible for size polymorphisms in the small subunit ribosomal DNA of Nectria galligena was examined. The isolates were divided into four similar but not identical categories using Southern-RFLP analysis. Results showed that the introns lack the core elements characteristic of typical group I introns or group I intron secondary structure. Moreover, homology between the introns which indicate a common lineage, was observed.

Comparison of cell-wall polysaccharides from Nectria cinnabarina with those from the group of Vectria with Sesquicillium anamorphs

Article Abstract:

Cell-wall polysaccharides from Nectria cinnabarina have been compared with those from the group of Vectria with Sesquicillium anamorphs. These polysaccharides are alkali-extractable and water-soluble.
