Abstract
The main polysaccharide fractions from cell wall material of several geophilic dermatophyte species were characterized as a glucomannan (F1S) which amounted to 4.0–6.5% and a glucan-chitin complex representing 44.2–71.0%. The neutral sugar content of fraction F1S in these species was mannose (38.7–78.2%), galactose (0.3–7.3%) and glucose (3.2–8.2%) except inM. fulvum (21.9%) andE. stockdaleae (12.5%). Small proportions of xylose, about 1%, were found in this fraction except inM. fulvum which reached 7.8% and inM. nanum which lacked xylose. The main products detected after Smith degradation were glycerol and glucose. From fraction F1S ofM. fulvum a glucan (18.3%) and a mannan (41.5%) were obtained. These two polysaccharides could be used as chemotaxonomic characters for the definition of this group of fungi.
