Abstract

In the dimorphic zygomycetous fungus Benjaminiella poitrasii, the cell wall compositions of mycelial phase (M), yeast phase (Y) and its yeast form mutants (Y-2 and Y-5) were studied. Chitosan was abundant in M-phase (26.6%) whereas lesser amounts were present in Y-phase (17.3%) and in mutants Y-2 (19.6%) or Y-5 (17.3%). Although chitin was present as a smaller fraction of the total glucosaminoglycan in each of different cell wall preparations, it was almost 3 times more prevalent in M-phase than the Y-phase cells. Cross-linking studies among the various cell wall components in B. poitrasii, suggest linkages among mannans and proteins and glucans and glucosaminoglycans.
