Electron probe microanalysis of cell walls of Cunninghamella echinulata

Hyphal and spore walls of Cunninghamella echinulata (Thaxt.) Thaxt., were examined by electron probe microanalysis. Phosphorus, sulphur, calcium, chlorine and magnesium were positively identified and their presence confirmed by chemical and spectrochemical analysis. Results indicate that polyphosphate in walls of Mucorales is associated with chitosan through an ionic linkage.
