Studies on polyol function in Aspergillus clavatus: a role for mannitol and

Sugars produced by Aspergillus clavatus during growth on radioactive glucose were studied in order to establish roles for the major polyols in the general metabolism of the organism in submerged culture. From 3H/14C isotope-ratio patterns, it is concluded that the predominant function of mannitol is that of a storage compound, possibly connected with conidiation, while ribitol appears to be primarily involved in hydrogen-acceptor mechanisms. Isotopic stability of total fatty acids throughout growth was also observed
