Earlier work characterizing the effects of glucose analogs on growth and aflatoxin production by Aspergillus parasiticus was expanded by assessing the effects of β-methylglucose (βMG), 3-0-methylglucose (3MG) and thioglucose (TG). As sole carbon source of conidia-initiated cultures, βMG and 3MG, but not TG, supported growth, but none supported toxin production. In glucose-containing replacement cultures, MG appeared to stimulate toxin production, while TG was inhibitory and 3MG had no effect. Preliminary assessment of the effects of βMG, 3MG, TG, 2-deoxyglucose and α-methylglucose on glucose uptake and utilization by glucose-containing replacement cultures indicated that under conditions that favor aflatoxin production, none of the analogs inhibited the uptake of 14C-labelled glucose. It appears that the glucose transport system(s) of A. parasiticus may be unusual in that it is insensitive to a variety of glucose analogs.
