Studies on air-borne fungi at Qena. II. Diurnal fluctuations.
The air-borne fungi displayed diurnal periodicities. The total count of fungi exhibited double-peaked pattern, one at 6 a.m. and the other at 18 p.m. (the higher). Aspergillus diurnal activities were almost parallel to those of total fungi. Cladosporium showed on main peak at 18 p.m. Penicillium and Alternaria displayed some pattern of diurnal activity and their maxima were observed.
