    Author: el-Nagdy MA, Abdel-Hafez SI.
    Journal: J Basic Microbiol; 1990; 30(4):233-40. PubMed ID: 2384873.
    Abstract:
    Thirty-nine species belonging to 13 genera of zoosporic fungi were collected from 33 water samples on sesame and hemp seeds as baits at 22 degrees C. Five genera were isolated in high occurrence: Allomyces (2 species), Achlya (9 species), Dictyuchus (4 species), Pythium (5 species) and Saprolegnia (5 species). Aphanomyces (4 species) and Isoachlya (2 species) were of moderate frequencies. The remaining six genera were less frequent: Anisolpidium, Brevilegnia, Calyptralegnia, Leptolegnia, Pythiopsis and Thraustotheca. Sixty-six species and 2 varieties belonging to 34 genera were identified on glucose-(24 genera and 52 species + 1 variety) and cellulose (31 genera and 48 species + 2 varieties) Czapek Dox agar at 28 degrees C. The most common species on the two media were Acremonium strictum, Aspergillus flavus, A. fumigatus, A. niger, Fusarium moniliforme, F. oxysporum, F. solani, Mucor racemosus, Penicillium chrysogenum and P. corylophilum. Some fungi were common only on cellulose agar medium such as Chaetomium globosum, C. spirale and Memnoniella echinata.
