Abstract
The present work represents an extensive sury on zygomycetous fungi in different microhabitats in egypt covering soil,animal dung, seed& grains and air.enzymatic activites of the isolated fungi were evaluated. The sensitivity of zygomycetes to antifungal agents and essential oil was also tested. The following main results have been achieved :
1- A total of 18 identified in addition to two unidentified species belonging to 11 fungal genera were isolated in this investigation.
2- Mycological analysis of 100 soil samples revealed the isolation of 17 species and 10 genera of Mucorales. The most common genera were Absidia, Mucor and Rhizopus (37%, 63%, and 73% of total samples, respectively).
3- Rhizopus stolonifer was the most common species (62% of samples) whereas Mucor circinelloides, M. hiemalis and R. oryzae were of moderate incidence colonizing 27.5, 33% and 34% of soil samples, respectively.
4- Dung samples produced 11 species belonging to 7 genera of zygomycetes of which Absidia, Mucor and Rhizopus were the prevalent genera appearing in 42%, 80% and 62% of samples, respectively. This means higher frequency of Mucor in dung than soil.
5- Some fungi which were of low incidence in soil were moderately encountered from dung samples, examples are Absidia corymbifera, Actinomucor elegans, Apophysomyces elegans, Cunninghamella echinulata and Mucor racemosus.
