Isolation, Identification and Seasonal Distribution of Soilborne Fungi in Different Areas of Erbil Governorate
Keywords:Soil fungi, Aspergillus sp., Washing method
A survey study was undertaken for the isolation and identification of soilborne fungi inhabiting different areas in Erbil, Iraq. A total of 15 soil samples collected seasonally during August 2008-July 2009.
Fungi were isolated from soil during this study's period, by soil dilution plate method on selective medium: Potato Dextrose Agar (PDA), eighty-one different genera of fungi were isolated during the four seasons; (30, 33, 70, and 53) genera isolated in (summer, autumn, winter and spring) respectively, the most frequently isolated fungi during four seasons were Aspergillus sp. (539x103) colony forming units /g.soil, followed by Penicillium sp. (215x103) cfu/g.soil, Rhizopus spp. (115x103) cfu/g.soil, Emericella spp. (109x103) cfu/g.soil, Fusarium spp. (47x103) cfu/g.soil, and Ulocladium botrytis (47x103) cfu/g.soil, while the least frequently isolated fungal genera were Blakeslea tuningtam, Clasterosporium cyperi, Idriella sp., Naranus cryptomeriae and Torula alternata, (1x103) cfu/g.soil, for each one.
Fungi isolated from soil by washing method counted for ninety three species belonging to fifty six genera, among them: Aspergillus sp., Circinella sp., Cunninghamella sp., Mucor spp., Mycelia sterilia, Rhizopus sp.
