Isolation and Identification of Fungi and Fungus-like Organisms from Sewage Water and soil edge sewage water in the Erbil City

Abstract

Abstract This study was carried out in Mycological –Laboratory Department of Biology –College of science during spring and autumn season in 2012. This study aims to survey fungi and fungus –like organisms from Sewage water and edge soil sewage water, in Erbil city. Certain physico-chemical parameters of water were performed following standard methods. Five sites at different locations along sewage waterway for 25km distance were chosen for this study. They baiting technique was used by (seed) and dilution method to the soil for isolation of fungi, used API 20C AUX and VITEK2 system to identifying yeasts. During spring (27) species isolated were belong to (14) genera, the most frequents isolated fungi were Geotrichium spp , Verticillium sp., and Fusarium spp . While during autumn isolate (34) species belong to the (17) genus, Most frequently fungi isolated were Fusarium spp , Trichoderma sp, Rhizopus sp, and Aspergillus sp. present results indicated the diversity of fungi and fungus –like organisms which isolated from edge soil of sewage water by dilution method during both seasons, (107) species belong to (37) Genera isolated, among these which they Aspergillus spp (70 x1000) cfu\g.soil Fusarium spp (94x 1000)cfu\g.soil, Geotrichium spp (65x1000)cfu g.soil , the minimum isolated fungi were Torula sp. , Archnophora sp. , Aristatoma sp. ,Bahnsakala sp. Harpographium sp., Phialophora sp. , Arthrospora sp ., Aureobasidium sp. , Myrothecium sp. , Pythium sp. and Xylohyph sp. for each (1 x1000)cfu \g.soil .
