Abstract：
In the current study, fifty-eight Ingoldain fungal species assignable to forty-one genera were recovered from two water bodies receiving the treated sewage and the effluents of oils and soaps factory at Assiut Governorate (Upper Egypt), of which Anguillospora, Amniculicola, Flagellospora, and Mycocentrospora were the most prevalent genera. The most widespread identified species were Anguillospora furtive, Amniculicola longissima and Flagellospora fusarioides. Forty-three species were identified for the first time in Egypt. The most Ingoldain taxa were estimated for El-Zinnar canal, with the highest recorded taxa in winter. Whereas, the highest dominance of Ingoldian fungi was estimated for the El-Ibrahimia canal. The highest Simpson and Shannon diversity indexes were estimated for El-Zinnar canal samples recording 0.9683 and 3.741, respectively. The poorest water sites with Ingoldian fungi were those exposed directly to either treated sewage or industrial effluents, with which relatively higher values of water conductivity, cations and anions. Water temperature was the main abiotic factor driving the seasonal occurrence of Ingoldian fungi. It is interesting to isolate some Ingoldian fungal species from the stressful water sites receiving the effluents which provide valuable insights regarding their adaptation, predictive and putative role as bioindicators and their potentiality in pollutants degradation, organic decomposition, and transformation of xenobiotic compounds.
摘要：
在目前的研究中,从两个水体中回收了属于41属的58种Ingoldain真菌物种，这些水体接收了阿西乌特省（上埃及）的处理过的污水以及油和肥皂工厂的废水，其中安吉洛斯波拉，Amniculicola,Flagellospora,和霉囊虫是最普遍的属。发现的最广泛的物种是偷偷摸摸的Anguillospora，长角虫和长角虫鞭毛。在埃及首次发现了43种。估计El-Zinnar运河的英戈丹类群最多，冬季记录的分类群最高。然而,在El-Ibrahimia运河中，Ingoldian真菌的优势度最高。对于El-Zinnar运河样品，估计出最高的Simpson和Shannon多样性指数，分别记录0.9683和3.741。Ingoldian真菌最贫穷的水域是直接暴露于处理过的污水或工业废水的水域，相对较高的水电导率值，阳离子和阴离子。水温是驱动Ingoldian真菌季节性发生的主要非生物因素。有趣的是，从接收废水的压力水站点中分离出一些Ingoldian真菌物种，这些废水提供了有关其适应的宝贵见解，作为生物指示剂的预测和推定作用及其在污染物降解中的潜力，有机分解，和异生化合物的转化。
