Abstract

To isolate keratinophilic fungi in sewage sludge from wastewater treatment plants in Sari city, Mazandaran province, Islamic Republic of Iran, samples were taken from 7 plants with different sewage treatment technologies. From 35 sludge samples cultured on Sabouraud's agar with cycloheximide and chloramphenicol, 326 fungal colonies belonging to 7 species were isolated. Geotrichum (59.5%), Cladosporium (13.8%), Alternaria (11.3%) and Penicillium (10.7%) species were the most prevalent. No growth of keratinophilic fungi was observed on this medium. However, using the hair-baiting technique, Microsporum gypseum, Chrysosporium spp. and Geotrichum spp. were isolated.

摘要

为了分离伊朗伊斯兰共和国马赞德兰省萨里市污水处理厂污水污泥中的嗜角质真菌，从7家采用不同污水处理技术的工厂采集了样本。在含有环己酰亚胺和氯霉素的沙氏琼脂培养基上培养的35份污泥样本中，分离出了属于7个物种的326个真菌菌落。最常见的物种是地霉属（59.5%）、枝孢属（13.8%）、链格孢属（11.3%）和青霉属（10.7%）。在这种培养基上未观察到嗜角质真菌生长。然而，使用毛发诱饵技术，分离出了石膏样小孢子菌、金孢子菌属和地霉属。
