Abstract

Prevalence of keratinophilic fungi was observed in paddy field soil during different stages of cultivation viz., transplanting, tillering, milking and maturation. Out of total 76 soil samples, 65 soil samples were found to be positive for the keratinophilic fungi. Fourteen species belonging to a single genus Chrysosporium were isolated through out the cropping season. C. keratinophilum (17.1%) followed by C. tropicum (13.15%) were found to be the most dominating geophilic species. The highest percent distribution of keratinophilic fungi appeared during the milking stage (100%) of paddy cultivation, followed by the maturation stage (89.47%).

摘要

在稻田土壤种植的不同阶段，即移栽期、分蘖期、灌浆期和成熟期，均观察到嗜角质真菌的存在。在总共76份土壤样本中，发现65份土壤样本的嗜角质真菌呈阳性。在整个种植季节分离出了属于单属金孢子菌属的14个物种。发现嗜热栖金孢子菌（17.1%）其次是热带金孢子菌（13.15%）是最主要的土栖物种。嗜角质真菌的最高百分比分布出现在水稻种植的灌浆期（100%），其次是成熟期（89.47%）。
