Abstract

Soil is a complex ecosystem delimited by physico-chemical parameters that hold enormous number of living organisms. This study deals with the seasonal variation of two different environment such as rhizosphere soil from mangrove environment of Muthukuda and salt pan soil from Ammapattinam in Pudukkottai Dt, Tamilnadu. The soil fungi were recorded by both direct examination and plating method. In the direct examination method totally 57 different species belonged to 26 genera were isolated. Among them 5 species were Phycomycetes, 52 were Deuteromycetes. They were isolated by using PDA medium and identified by using standard manuals. The dominant species were Aspergillus conicus, A.humicola, A.sydowi, Penicillium roqueforti, Rhizopus stolonifer, from the mangrove field soil of muthukuda in various seasons whereas in Ammapattinam (Salt pan) soil the dominant species were Aspergillus awamori, A.niger, T.viridae, Fusarium oxysporium, Penicillium citrinum. The different morphological isolates represented by sterile mycelia were isolated by plating method.
