The present study was confined to the marine ecosystem in and around Mamallapuram coast, Tamil Nadu comprising of Mammallapuram and Water, sediment, and natural substrates of marine ecosystem were collected to isolate the fungi. All the collected samples were plated, incubated and the fungal colonies were identified. The water and sediment sample were collected separately and analysed for temperature, pH, biological oxygen demand, salinity and total dissolved solids on water. A total of 41 fungal species were isolated and enumerated by plating, techniques. In this study, 24 species of fungi were recovered from sediment samples whereas water samples yielded 30 species and natural substrates with 24 species. Among the Hyphomycetes, Aspergillus was the common genus represented by 14 species followed by Penicillium and Cladosporium. Totally, 10 species of fungi were used for hydrocarbon studies. The growth pattern of fungi in diesel is T.viride had a maximum growth 24mm with A. sulphueus had the least growth growth on the 5th day at 9 mm with A.niger. The growth pattern of fungi in petrol is P.citrinum had maximum growth on the 5th day at 90mm and minimum with 9 mm by R.oryzae. The growth pattern of fungi in Crude oil shown A.flavus had a maximum growth at on the 5th day mm and minimum growth rate was observed in A.oryzae with 9 mm. The growth pattern of fungi in kerosene is P.janthinellum had a maximum growth at 27 mm and the lowest growth rate in A. oryzae with 5 mm.
