PETROLEUM DEGRADATION IN LOW TEMPERATURE MARINE AND ESTURBINE ENVIRONMENTS
Enrichment of hydrocarbon and fuel oil utilizing bacteria was shown following an oil spill in Narragansett Bay and chemical analyses of sediments from the spill site confirmed the role of biodegradation. Biodegradation did occur during the winter months at a rate of 1-1.8 mu g of hydrocarbon per gram of sediment per day. Laboratory culture and BOD methods showed degradation rates higher than the measured in situ rates but demonstrated the presence of psychrophilic hydrocarbon metabolizing micorbial populations in the natural environment during the winter. Laboratory Q sub 10 values at 10 and 20 deg C for psychrotolerant isolates were less than 2.0. Filamentous fungi were isolated which metabolized petroleum hydrocarbons with the formation of inclusions peculiar to hydrocarbon grown cultures.
