Abstract

A detailed knowledge on the survival of fecal indicator is essential before the dredged marine soil being reused. Microcosms studies have been carried out to find out the relative survival of Escherichia Coli (E. Coli) in dredged marine soils. Survivals of E.Coli were carried out using dredged marine soils collected at Semerak Lagoon, Tok Bali, Kelantan. The experiment was conducted in the flask filled with dredged marine soils and exposed to natural sunlight for 4 hours. Temperature was ranging between 28⁰C and 35⁰C. Experiment in the dark was conducted to isolate the effect of sunlight radiation from the other factors, also to determine the effect temperature on the survival of E. Coli. The variability of E.Coli survival due to the effect of natural sunlight was shown to depend on the variability of the temperature. It is noted that the natural sunlight radiation was found to be one of the factors affecting the survival of E. Coli in dredged marine soils.
