On the Bioremediation Potential of Inhabitant Microbes of Dredged Marine Soils: A Theoretical Framework

Abstract:

Biological degradation is one of the most beneficial and economical methods to clean up contaminated marine soils. Although biodegradation by microorganisms encourages the natural process of contaminant removal and serve as potentially cost-effective treatment, limited facts in microbes and contaminant interactions lead in treatment failure. The present study had identified the existence of potential microbes in marine soils dredged from the coasts of Peninsular Malaysia. These included the genera of Serratia, Vibrio, Enterobacter, and Pseudomonas. Among these, Vibrio and Serratia have potential to degrade oil and grease as well as Polycyclic Aromatic Hydrocarbons (PAHs). Irrespective of any additions of particular nutrients, the existence of these genera whereupon reduces the potential for bioaugmentation treatment. Major problem in bioaugmentation is rapid decline in number of introduce microbes due to abiotic or biotic stress. The first stage needed to develop treatment strategies are by understanding the environmental conditions and factors that limit the ability of microbes to degrade the contaminants. Considering these understanding, biodegradation treatments of contaminated dredged marine soils is ease to design. This theoretical framework therefore aims to assess on the bacteria capability to degrade correlated with the contaminant concentration.
