The wetlands are unique ecological sites which play a substantial role in the environment relating to its unique characteristics of biology, hydrology, and ecology. Wetlands provide a transition between the aquatic and terrestrial life forms, hence providing huge carrying capacity for all kinds of organisms. Soil plays an important role in any water body right from storage of the pollutant to the release of those pollutants. There are many characteristics of the soil which governs the behaviour of pollutants among them are micro-organisms. The wetland soil is highly saturated with low oxygen content hence it becomes a perfect habitat for diverse bacterial communities. The rhizobacteria are mainly responsible for the leaching of heavy metals from the soil. The low molecular organic acids which were released by the rhizobacteria in the soil helps in leaching the heavy metals, and this leads to one of the characters of bioavailability to the plants. In this study, the soil bacteria have been classified for the wetland in south Chennai, India, regarding its abilities to enhance the phytoremediation process. DNA extraction technique was adopted followed by 16srna in identifying the bacteria. The results yielded eight different bacterial species of Proteobacteria, Firmicutes, and Actinobacteria phylum. The bacterial diversity helps to understand the bioavailability phenomena to the plants and also in finding out the best effective bacteria to use in the bacterial assisted phytoremediation studies.
