The Role And Functions Of Bacteria In The Community

Bacteria are found everywhere around us and many of which are beneficial to the environment and humans, assisting in protecting the biodiversity of ecosystems within an urbanized environment. This paper aims to determine the role and functions of bacteria found within the ponds of Centennial Park in relation with other bacteria and eukaryotes. This was achieved through the process of traditional and modern microbiological techniques of gram staining, biochemical tests and 16s rRNA analysis of bacterial DNA to help classify the different bacterial isolates. Heterotrophic proteobacteria were mainly found which countered algal blooms within the pond by reducing nutrient levels, assisted in bioremediation, decomposed debris and assisted in…show more content…
Also, as the pond is surrounded by anthropogenic activity, water pollution from heavy traffic and pollutants from storm water runoff is common, harming not only the flora and fauna but also humans. Therefore, it is important to gain an idea of the overall pool of microorganisms within an aquatic ecosystem.
Furthermore, by understanding the different roles bacteria play in a natural aquatic environment, we can then apply our understanding of industrial microbial ecosystems such as open ponds and aquacultures to ponds. For instance, Beyer et al. showed that the “diverse metabolic activities of microbes are essential to maintaining a stable, productive ecosystem for biomass production in algae open ponds”. Similarly, microorganisms are essential within aquaculture, “preventing unwanted algal bloom and pathogens and improving water quality.” Conversely, we can also use the methods applied in aquacultures which control for pathogens and water quality via bioremediation and bioaugmentation within a natural aquatic environment. Through this study, we can then predict what further action is to be taken to maintain a healthy ecosystem.
In this study, we analysed the bacterial composition of the ponds of Centennial Park and understand their importance within such a diverse ecosystem. We extracted DNA from the ponds of Centennial Park using the 16s ribosomal RNA to gain an overview of the diversity of the bacterial taxonomic levels.
