The micro-organisms comprising bacterial communities play an important role in the biological, geological and chemical dynamics of marine ecosystems, yet it is understudied. Microorganisms which are unique to each ecosystem underpin most of the geochemical cycles that were once previously thought to be driven by inorganic processes. The microorganisms function by forming symbiotic relationships with eukaryotes, communicating with other microorganisms, acquiring nutrients and producing energy. By identifying the microbial community and their function within an ecosystem we will be able to isolate and reproduce the beneficial bacteria needed for the healthy growth of a particular ecosystem. In this study, three coastal ecosystems (coral reef, seagrasses and mangrove forest) in the Bon Accord Lagoon, Tobago were sampled, and their microbial community will be described. This study has never been conducted in Trinidad and Tobago and will be useful in the rehabilitation of the ecosystems which are currently under threat.
