Aquatic Pollution Stress and Role of Biofilms as Environment Cleanup Technology

The burden of pollutants in water is growing at an alarming rate. The Pollution load is the chief element responsible for ecological stress in aquatic ecosystems. Causative agents for stress in the aquatic ecosystem are usually heavy metals, limiting or excessive nutrient availability, pesticides, pharmaceuticals and changing water properties. Biofilms are collective populations of microbes embodied in the extracellular polymeric substance and are mostly found on different surfaces. These are good indicators of pollution as well as the best candidates for the treatment of pollution load in water bodies. Microbial populations from biofilm have been successfully characterized and used for bioremediation and removal of nutrients from polluted waters due to their unique mechanism of binding with pollutants and high tolerance limit. Biofilm based bioreactors are in use today for cleaning polluted water and have been proved to be more efficient than conventional pollution treatment plants. In this section an effort has been made to evaluate biofilm as the best available option for environmental cleanup of pollution in aquatic ecosystems.
