ABSTRACT Eutrophication is a process by which destabilizes the aquatic ecosystem and deteriorates the quality of surface water. In view of this, the insertion of mitigating and restorative measures are indispensable for the conservation of the water body. The objective of this research is to analyze qualitatively how the use of biotechnology associated to bioremediations, acts in the process of recovery of aqueous environments. The method used was inductive, and the research has a basic nature, with a qualitative approach and complemented with data collection in research bases such as the Coordination of Improvement of Higher Education Personnel - CAPES, Scientific Electronic Library Online - SciELO, and Google Scholar, whose time cut was from 2009 to 2018. The data indicated that the quality of the use of bioremediation is effective, either with the application of phytoremediation or other biotechnologies associated or not, and present a lower cost when compared to the existing physical and chemical methods. The data also indicated that microorganisms and plants have specific ways of removing, immobilizing or transforming pollutants from inappropriate effluent releases. It should note that these mitigation and recovery measures are very new alternatives for the context of polluting companies and society as a whole. Therefore, the use of these biotechnologies is important for disseminating ways to regenerate contaminated environments, where they have a low energy cost and do not require direct physical-chemical interventions.
