**3. Conclusions**

Native microalgae isolated from the Peruvian Amazon have a potential biotechnological application in the remotion of diverse chemical pollutants. These microorganisms showed abilities to remove pollutants contained into leachate generated in an open-air garbage dump and from two wastewaters from Iquitos city. In addition, an immobilized version of the microalgae *Chlorella* sp. was capable to remove ammonium efficiently. Finally, a microalgae consortium composed of three microalgae from the genus *Ankistrodesmus* sp., *Chlorella* sp., and *Scenedesmus* sp. was competent to remove the toxic compound ethidium bromide. Together, these experimental pieces of evidence indicate that native microalgae have an excellent potential for removing several pollutants and, consequently, could be used to develop bioremediation technologies based on native microalgae from the Peruvian Amazon.
