Sumario:Pesticides are substances or mixtures of substances intended to prevent, destroy or control any pest, and they are widely used mainly in agriculture, industry and the domestic sector. These compounds have been extensively used for decades and have significantly increased food production. However, a large amount of applied pesticides often never reach their intended target due to their degradation, volatilization and leaching, resulting in serious environmental problems. This article reviews the main problems that the use of these compounds causes to the environment and health and discusses the basis for biodegradation that can be used for remediation of contaminated sites. It also provides information about the cell immobilization of specific microorganisms on different types of supports, as a strategy to increase the efficiency of pesticide degradation. We also review and discuss the use of biobeds as an economic, clean and efficient strategy to provide a tool for the in situ degradation of pesticide residues.
