Bioremediation is a biological mechanism that recycles waste that can be reused and reused by other organisms. Nowadays, the world is facing the problem of different environmental pollution. Microbes are essential to an important alternative solution to overcoming challenges. Microbes live everywhere in the biosphere because their metabolic function is astonishing; Environmental conditions are present in all. The nutritional potential of microorganisms is completely different, so it is used as a biofilm of environmental pollutants. Bioremediation is highly involved in the decomposition, elimination, immobilization or toxicity of various chemical wastes and physically hazardous substances from the surrounding all-encompassing and functional microorganisms. The main policy is to degrade and replace pollutants such as hydrocarbons, oil, heavy metal, pesticides, and dyes. It is carried out in an enzymatic way by metabolism, so it has a role to play in solving many environmental problems. There are two types of factors that determine the rate of deterioration of biological and agiotic conditions. Currently, different methods and techniques are used in different parts of the world. For example, biostimulation, bioaccumulation, bioventilation, biopiles and bioautenuation are common. All biological techniques have their own advantages and disadvantages because it has its own specific application.
