When something harmful enters the environment at a faster rate that it can be dispersed, there is pollution. The fundamental idea behind bioaugmentation is to confer a desired degradation or transformation function to a contaminated medium. GEM is a powerful tool in creating environment friendly alternatives for products and processes For e.g. Learn more. 1977;268:732–733. As soon as the prospect of releasing genetically modified microorganisms for bioremediation became a reality, much of the research effort in the field was aimed at biosafety and risk assessment . Biomicrofluidics. In this chapter, we describe various techniques for the development of genetically modified microorganisms along with different examples of recombinant produced. 2014 May;12(5):368-79. doi: 10.1038/nrmicro3253. Dealing with pollution. The massive mobilization of compounds stored in natural resources, or the introduction of xenobiotics into the biosphere, leads to unidirectional fluxes, which result in the persistance of a number of chemicals in the biosphere, and thus constitute a source of pollution.
