Abstract

The mineralization of organic molecules by microbes is essential for the carbone cycle to operate. The massive mobilization of compounds stored in natural resources or the introduction of xenobiotics into the biosphere produces unidirectional fluxes that result in the persistence of many chemicals in the biosphere, where they are a source of pollution. Molecular biology offers the tools to optimize the biodegradative capacities of microorganisms, accelerate the evolution of new metabolic activities, and construct totally new pathways through the assemblage of catabolic segments from different microbes.
