Functional diversity of <i> <scp>N</scp> ocardia </i> in metabolism

Summary Bacteria affiliated in the genus N ocardia are aerobic and G ram‐positive actinomycetes that are widely found in aquatic and terrestrial habitats. As occasional pathogens, several of them cause infection diseases called ‘nocardiosis’ affecting lungs, central nervous system, cutaneous tissues and others. In addition, members of the genus N ocardia exhibit an enormous metabolic versatility. On one side, many secondary metabolites have been isolated from members of this genus that exhibit various biological activities such as antimicrobial, antitumor, antioxidative and immunosuppressive activities. On the other side, many species are capable of degrading or converting aliphatic and aromatic toxic hydrocarbons, natural or synthetic polymers, and other widespread environmental pollutants. Because of these valuable properties and the application potential,
