Biodegradation of organic contaminants: Overview and examples with polycyclic aromatic hydrocarbons
- National Center for Toxicological Research, Jefferson, AR (USA)
The ultimate usefulness of the Mycobacterium in the bioremediation of PAH-contaminated sediments depends upon its survival and function in diverse ecosystems. The Mycobacterium survived and mineralized PAHs in sediment and water microcosms. Microcosms inoculated with the Mycobacterium showed enhanced mineralization, singly and as components in a mixture for 2-methylnaphthalene, phenanthrene, pyrene, and benzo(a)pyrene. Studies utilizing pyrene as a sole PAH substrate showed that the Mycobacterium survived in microcosms for six weeks in both the presence and absence of PAH exposure. The versatility of the PAH-degrading Mycobacterium and its potential for use in the bioremediation of PAH-contaminated sediments are discussed.
