How is dechloromonas aromatica used in bioremediation?
Initial interest in Dechloromonas aromatica strain RCB arose from its ability to anaerobically degrade benzene. It is also able to reduce perchlorate and oxidize chlorobenzoate, toluene, and xylene, creating interest in using this organism for bioremediation.
What does benzene degrade into?
Benzene‐degrading organisms contain mono‐ or dioxygenases which activate the aromatic nucleus by introducing molecular oxygen to yield phenol or cis‐benzene dihydrodiol, compounds that are further oxidized to catechol (Gibson and Parales, 2000; Tao et al., 2004).
Where is Dechloromonas aromatica found?
Dechloromonas aromatica is a gram negative, facultative anaerobe bacterium from the genus of Dechloromonas which was isolated of the Potomac River sludge in the mid-Atlantic coast of the United States and occurs in environment soil.
Which bacteria can degrade naphthalene?
Bacteria such as Pseudomonas putida, Rhodococcusopacus, Mycobacterium sp., Nocardia otitidiscaviarum, and Bacillus pumilus have been reported to biodegrade naphthalene.
Is Naphthalene a liquid?
Naphthalene (NAF-thuh-leen) is a white crystalline volatile solid with a characteristic odor often associated with mothballs. The compound sublimes (turns from a solid to a gas) slowly at room temperature, producing a vapor that is highly combustible.
How is Dechloromonas aromatica ( RCB ) used in bioremediation?
Initial interest in Dechloromonas aromatica strain RCB arose from its ability to anaerobically degrade benzene. It is also able to reduce perchlorate and oxidize chlorobenzoate, toluene, and xylene, creating interest in using this organism for bioremediation. Little physiological data has been published for this microbe.
Where can you find Dechloromonas aromatica in sediment?
Dechloromonas aromatica have rod shaped cells and are found in aquatic and aquatic sediment habitats. They can oxidize aromatic compounds such as toluene, benzoate, and chlorobenzoate. D. aromatica strain RCB was isolated from Potomic River sediment, Maryland, USA.
Which is electron acceptor does Dechloromonas aromatica use?
Their research also revealed that Dechloromonas aromatica strain RCB can also use toluene, ethylbenzene, and xylene as electron donors when nitrate is used as an electron acceptor. On top of that, Dechloromonas aromatica strain RCB can degrade benzene and toluene simultaneously.
What is the purpose of the genus Dechloromonas?
In summary, the Dechloromonas represents a unique genus with a broad range of novel metabolic capabilities and bioremediative applicability. Although this genus was only recently described (1), there are now several members in pure culture (1, 8).
