Regulation of the Salmonella typhimurium aroF gene in Escherichia coli.

abstract：:Achromobacter xylosoxidans strain A8 was isolated from soil contaminated with polychlorinated biphenyls. It can use 2-chlorobenzoate and 2,5-dichlorobenzoate as sole sources of carbon and energy. This property makes it a good starting microorganism for further development toward a bioremediation tool. The genome of A....
