Abstract
Abstract The subject invention concerns a novel plasmid and its use in a microbial host to degrade a variety of organic compounds. Some of these compounds, such as ethylene dichloride, are undesirable waste products found in various dump sites. The invention also concerns a novel microbe hosting the novel plasmid. The novel plasmid has been shown to encode the gene(s) responsible for the degradation of the organic compounds. Thus, microbes hosting this plasmid, denoted pEDC, can be used to degrade ethylene dichloride, and other compounds.
