    摘要: A process for remediation of contaminated solid materials comprising polynuclear aromatic hydrocarbon contaminated solid materials, polychlorinated hydrocarbon contaminated materials, and mixtures thereof by sequential biological/chemical/biological treatment in which the contaminated solid materials are biodigested under suitable conditions by a first aerobic or anaerobic digestion, producing a first biodigestion product. The first biodigestion product is then contacted for chemical treatment with hydrogen peroxide in the presence of ferrous ion in amounts and under conditions suitable for chemical oxidation, forming a mixture and oxidizing the first biodigestion product, producing biodegradable hydrocarbon product materials having enhanced biodegradability. The product materials are then biodigested under suitable conditions by a second aerobic or anaerobic digestion.

    摘要: The present invention provides methods, nucleic acid constructs, and kits for selectively deleting a region of a nucleic acid sequence. Specifically, it utilizes retargeting retroelements to place site-specific recombination sites at targeted locations in the nucleic acid sequence. The region between the recombination sites is then deleted using a site-specific recombination system.
