The objective of this study was to assess the current state of knowledge regarding the effectiveness of available technologies to decontaminate or treat the air, equipment surfaces, wastewater, and sludge at the facilities that process biologically active materials such as genetically engineered microorganisms. Since published literature on the inactivation of these recombinant-DNA (rDNA) organisms is very limited, data for representative naturally occurring microorganisms (bacteria, viruses, and fungi) and their subcellular components were obtained through an extensive literature search. The data indicate that ozone, chlorine, chlorine dioxide, heat, ultraviolet (UV) light, and ionizing radiation offer good performance potential for decontamination of rDNA processing wastewater. Treatment processes, such as incineration, heat treatment, gamma and electron radiation, and chemical decontamination, appear to be suitable for treatment of rDNA sludge. Prevention of the release of the microbial agents to air and/or decontamination of the air stream can be effectively achieved by nitration or UV radiation. The decontamination of surfaces may be accomplished by the use of heat, UV radiation, or chemicals such as glutaraldehyde, formaldehyde, ethylene oxide, and alcohols.
