In this Phase II project, Edenspace Systems Corporation seeks to demonstrate the use of transgenic plants that exude significant amounts of a rapidly biodegradable chelator-citric acid-from their roots, enabling a cost savings of more than 70 percent in lead phytoextraction. A citrate synthase (CS) transgene was placed under the control of different plant promoters to overexpress the gene in roots ...

New environmental regulations have identified many of the currently used oxidizing agents employed for industrial waste control, disinfection, and wastewater treatment as a caveat that must be addressed. Ferrate has potential for becoming the alternative of choice because of its aggressive oxidation properties and its negligible impact on the environment. However, there has been little industrial ...

Rapid, handheld, or portable instrumentation for determining the quality of natural waters, recreational waters, and distributed and treated supplies does not currently exist. Echo Technologies, Inc., completed a Phase I project that demonstrated a new approach for the identification of bacteria in aqueous systems. The approach uses bacteriophage as the molecular recognition element. Bacteriophage ...

Most buses, heavy-duty fleet vehicles, and construction and farm machinery are equipped with diesel engines. The diesel engine is an energy-efficient machine, but its exhaust emissions present a serious health and environmental problem. Drastic reductions in exhaust soot have been mandated throughout the world, including the recent U.S. Environmental Protection Agency (EPA) mandate to reduce smog- ...

THE TECHNICAL OBJECTIVES OF THIS PROPOSAL ARE ORIENTED TOWARD THE DEVELOPMENT OF SOIL SURFACTANT FLUSHING AND WASHING AS A LOW-COST, LOW-IMPACT, LOW-RISK, EFFECTIVE TECHNIQUE FOR THE REMOVAL AND ULTIMATE DESTRUCTION OF THE ORGANIC CONTAMINANTS IN SOIL. THESE OBJECTIVES ARE: DEMONSTRATION OF THE EFFECTIVENESS OF AN IONIC SURFACTANT SOLUTION AT CONCENTRATIONS ABOVE THE CRITICAL MICELLE CONCENTRATION ...

Improving corrosion control is a significant technical challenge that must be addressed before lightweight metal alloys of aluminum and magnesium can be more widely used in manufacturing industries such as automobile, aerospace, and metal finishing. Use of lightweight metal alloys would provide many advantages for these industries. For example, a 40 percent reduction in the weight of an automobile ...

Dynaflow, Inc., proposes the development of a novel jet-induced cavitation process for the removal of various pollutants¿including pesticides from wastewater discharge¿ that would be economical, readily applicable to both large- and small-scale systems, and that does not produce potentially hazardous by-products of chlorination and ozonation. Ultrasonically induced cavitation is known to be capa ...

The goal of this project is to develop a portable system for the real-time detection and quantification of adenovirus in wastewater. The system is based on a small, portable flow cytometer that was developed and is being marketed by Becton Dickinson Biosciences (BDB) under the trade name FACSCount¿ for use in selected medical and research applications. Unlike previous efforts to apply flow cytome ...

A novel, environmentally benign antimicrobial surface modification based on immobilized quaternary ammonium-functionalized dendrimers is proposed for the prevention of biofilm formation. Dendrimers are unique nanomaterials that have attracted attention as possible antimicrobial agents due to their compact structure, high local charge density of functional surface groups, unique carrier properties, ...
