Tersus Environmental enters into patent license agreement with Antea®Group
Nutrisulfate™ “Anaerobic In-Situ bioremediation using the power of metabolic supplements and sulfate reduction technology”
ST. PAUL, MINNESOTA and WAKE FOREST, NORTH CAROLINA, June 26, 2013 -- Antea®Group, a global engineering and environmental consulting firm, and Tersus Environmental announced today the signing of an Exclusive License Agreement for US Patent No. 7138060. Under the terms of the agreement, Tersus Environmental will make, market, promote and sell products for sulfate-enhanced bioremediation of contaminated groundwater. The patent includes a process for using high concentrations of sulfate to stimulate biodegradation of petroleum hydrocarbons (PHCs), other aromatic hydrocarbons and other contaminants susceptible to sulfate-reducing bacteria.
“This license agreement with Antea®Group enables us to further expand our strong foundation of intellectual property,” says Tersus’ Managing Partner, Gary Birk. Our joint resources give Tersus customers the best biotechnology-based solutions to manage complex, challenging environmental liabilities and reduce costs for site closure.”
“We are keen to work with Tersus,” says Mike Martinson, Senior Consultant, Antea®Group. “Tersus’ network of sales associates and staff around the world will help provide a much broader market coverage for our sulfate enhanced technology.”
Enhanced aerobic bioremediation technologies such as the iSOC® gas inFusion technology or the use of oxygen releasing compounds such as TersOx™ are commonly used to accelerate naturally occurring in situ bioremediation of petroleum hydrocarbons, and fuel oxygenates such as MTBE and TBA, by indigenous microorganisms in the subsurface. However, these indigenous microorganisms do not function well in the high contaminant concentrations of the source area. Moreover, the oxygen technologies have to overcome the anaerobic conditions of the source area and often the presence of iron.
Antea®Group developed and proved a sulfate-enhanced in situ remediation strategy to address the anaerobic portion of the plume. Sulfate reduction and methanogenesis appear to dominate natural degradation processes at most sites; and therefore, adding oxygen to the anaerobic portion of the plume may be disadvantageous. The sulfate-enhanced technology, now marketed by Tersus Environmental under the name Nutrisulfate™, stimulates biodegradation by providing a soluble, readily available electron acceptor. In the presence of elevated sulfate, anaerobic groundwater bacteria use BTEX, MTBE and other petroleum hydrocarbons for carbon and energy while mineralizing the hydrocarbons to carbon dioxide and water. Sulfate addition enhances natural conditions and reduces the carbon footprint when compared to conventional remediation. Nutrisulfate™ is a high sulfate metabolic supplement designed to enhance the kinetics and efficiency of microbial systems specifically related to bioremediation. The increase in kinetics and efficiency decreases the remediation time and reduces the amount of substrate / amendment required.
“Deploying Nutrisulfate™ in the anaerobic source zone and one of our oxygen technologies such as iSOC® gas inFusion technology in the perimeter or outskirts of the plume gives Tersus customers the best biotechnology-based solutions to manage complex, challenging environmental liabilities. The use of these two solutions in combination speeds site closure, reduces costs, and leaves the site in an aerobic state precluding the risk of liberating unwanted substances. It’s a game changer,” says Birk.
