Patent number: 7682815Abstract: The invention disclosure is a method of bioremediation of wastewater, particularly groundwater, by utilizing coupled anaerobic and aerobic biological treatment, more specifically, methanogenic (strictly anaerobic) and methanotrophic (strictly aerobic) microbial populations, in combination with a supply of in-situ generated water-dissolved oxygen and hydrogen. Water electrolysis is used to produce water-dissolved oxygen and hydrogen. The immediate advantage of using H2 from the electrolysis is to provide electron donors to methanogens to reductively dechlorinate the chloroaliphatics, and to reduce the water carbonates and generate methane which is used as energy and carbon source for the methanotrophic bacteria. Oxygen is used as electron acceptor by the aerobic bacteria, including the methanotrophs. The addition of an organic carbon source can be minimized or even eliminated, so as to diminish the competition between methanotrophic bacteria and heterotrophic bacteria for oxygen.Type: GrantFiled: May 25, 2005Date of Patent: March 23, 2010Assignee: National Research Council of CanadaInventors: Serge R.

The waste is delivered through a rotating organic material digester in a controlled manner for converting the organic waste material content of the raw waste to a bio-fuel. Treated material discharged from the digester is passed through a screen to remove any inorganic materials, leaving the bio-fuel. The bio-fuel is dried at a drying station and then delivered to a boiler for combustion to generate energy.Type: ApplicationFiled: November 2, 2005Publication date: March 4, 2010Inventor: Pearse O'Kane

Patent number: 7658850Abstract: The present invention provides a mixed bacterial culture, designated as the culture Atz Mix 1, which degrades atrazine at various temperatures (10° C. to 30° C.) in a wide range of atrazine concentrations (several ppb to ten thousand ppm), without formation of toxic metabolites. Atz Mix 1 is a stable mixed culture and includes catabolic genes trzN, atzB, atzC coding the enzymes for the degradation of atrazine to cyanuric acid, and the gene trzD coding the enzymes for subsequent opening of s-triazine ring. The invention further includes a microbiological method of degrading atrazine and other s-triazine compounds for remediation of atrazine-contaminated soils, even those rich in nitrogen, as well as for accelerating the process of atrazine mineralization in waste waters containing high concentrations of s-triazine compounds.Type: GrantFiled: August 20, 2008Date of Patent: February 9, 2010Assignee: Rudjer Boskovic InstituteInventors: Dubravka Hrsak, Maja Havriluk

Publication number: 20100028485Abstract: The invention relates to strains of Talaromyces emersonii which are thermostable and encode thermostable enzymes. The enzymes retain activity at temperatures above 550 C. These strains and enzymes find use in a variety of processes from waste reduction to the production of novel food ingredients and the production of bio-fuels.Type: ApplicationFiled: February 9, 2007Publication date: February 4, 2010Inventors: Maria Gerardine Tuohy, Patrick Gerard Murray, Teresa Caroline Gilleran, Catherine Majella Collins, Francis Jeremiah Reen, Lassarina Patrick McLoughlin, Anne Geraldine Stephanie Lydon, Alan Patrick Maloney, Mary Noelle Heneghan, Anthony John O'Donoghue, Cathal Sean Mahon
