20120237938 | METHODS FOR IMPROVED DNA RELEASE FROM BINDING SUBSTRATES AND/OR DECREASING PCR INHIBITION IN PATHOGEN DETECTION - Disclosed herein are processes for collecting nucleic acids from particulate samples. One embodiment disclosed herein relates to the use of ultrasonic energy to simultaneously shear large nucleic acid molecules and large particulates to very small sizes prior to or during a chemical binding step to a nucleic acid binding surface. Another embodiment involves crushing the nucleic acid binding surface prior to eluting the bound nucleic acid molecules to enable better wetting of the nucleic acid binding surface and easier diffusion of bound nucleic acid molecules out of the nucleic acid binding surface. | 09-20-2012 |

20120273189 | PREVENTION OF BIOMASS AGGREGATION AT INJECTION WELLS - Disclosed herein is introduction of different nutrient solution formulations to a subterranean target site to prevent biofilm formation and biomass aggregation at the sand face of an injection well bore during MEOR or bioremediation processes. A first nutrient solution formulation supports growth of introduced microorganisms and a second nutrient solution formulation is used to promote biofilm formation to allow plugging of pores and channels in the subterranean target site, for MEOR or bioremediation. | 11-01-2012 |
20120292022 | COMPOSITION FOR IMPROVING OIL RECOVERY INCLUDING N-LAUROYL AMINO ACID-BASED COMPOUNDS AND MICROBES - Chemical compounds that are N-lauroyl amino acids or derivatives thereof were found to have oil-releasing activity. Solutions containing these compounds and microorganisms having oil release and/or plugging biofilm formation properties may be introduced into oil reservoirs to improve oil recovery. | 11-22-2012 |
20120295823 | OIL RELEASE WITH N-LAUROYL AMINO ACID-BASED COMPOUNDS - Chemical compounds that are N-lauroyl amino acids or derivatives thereof were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal. | 11-22-2012 |
20130000912 | ALTERING THE INTERFACE OF HYDROCARBON-COATED SURFACES - Methods and compositions are provided wherein microorganisms are used to alter the interface of hydrocarbons and hydrocarbon-coated surfaces to increase oil recovery, for improved bioremediation and/or to benefit pipeline maintenance. | 01-03-2013 |
20130079259 | OIL RELEASE WITH POLYETHYLENE OXIDE SEGMENT-CONTAINING N-LAUROYL AMINO ACID-BASED COMPOUNDS - Chemical compounds that are N-lauroyl amino acids containing a polyethylene oxide segment were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal. | 03-28-2013 |
20130095562 | OIL RELEASE WITH AMINO ACID-BASED COMPOUNDS HAVING A LONG CHAIN N-ACYL GROUP - Chemical compounds that are N-acyl amino acids or derivatives thereof having long chain N-acyl groups were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal. | 04-18-2013 |
20140018529 | NUCLEIC ACID ISOLATION AND PURIFICATION SYSTEM - A device was developed for use in nucleic acid isolation that includes reversibly connected upper and lower chambers, and contains a fibrous nucleic acid binding surface which can expand in the chambers when wetted. The device may be used in a rapid nucleic acid isolation process without clogging while accommodating complex samples. | 01-16-2014 |
20140116706 | ALTERING THE INTERFACE OF HYDROCARBON-COATED SURFACES - Methods and compositions are provided wherein microorganisms are used to alter the interface of hydrocarbons and hydrocarbon-coated surfaces to increase oil recovery, for improved bioremediation and/or pipeline maintenance. | 05-01-2014 |
