  • Patent number: 10619458
    Abstract: A computer supported method, computer system and computer program product for exploring and producing a subsurface heterogeneous hydrocarbon source and generating a predictive production map of an area under investigation, based on microbial prospecting. Microbial data representative of microbial activity attributable to hydrocarbon microseepage and hydrocarbon productivity data of a plurality of geographic locations are retrieved and correlated by the computer in a data correlation algorithm, providing a threshold hydrocarbon productivity quantity and a truncated set of the retrieved microbial data. The set identifies individual types of the microorganisms and corresponding individual weighting factors computed by the data correlation algorithm, for distinguishing prospective hydrocarbon productivity quantities from non-prospective hydrocarbon productivity quantities.

  • Patent number: 6727072
    Abstract: A kit containing the reagents necessary for the qualitative or quantitative demonstration of epidermal growth factor receptor (EGFR) in formalin-fixed, paraffin-embedded tissue sections. A immunohistochemical staining procedure is employed which utilizes a primary monoclonal mouse antibody that selectively binds to EGFR. The primary antibodies bound to tissue antigens are detected using a peroxidase labeled polymer that is conjugated with secondary anti-mouse immunoglobulin antibodies. The enzymatic conversion of the subsequently applied chromogen results in formation of a visible reaction product at the site of the EGFR antigen. Following development of the chromogen, specimens may then be counterstained and coverslipped. Results are interpreted using a light microscope or other optical imaging device. The detection system is adapted for both manual and automated staining.

  • Patent number: 5326703
    Abstract: A method and system for enhancing the motility of microorganisms by placing an effective amount of chlorinated hydrocarbons, preferably chlorinated alkenes, and most preferably trichloroethylene in spaced relation to the microbes so that the surprisingly strong, monomodal, chemotactic response of the chlorinated hydrocarbon on subsurface microbes can draw the microbes away from or towards and into a substance, as desired. In remediation of groundwater pollution, for example, TCE can be injected into the plume to increase the population of microbes at the plume whereby the plume can be more quickly degraded. A TCE-degrading microbe, such as Welchia alkenophilia, can be used to degrade the TCE following the degradation of the original pollutant.

These bed-forming materials may be preloaded with organic carbon materials to provide a nutrient source for the microogranisms. The biological reactor may continuously treat effluent from, for example, an industrial plant, in either a batch or continuous process. A water solids removal subsystem may be positioned upstream of the biological reactor to remove organic carbon compounds and various solids from the contaminated water prior to treatment. Optional bed cleaning mechanisms may also be included in the biological reactor.
