  • Publication number: 20240075408
    Abstract: Methods and systems for the detection and quantification of multiplicity of ionic analytes comprising bromide, phosphate, sulfite, thiosulfate, thiocyanate, and formate, and optionally fluoride, chloride, chromate, selenate, perchlorate, nitrate, nitrite, and sulfate, using ion chromatography and suppressed ion conductivity. The method comprises loading a sample loop with a sample; injecting the sample from the sample loop into a column with an eluent, wherein the column comprises a guard column and an analytical column; separating, with the column, the injected sample at an effective separation temperature the injected sample in the presence of an organic modifier into a multiplicity of detectable ionic analytes; suppressing, with a suppressor, background signal; and detecting, with a detector, the multiplicity of ionic analytes.

  • Publication number: 20230264991
    Abstract: The present invention is directed to systems and methods for removing trichloroethane (TCA), trichloroethene (TCE), and 1,4-dioxane (1,4-D) from contaminated water and wastewater. The system and methods relying on catalyst reduction of TCA and TCE, and the reduced products are degraded by microorganisms that are capable of biodegrading ethane and 1,4-D. In certain embodiments, a catalyst film comprises precious nanoparticles with diameters of 5-40 nm and a biofilm comprising microorganisms that are capable of degrading ethane and 1,4-D are used in a dual-reactor system to remove TCA, TCE, and 1,4-D from contaminated water and wastewater.

  • Publication number: 20230220494
    Abstract: The present disclosure provides for characterization of normal flora and identifying biomarkers in the gut of healthy, neurotypical subjects. Aspect of the disclosure provide for the characterization of the gut microbiome in ADS subjects, characterized by reduced richness and significant loss of the ‘Prevotella-like enterotype’ compared to neurotypical subjects. The relative abundance of genera Prevotella, Coprococcus, Prevotellaceae and Veillonellaceae are significantly lower in autistic children than in neurotypical children. Further, Prevotella, is one of the three main classifiers for the human enterotypes, along with Bacteroides and Ruminococcus. These three core genera are among main contributors in the principle component analysis. ‘Prevotella-like enterotype’ was absent in the autistic group, while neurotypical samples showed an even distribution among the three enterotypes.

  • Patent number: 10435659
    Abstract: A membrane biofilm reactor including a vessel defining a volume is disclosed. The reactor also typically includes a first and second plurality of hollow fiber membranes. Each hollow fiber membrane generally has an outer surface and a lumen, and is located within the volume. The reactor further preferably includes a first and second gas feedstock. The first gas feedstock is provided through a first inlet in fluid communication with the lumens of the first plurality of hollow fiber membranes. The second gas feedstock is provided through a second inlet in fluid communication with the lumens of the second plurality hollow fiber membranes. Finally, the reactor also typically includes a biofilm formed on the outer surface of the hollow fiber membranes and made up of methanotrophs, Methanosarcina acetivorans, or both. The first gas feedstock is preferably different from the second gas feedstock.
