Abstract: The present invention relates to a reclamation and recycling process for graphene oxide, a scaffold comprising graphene oxide, a modular graphene oxide-based microbial fluid filter and a filter tool that allows the correct compression pressure of a modular filtration cartridge, and prevents internal leakage along the internal wall of the filter and thus provides correct sealing of the filter. Such modular graphene oxide-based microbial fluid filter does not require a sub-micrometer pore filtering medium, yet has a microbial filtration efficiency of up to 99.99% and the ability to filter particulates while still providing the filtration flow rates of current filters that do not employ a sub-micrometer pore filtering medium.

Abstract: A method for preventing biodeterioration of fuel. The method reduces the microbial growth in fuel by administering an antimicrobial peptide (or efflux pump inhibitor) to a fuel phase of the fuel, an aqueous phase of the fuel, or both, which disrupts the cellular membrane (or the efflux pumps thereof) of microbes comprising the growth.

Abstract: The invention provides a system of heavy metal sequestration by bacteria. The bacteria expresses the ppk, mt, and/or ?-galactosidase (lacZ) genes and can tolerate at least 25 ?M mercury, 1,000 ?M zinc, 250 ?M cadmium, and 3,000 ?M Pb. The system allows for facile determination of the presence of heavy metal contaminants in a liquid and the facile collection of the bacteria that has sequestered large amounts of heavy metal. Further provided is a system of gene expression in bacteria that comprises phage and plastid gene expression elements and delivers a particularly high level of protein expression and heavy metal resistance.

Abstract: A system and device for filtering fluids using graphene oxide (GO) is provided. GO-based filters may be used for the efficient removal of microorganisms from organic and aqueous liquids and may be used to prevent fuel biodeterioration. Functionalization of graphene oxide with reactive oxygen functional groups provides physical properties to the GO including high solubility in polar solvents, good colloidal properties, low production costs, low toxicity, and a large surface area which can be decorated with antimicrobial agents including nanosilver. GO may be used as a filtration media for efficient removal of bacteria and to remove small amounts of water from hydrocarbon fuels. The GO filter media may be made of a plurality of GO particles, a structural core coated with GO, a non-porous structural membrane coated with GO, or a filtering membrane coated with GO. A method for sampling impurities found in an environmental sample is also provided.
