Abstract: This invention relates to compositions and methods for the production of Type III polyketides using genetically modified oleaginous yeast strains, for example, Yarrowia lipolytica.

Abstract: This disclosure provides new filtration systems, filtration media, and processes for removing per- and polyfluoroalkyl substances (PFAS) from PFAS-contaminated water. The filtration systems, filtration media, and processes use a combination an activated carbon and a calcium sulfate which are mixed and immobilized or contained within a filter component such as a filter housing which provides a flow path for the contaminated water. This combination of components can remove PFAS contaminants to concentrations below the level of detection and provides other unexpected benefits as disclosed herein.

Abstract: This disclosure relates to new filtration systems, granular substrates, granular media and processes that are highly effective for removing suspended oil, particulates and oily particulates from an oil-water mixture. The new filtration media comprises a microporous granular substrate having a combination of specified micro-porosity, hardness and additional characteristics, the substrate being modified by an infused or coated absorption composition. This resulting filtration media displays excellent filtration performance, including outstanding durability and robustness to sustain its excellent performance over a large number of backwash cycles.

Abstract: This disclosure relates to filtration screens for use in a backwashable granular media bed filtration system. Drop-in retrofit kits for a backwashable granular media bed filtration system comprising one or more filtrations screens are provided herein. Such screens and kits can comprise a media support screen, a backwash filter screen, or a combination thereof. The kit can further comprise an agitator element comprising an impeller having vanes in which the impeller vane surfaces are coated with an abrasion resistant material. Associated filtration systems and processes are also described herein.

Abstract: The present invention relates to a composition comprising a 3D printed hydrogel, wherein at least two different populations of cells are embedded in the 3D printed hydrogel. The different populations of cells can produce one or more products. The 3D printed hydrogel can be lyophilized and rehydrated, and the cells can continue to produce the product. Also disclosed are methods of producing a product, and methods of producing a 3D printed hydrogel comprising different populations of cells.

Abstract: Genetically engineered oleaginous fungi (e.g., engineered Yarrowia lipolytica) are provided for use in itaconic acid production. In some aspects, the engineered fungi comprise a transgene for expression of a cis-aconitic acid decarboxylase (CAD) enzyme and, optionally, one or more further genetic modifications. Methods and culture systems for production of itaconic acid using such fungi are also provided.

Abstract: A visual indicator device and method for determining the presence of oily contaminants in an aqueous stream are provided. The device includes a filtration status chamber for receiving and discharging the aqueous stream, and a transparent wall enabling viewing of the chamber interior. A fluid-pervious filtration media within the chamber is infused with an absorption composition at which the contaminant on contact with the media is immobilized. The media has a surface viewable through a transparent wall of the filtration status chamber, and the stream flow path causes the stream to impinge at the media via the surface, whereby the contaminants collect selectively at the media surface and are highly visible through the transparent wall.

Abstract: A visual indicator device and method for determining the presence of oily contaminants in a gaseous stream are provided. The device includes a filtration status chamber for receiving and discharging the gaseous stream, and a transparent wall enabling viewing of the chamber interior. A fluid-pervious filtration media within the chamber is infused with an absorption composition at which the contaminant on contact with the media is immobilized. The media has a surface viewable through a transparent wall of the filtration status chamber, and the stream flow path is such as to cause the stream to impinge at the media via the said surface, whereby the contaminants collect selectively at the media surface and are therefore highly visible through the transparent wall.

Abstract: A method and apparatus are provided for separating droplets of finely aerosolized elemental mercury from a fluid stream in which the droplets are dispersed, particularly a gaseous stream. In the method, a precious metal wire capillary surface or precious metal-coated wire capillary surface is contacted with the gaseous stream, causing the aerosolized droplets to deposit on the capillary surface and by capillary action to coalesce with other of such droplets. The surface is oriented to allow the mercury to flow by gravitational forces and capillary action to the lowermost portions of the surface, where it accumulates and can be collected. Metallic capillary surfaces comprised of finely braided strands of silver, gold, palladium, platinum, or rhodium wire, or wire coated with one or more of these metals, are particularly preferred.

Abstract: Viscoelastic compositions capable of preventing microbial proliferation and capable of capturing microbial membrane and cell wall decomposition products are provided. The compositions comprise thermal reaction products of blends of fatty acids derived and isolated from drying and semi-drying oils such as linseed, safflower, and tung oil, with a polymer component such as for example poly (isobutyl methacrylate). These compositions are capable of capturing microbes and controlling their proliferation at a material on which the compositions are deposited, and further capable of absorption or incorporation of lipopolysaccharide and protein membrane materials and endotoxins.
