    Abstract: A biodegradable hydrogel has been made based on high concentrations of whey protein isolate (WPI). WPI gels of different compositions were fabricated by thermally inducing gelation of high-concentration suspensions of protein, and characterized for compressive strength and modulus, hydration swelling and drying properties, mechanical behavior change due to polysaccharide additives, and intrinsic pore network structure. The gels were shown to be compatible with bone cells and could be used as bone tissue scaffolds. In addition, WPI fibers were produced by electrospinning. Several additives could be incorporated into the WPI gels, including structural additives, growth factors, amino acids, etc. The WPI hydrogels can be made with glycerol to increase flexibility and stability.

    Abstract: A method of tracking cell identity across analytical platforms uses stochastic barcoding (SB). SB uses a randomly generated code based on one or more of the number, color and position of beads encapsulated together with a set of cells of interest. SB use is demonstrated in an application where cells are transferred from a microwell array into a microtiter plate while keeping their identity, and obtained an average identification accuracy of 96% for transfer of 100 blocks. Model scaling of the method up to 1000 blocks demonstrated that SB is able to achieve approximately 90% accuracy.

    Abstract: The composite material is comprised of a substrate of discrete particles and a network of interconnected mycelia cells bonding the discrete particles together. The mycelia cells are selected from the group consisting of at least one of Agrocybe brasiliensi, Flammulina velutipes, Hypholomoa capnoides, Hypholoma sublaterium, Morchella angusticeps, Macrolepiota procera and Coprinus comatus. The fungus digests the nutrient material over a period of time sufficient to grow hyphae and to allow the hyphae to form a network of interconnected mycelia cells through and around the discrete particles thereby bonding the discrete particles together to form a self-supporting composite material.

  • Publication number: 20150093478
    Abstract: An absorbent pad that contains activated carbon to reduce confinement odor in a vacuum-packaged food product is provided. An embodiment of absorbent pad contains activated carbon and an antimicrobial agent that further reduces confinement odor by two mechanisms of action: reducing bacterial counts in the liquid purge that cause breakdown of carbohydrates and proteins in food products; and trapping of confinement odor-causing breakdown products by the activated carbon. The absorbent body in the absorbent pad actively draws in liquid purge and dissolved volatile breakdown products in the vacuum package that produce confinement odor, which produces greater and more rapid contact of odor-causing compounds with the activated carbon.

  • Patent number: 8992845
    Abstract: A method for separating CO2 from gas mixtures uses a slurried media impregnated with buffer compounds and coating the solid media with a catalyst or enzyme that promotes the transformation of CO2 to carbonic acid. Buffer sorbent pebbles with a catalyst or enzyme coating are provided for rapid separation of CO2 from gas mixtures.

  • Patent number: 8993255
    Abstract: The present invention provides: a protein having a fructosyl amino acid oxidase activity which protein is useful for measurement of a glycosylated protein (particularly, glycosylated hemoglobin); a modified protein thereof; and use of the protein or the modified protein. The protein of the present invention is, for example, a fructosyl valyl histidine oxidase derived from Phaeosphaeria nodorum, the fructosyl valyl histidine oxidase having excellent thermal stability and substrate specificity and also having a small Km value to fructosyl valyl histidine. This allows a glycosylated protein measuring reagent to be stored in a long time and measurement accuracy of the glycosylated protein measuring reagent to be improved.

  • Patent number: 8986962
    Abstract: This invention provides co-cultures of photosynthetic microorganisms and biofuel producing microorganisms. In certain embodiments, polysaccharide-producing, photosynthetic microorganisms are microalgae having frustules provide a substrate on which biofuel-producing microorganisms can grow. In other embodiments, the photosynthetic microorganisms produce a lipid and the non-photosynthetic microorganisms produce a solvent in which the lipid is soluble.

  • Patent number: 8986966
    Abstract: The invention features methods for separating cells from a sample (e.g., separating fetal red blood cells from maternal blood). The method begins with the introduction of a sample including cells into one or more microfluidic channels. In one embodiment, the device includes at least two processing steps. For example, a mixture of cells is introduced into a microfluidic channel that selectively allows the passage of a desired type of cell, and the population of cells enriched in the desired type is then introduced into a second microfluidic channel that allows the passage of the desired cell to produce a population of cells further enriched in the desired type. The selection of cells is based on a property of the cells in the mixture, for example, size, shape, deformability, surface characteristics (e.g., cell surface receptors or antigens and membrane permeability), or intracellular properties (e.g., expression of a particular enzyme).

  • Publication number: 20150072383
    Abstract: The present disclosure provides engineered transaminase polypeptides for the production of amines, polynucleotides encoding the engineered transaminases, host cells capable of expressing the engineered transaminases, and methods of using the engineered transaminases to prepare compounds useful in the production of active pharmaceutical agents. The present disclosure provides engineered polypeptides having transaminase activity, polynucleotides encoding the polypeptides, methods of the making the polypeptides, and methods of using the polypeptides for the biocatalytic conversion of ketone substrates to amine products. The present enzymes have been engineered to have one or more residue differences as compared to the amino acid sequence of the naturally occurring transaminase of Vibrio fluvialis. In particular, the transaminases of the present disclosure have been engineered for efficient formation of chiral tryptamine derivatives from its corresponding prochiral ketone substrates.
