  • Patent number: 12103222
    Abstract: A drawn fused filament fabrication method of three-dimensional printing is disclosed in which the filament extruded is variable and not restricted to the diameter of the nozzle used for extrusion. This method composes three steps. The first is to extrude a small amount of material at a starting position. Next, the extruding head pulls the extruded material along while moving away from the starting position. During this time to material cools down and solidifies. As a result, a thin filament is formed. Third, once the extruding head moves to a destination, a small amount of material can be extruded and deposited to anchor this newly formed filament to a surface. The drawn fused filament fabrication method may be used to print three-dimensional parts having significant lower thickness than the diameter of the nozzle used to extrude the printing material.

  • Patent number: 11401498
    Abstract: Herein a Bacillus exosporium antigen delivery (BEAD) system that provides a means to introduce recombinant proteins or small molecules into the exosporium of members of the B. cereus family of bacteria, i.e. B. anthracis, B. cereus, and B. thuringiensis, is disclosed. The system results in the surface display of recombinant proteins or small molecules such that they can stimulate an immune response. In addition, methods of making and using the system are described.

  • Patent number: 10081790
    Abstract: Herein a Bacillus exosporium molecule delivery (BEMD) system that provides a means to deliver molecules of interest (MOIs) to an environment is disclosed. The system results in the display of MOIs on the exosporium surface of Bacillus family members such that they can be delivered to an environment in a stable and active form. In addition, methods of making and using the system are described.

  • Publication number: 20090117142
    Abstract: The F. necrophorum gene expressing leukotoxin was sequenced and cloned. The leukotoxin open reading frame (lktA) is part of a multi-gene operon containing 9,726 bp, and encoding a protein containing 3,241 amino acids with an overall molecular weight of 335,956 daltons. The protein encoded by the gene was truncated into five polypeptides having overlapping regions by truncating the full length gene into five different sections and amplifying, expressing, and recovering the protein encoded by each of these sections. Additionally, a region upstream of the gene was sequenced and the polypeptide encoded by that nucleotide sequence was purified and isolated. These polypeptides along with the full length protein are then tested to determine their immunogenicity and protective immunity in comparison to the efficacy of immunization conferred by inactivated native leukotoxin in F. necrophorum culture supernatant.
