  • Publication number: 20130216653
    Abstract: The present invention relates to the display of bioactive molecules at the surface of spores for both in vitro and in vivo applications. Three small open reading frames (ORFs) have been identified which are very useful for display of bioactive molecules at the spore surface. The encoded small proteins have a molecular weight of less than 12 kDa, which corresponds to about less than 100 amino acids.

  • Patent number: 8329395
    Abstract: The present invention provides a method for producing thiamin products using a microorganism containing a mutation that causes it to overproduce and release thiamin products into the medium. Biologically pure cultures of the microorganisms and isolated polynucleotides containing the mutations are also provided. In addition, methods for detecting a pathogenic microorganism in a clinical sample, assays for identifying an antibiotic, as well as, antibiotics identified by such assays are provided.
