  • Patent number: 11758931
    Abstract: The present disclosure provides methods and compositions useful for the production of slaughter-free meat products, and the characterizations of the same. The slaughter-free meat products contain several points of distinction when compared to conventional meat procured by harvesting the tissue of a dead animal. Such points of distinction include, but are not limited to, significantly reduced or substantially no: steroid hormones, antibiotics, or microbial contamination; lower fat content; no vasculature; and extended shelf life both at room temperature and when refrigerated.

  • Patent number: 6943006
    Abstract: A method for selective cleavage of C—N bonds genes that encode for at least one enzyme suitable for conversion of carbazole to 2-aminobiphenyl-2,3-diol are combined with a gene encoding an amidase suitable for selectively cleaving a C—N bond in 2-aminobiphenyl-2,3-diol, forming an operon that encodes for cleavage of both C—N bonds of said carbazole. The operon is inserted into a host culture which, in turn, is contacted with the carbazole, resulting in selective cleavage of both C—N bonds of the carbazole. Also disclosed is a new microorganism that expresses a carbazole degradation trait constitutively and a method for degrading carbazole employing this microorganism.

  • Patent number: 6861258
    Abstract: A method for introducing and stabilizing heterologous and recombinant genes in a thermophilic host in which a characteristic gene defining a detectable host characteristic is inactivated or deleted from the thermophilic host, resulting in a modified thermophilic host expressing an absence of the detectable host characteristic. A DNA fragment of interest is inserted into the modified thermophilic host together with an intact characteristic gene, whereby the detectable host characteristic is restored to the thermophilic host, thereby enabling detection and confirmation of successful transformation using plasmid vectors and integration of the DNA fragment into the chromosome of the thermophilic host.

  • Publication number: 20030175854
    Abstract: A method for producing beta-carotene and carotene-related pigments in which a plurality of thermophilic microorganisms is collected and screened for the production of pigments. Those pigment-producing thermophilic microorganisms having yellow, red or orange coloration are identified and separated from the collection of thermophilic microorganisms. Thereafter, the selected pigment-producing thermophilic microorganisms are mutated by non-recombinant means to enhance pigment production, forming a mutant pigment-producing thermophilic microorganism. In accordance with one embodiment of this invention, a gene of interest suitable for producing a protein of interest is introduced into the mutant pigment-producing thermophilic microorganism, resulting in over-production of the carotene pigment and the protein of interest. Also disclosed are suitable plasmids and expression vectors suitable for use in the method of this invention.
