    Abstract: An isoform of manganese superoxide dismutase (MnSOD) and polynucleotides encoding it have been identified. This isoform, MnSOD E3(−), is a splice variant lacking exon 3 of the full length MnSOD. The polypeptide can be expressed using appropriate host cells. Modulation of either the expression of the polynucleotides or the activity of the polypeptide is also described. Furthermore, diagnostic and therapeutic methods have been developed as a consequence of the isolation of the polynucleotides and polypeptides.

  • Patent number: 6670152
    Abstract: It is disclosed that the enzymes ATP:corrinoid adenosyltransferase (CobA) from Salmonella typhimurium and reduced flavodoxin (FldA) from E. coli are both necessary and sufficient, in the presence of ATP, to reduce the oxidation state of the cobalt atom in cobalamin and produce adenosylcobalamin. This makes possible the construction of plasmids to confer upon microbial fermentation hosts the ability to synthesize adenosylcobalamin, the supply of which can sometimes be a limitation on microbial growth in fermentation. Since the enzyme flavodoxin reductase (Fpr), also from E. coli, can act to reduce FldA for biological activity, that enzyme should preferably be expressed in a fermentation host as well.

  • Publication number: 20030134822
    Abstract: Mesophilic methane bacteria obtained from digested sludge are acclimatized in an H2/CO2 medium and the acclimatized methane bacteria are grown on a support inclusive of inorganic nutritional salts of trace metal elements by using an immobilized bed bioreactor. The grown bacteria are allowed to metabolize a mixed gas, prepared by adding hydrogen to at least one of coal gas and biogas, into methane and at the same time, cobalamin contained in the fermented liquor is recovered as an extracellular product in the form of cyanocobalamin by using potassium cyanide to thereby produce vitamin B12 efficiently in a high content and high yield.

  • Patent number: 6506570
    Abstract: A method of determining the gender of a bird in ovo comprises detecting the presence or absence of an elevated level of a sex-related hormone in the extra-embryonic fluid of the bird egg, and then determining the gender of the bird within the egg from the presence of an elevated level of a sex-related hormone therein. Preferably, the sex-related hormone is an estrogen. Further preferred are methods in which the extra-embryonic fluid is allantoic fluid. The method is preferably carried out on chicken eggs prior to or during transfer of the eggs from incubator to hatcher.

  • Patent number: 6194224
    Abstract: A diagnostic test strip for determining the presence of a specified analyte in a fluid sample is described. The test strip has a test membrane sandwiched between two layers of a plastic sheath. The upper layer of the sheath has a sample well into which a liquid sample is placed. The test membrane has a sample receiving zone typically containing a buffer and a fatty acid sarcosinate. Adjacent to the sample receiving zone is a reagent zone containing reagent chemicals including gold colloid particles coated with antibodies to the specified analyte. In fluid connection with the reagent zone is a test zone containing immobilized molecules of the specified analyte. Preferably, in fluid connection with the test zone is a control zone containing an indicator that changes color when wetted by the sample and a liquid sink zone to absorb excess liquid in the sample.
