  • Patent number: 11972882
    Abstract: A power cable or a hybrid power-data cable includes power conductors and a plurality of continuity wires positioned radially outside of the power conductors. The continuity wires are positioned relative to the power conductors such that a cut in the cable will sever one of the plurality of continuity wires before a cut into the power conductors can occur.

  • Patent number: 9102989
    Abstract: Genetically modified strains of C. tropicalis, which will not revert to wild-type activity at the POX 4 and/or POX 5 locus, are disclosed. The strains are ?-oxidation blocked and have been transformed through homologous recombination with a construct which deletes a portion of the POX 4 and/or POX 5 gene. The modified strains may be used to increase yields of dicarboxylic acids produced in host cells of the strains. Methods for blocking the ?-oxidation pathway in a C. tropicalis host cell are also provided.

  • Patent number: 7388084
    Abstract: The present invention provides modified promoters from Candida troplicalis CYP and POX4 genes. The modified promoters have various sequence motifs added, deleted, or altered in order to modulate expression of a coding sequence operably linked thereto. The sequence motifs comprise repressors of gene induction (URS sequences) and activators of gene induction (UAS sequences) as well as oleic acid response elements (ORE sequences). Yeast host cells comprising such modified promoters are also provided. Methods of altering expression of a protein of the beta or omega oxidation pathways using a subject modified promoter are also provided.

  • Publication number: 20040265980
    Abstract: The present invention provides methods of converting or increasing conversion of a fatty acid to its corresponding dicarboxylic acid. The methods comprise isolating a promoter from a yeast gene which gene is induced when the yeast is grown on a fatty acid or alkane substrate, and operably linking the promoter to a gene involved in dicarboxylic acid production to form an expression vector. Yeast cells are subsequently transformed with such an expression vector and cultured in a media containing an organic substrate biooxidizable to a mono- or polycarboxylic acid, and resultant yeast cells convert or increase conversion of fatty acids to their corresponding dicarboxylic acids. Examples of promoters that may be used in the methods of the present invention include those from C. tropicalis catalase, citrate synthase, 3-ketoacyl-CoA thiolase A, citrate synthase, O-acetylhomserine sulphydrylase, protease, carnitine O-acetyltransferase, hydratase-dehydrogenase, and epimerase genes.
