Abstract:
Thermophilic gram-positive anaerobic host cells, for example Themoanaerobacterium sachharolyticum ("T sacch"), express heterologous biomass degrading enzymes, such as cellulases, and are able to produce useful fermentation products from cellulose. Useful fermentation products include, for example, ethanol, acetic acid, lactic acid or CO2. In order to provide maximum expression and activity levels, biomass degrading enzymes can be expressed from codon-optimized nucleotide sequences, can be expressed under the control of a high-efficiency promoter, and/or can be fused to a signal peptide. In addition, the host cell, for example, a T sacch host cell, can be genetically altered to further improve ethanol production, for example by disrupting the production of organic products other than ethanol.
Abstract:
The invention relates to the discovery that the Claudin-1 protein functions as a co-receptor for entry of HCV into cells. Methods of inhibiting, preventing or mitigating HCV infections by inhibiting HCV interactions with Claudin-1 are provided. Methods of identifying agents or compounds that interfere with HCV interactions with Claudin-1 are also provided. Finally, useful kits, cell culture compositions, agents, and compounds related to the inhibition of HCV interactions with Claudin-1 are also disclosed.
Abstract:
HCV variants are described. The variants include polynucleotides comprising non-naturally occurring HCV sequences and HCV variants that have a transfection efficiency and ability to survive subpassage greater than HCV that have wild-type polyprotein coding regions. Expression vectors comprising the above polynucleotides and HCV variants are also described, as are the provision of cells and host cells comprising the expression vectors. Methods for identifying a cell line that is permissive for infection with HCV are also provided, as are vaccines comprising the above polynucleotides in a pharmaceutically acceptable carrier. Additionally, methods for inducing immunoprotection to HCV in a primate are described, as are methods for testing a compound for inhibiting HCV replication.

Abstract:
The present invention is directed to a. yeast strain, or strains, secreting a full suite, or any subset of that, full suite, of enzymes to hydrolyze com starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicelhiiose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction. The resulting strain, or strains, can be further used to reduce the amount of external enzyme needed to hydrolyze a biomass feedstock during an Simultaneous Saccharification and Fermentation (SSF) process, or to increase the yield of ethanol during SSF at current saccharolytic enzyme loadings. In addition, multiple enzymes of the present invention can be co-expressed in cells of the invention to provide synergistic digestive action on biomass feedstock. In some aspects, host cells expressing different heterologous saccharolytic enzymes can also be co-cultured togetherand used to produce ethanol from biomass feedstock.

Abstract:
The present invention relates to a method of increasing the milk and/or meat quantity of silage-fed animals comprising the steps: a) treating plants and/or propagules and/or sites where the plants are growing or are to grow with at least one strobilurin compound b) producing silage from the plants treated according to step a) c) feeding the milk and/or meat producing animals with the silage produced according to step b) made from the plants treated according to step a). Furthermore, the present invention relates to silage for feeding animals, produced from plants treated with at least one strobilurin compound prior to producing said silage. In addition, the present invention relates to the use of at least one strobilurin compound to increase the milk quantity of silage-fed milk-producing animals. Moreover, the present invention relates to the use of at least one strobilurin compound to increase the meat quantity of silage-fed meat-producing animals.
