摘要： A crustacean or rotifer is infected with a recombinant infectious virus that expresses a protein exogenous to the virus. The genome of the crustacean or rotifer itself remains unaltered. Crustacean, rotifer, insect, or viral promoters drive the transcription of a gene inserted into the recombinant virus genome, and the virus replicates in the crustacean or rotifer cell cytoplasm. The infected crustacean or rotifer can be provided directly to humans or non-human animals, or, following production and harvest of the crustaceans or rotifers, purified recombinant protein or polypeptide can be provided. Large quantities of biopharmaceuticals can be produced rapidly and inexpensively using this production system.

摘要： Most microalgae are obligate photoautotrophs and their growth is strictly dependent on the generation of photosynthetically-derived energy. In this study it is shown that the microalga Phaeodaclylurn tricornutum can be engineered to import glucose and grow in the dark through the introduction of genes encoding glucose transporters. Both the human and Chlorella kessleri glucose transporters facilitated the uptake of glucose by P. tricornutum, allowing the cells to metabolize exogenous organic carbon and thrive, independent of light. This is the first successful trophic conversion of an obligate photoautotroph through metabolic engineering, and it demonstrates that methods of cell nourishment can be fundamentally altered with the introduction of a single gene. Since strains transformed with the glucose transport genes are able to grow non-photosynthetically, they can be exploited for the analysis of photosynthetic processes through mutant generation and characterization. Finally, this work also represents critical progress toward large-scale commercial exploitation of obligate phototrophic algae through the use of microbial fermentation technology, eliminating significant limitations resulting from light-dependent growth.

摘要： Recombinant oleaginous alga that include one or more heterologous genes that increase the ability of the alga to use one or more natural saccharides such as cellulosic or hemicellulosic sugars for algal growth are described. The recombinant oleaginous algae are transformed to include one or more genes expressing sugar metabolizing enzymes or sugar transporting proteins, along with suitable control elements. Use of natural saccharides as a carbon source can allow the algae to produce biofuel precursors in a relatively efficient manner. Processes for preparing the alga, growing the alga, and extracting the biofuel precursors from the alga are also described.

摘要： Infectious pancreatic necrosis virus (IPNV), the etiologic agent of infectious pancreatic necrosis in salmonid fish, causes significant losses to the aquaculture industry. The gene for the viral capsid protein (VP2) was cloned into a yeast expression vector and expressed in Saccharomyces cerevisae. Expression of the capsid gene in yeast resulted in formation of approximately 20 nanometer sub-viral particles composed solely of VP2 protein. Anti-IPNV antibodies were detected in rainbow trout vaccinated either by injection of purified VP2-subviral particles (rVP2-SVP) or by feeding recombinant yeast expressing rVP2-SVP. Challenge of rVP2-SVP immunized trout with a heterologous IPNV strain and subsequent viral load determination showed that both injection and orally vaccinated fish had lower IPNV loads than naive or sham-vaccinated fish. This study demonstrates the ability of rVP2-SVPs to induce a specific immune response and the ability of immunized fish to reduce the viral load after an experimentally induced IPNV infection. The invention is not limited to IPNV, and is applicable to other similar viruses for which SVPs can be made and administered to fish.

摘要： Biosecure algae and methods for preparing biosecure algae that have a substantially decreased capability to survive in a natural environment are described. The methods include transforming a genetically modified alga to include an essential gene that is operably linked to a promoter system that is active only in the presence of an inducer compound, transforming the genetically modified alga to include a lethal gene that is operably linked with a promoter system that is inactive only in the presence of a repressor compound. The biosecure algae are only able to survive in an artificial algae culture that includes factors or conditions not found in a natural environment.
