    Abstract: Genetic fusions for use in genetic engineering of eukaryotic algae employ a promoter from a light harvesting protein fused to a protein of interest. The fusions can be introduced and selected using an antibiotic resistance determinant. One gene useful for such selection is the sh ble gene encoding a bleomycin binding protein.

    Abstract: 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.

    Abstract: The disclosure relates to novel microencapsulation processes based on the use of high viscosity fluids (e.g., gelatinized starch and alginate), which are mixed and then sprayed using a much gentler hydraulic pressure and, preferably gas-based atomization into a crosslinking solution (e.g. of calcium chloride). To improve the efficiency of the system, the process can be performed in a continuous mode rather than by a conventional batch process. This involves continuous or intermittent harvest of the microparticles collected in the capture vessel followed by amendment and recycling of the CaCl2 solution and its redeployment into the capture vessel. The process allows production of microencapsulated probiotic bacteria without major losses in viability, thereby providing a useful and efficient new manufacturing method for the stabilization of probiotic bacteria prior to their introduction into functional foods.

    Abstract: A microbial biomass, made from algae, bacteria, fungi, yeast, or combinations thereof, provides a feed for animals raised either in agriculture or aquaculture. A feed additive, and a therapeutic composition can also be made from a microbial biomass of algae, bacteria, fungi, yeast, or combinations thereof. The feed, feed additive, and therapeutic composition can comprise one or more proteins, peptides, antibodies, antibody fragments, or a combination thereof, wherein said proteins, peptides, antibodies, antibody fragments, or a combination thereof are non-native to the microbes of the biomass. The biomass can have therapeutic, bioactive, nutritional, and/or immunogenic properties.
