  • Publication number: 20170202940
    Abstract: Delivery systems and methods are provided for delivering a biologically active protein to a host animal. The systems and methods provided include obtaining an algal cell transformed by an expression vector, the expression vector comprising a nucleotide sequence coding for the biologically active protein, operably linked to a promoter. In one illustrated embodiment, the biologically active protein is an antigenic epitope and upon administration to the animal the algal cell induces an immune response in the host animal.

  • Publication number: 20170042187
    Abstract: The present invention is to a safe, biodegradable trace metal binding system that effectively delivers chromium, cobalt, copper, iron, manganese, molybdenum, selenium and zinc to animals. The method of preparing an animal foodstuff composition involves the steps of: providing transgenic algal cells comprising a nucleotide sequence, the nucleotide sequence being capable of expressing a non-native metal-binding protein in the transgenic algal cells; binding the metal-binding protein with at least one metal so as to produce a metal-bound adduct of the metal-binding protein; and admixing the metal-bound adduct with animal foodstuff. The invention is also to a animal foodstuff composition comprising animal foodstuff and transgenic algal cells expressing a non-native metal-binding protein in the transgenic algal cells, such that the transgenic algal cells contain the metal-binding protein and the metal-binding protein being bound to a metal.

  • Publication number: 20140296137
    Abstract: Described herein are compositions and methods for controlling, inhibiting, reducing and/or preventing rotifer growth with antimicrobial peptides. Methods for removing and/or preventing rotifer infestations in algae cultivations by controlling, inhibiting, reducing and/or preventing rotifer growth with an antimicrobial peptide (AMP) are further provided. Also described are transgenic algae comprising an expression vector comprising a nucleic acid sequence encoding an AMP. In some instances, the nucleic acid sequence encoding the AMP is codon-optimized for expression in algae.

    Abstract: The invention provides methods for transgenically controlling physiological post-harvest deterioration (PPD) in plants. Among other aspects, the invention also provides transgenic plants produced by the methods and constructs for creating the plants. According to the present invention, PPD is controlled by expressing one or more transgenes which modulate ROS production or cyanogen levels. Examplary transgenes include alternative oxidase, ROS scavengers, carotenoid biosynthesis genes, and cyanogen metabolism.

  • Publication number: 20130109098
    Abstract: 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.
