Abstract: The present invention is in the field of molecular hydrogen (H2) bio-production, particularly, the present invention provides genetically modified photosynthetic microalgae producing hydrogen in complete growth medium under ambient, continuous growth conditions at cost-effective amounts and to a process for hydrogen production using genetically modified photosynthetic microalga.

Abstract: Methods which utilize a self-assembled structure formed of a plurality of peptides being of from 2 to 6 amino acids in length, and comprising at least one aromatic amino acid residue, wherein the self-assembled structure is capable of interacting with oxygen, are provided herewith. The methods may be for controlling (e.g., reducing) a concentration of free oxygen in an environment, and/or for transporting oxygen from a first environment to a second environment. Further described herein is a self-assembled structure as described herein having oxygen interacted therewith. Further described herein is a composition comprising the self-assembled structure and substance which is oxygen-sensitive and/or participates in an oxygen-sensitive reaction incorporated in the self-assembled structure, systems comprising such a composition and methods employing the composition or system.

Abstract: The present invention relates to the field of drug delivery. More specifically, the invention relates to the preparation and use of a bacteriophage conjugated through a labile/non labile linker or directly to at least 1,000 therapeutic drug molecules such that the drug molecules are conjugated to the outer surface of the bacteriophage. The bacteriophage optionally displays on its coat a ligand that endows it with specificity towards target cells. Thus, there is provided a targeted, high-capacity drug delivery system useful for the treatment of various pathological conditions.
